Abstract A growing number of researchers and practitioners have placed supply chain resilience (SCRE) at the forefront of their research agendas due to an increased susceptibility to disruptive events in the global supply chains. However, empirical research in this area has been hamstringed by the lack of a validated measurement model. In this context, drawing on dynamic capability theory, this research develops a measurement instrument for SCRE. This research conducts a qualitative field study, followed by a quantitative survey. Content analysis is used to explain various dimensions in the qualitative field study, and partial least squares (PLS)-based structural equation modelling (SEM) is used to analyse the data collected in the quantitative survey. The research is conducted with three rounds of data collection and analyses. The results show that SCRE is a multidimensional and hierarchical construct, which consists of three primary dimensions: proactive capability, reactive capability and supply chain design quality. These three primary dimensions are further operationalized through twelve sub-dimensions. The findings also affirm that the SCRE scale potentially better predicts supply chain operational vulnerability (OV) and supply chain performance (SCP) and conforms to the “technical” and “evolutionary” fitness criteria of dynamic capability theory. The implications of these findings are discussed in the context of theory and practice. Limitations and future avenues of research are also discussed.

1. Introduction With the increasing complexity of global business, supply chains are often exposed to numerous disruptions. The detrimental effects of such disruptions are quite pronounced if compounded and not addressed at the right time (Pettit et al. 2013). The consequences are even worse if disruptions are reported in the media, resulting in rapidly declining stock prices (Hendricks & Singhal 2003). For example, after an extended power disruption in Japan due to the 2011 tsunami, Toyota lost over 17% of its value (Kachi & Takahashi 2011). The multiplicity of disruptive events has spurred renewed scholarly interest in supply chain resilience (SCRE) (Pettit et al. 2013; Wu et al. 2006), as attempts to tackle disruptions via traditional risk management approaches are insufficient in the era of highly uncertain and dynamic business environments (Jüttner & Maklan 2011). Therefore, to combat the challenges arising from uncertain and dynamic environments, organizations must develop a resilient approach (Jüttner & Maklan 2011; Brandon-Jones et al. 2014), which Fiksel (2006) defines as the capacity of an enterprise to survive, adapt, and grow in tumultuous times.
Given the enormous importance of SCRE in the event of disruptive events, a comprehensive conceptualization of SCRE is of utmost importance. Organizations and their supply chains must develop both proactive and reactive resilience capabilities to increase the required level of readiness, response and recovery ability during the pre-disaster and post2
disaster phases. Otherwise, supply chain operations will suffer from discontinuity, which adversely affects both the revenues and costs of the whole chain (Ponomarov & Holcomb 2009). Apart from the proactive and reactive aspects, some studies (Craighead et al. 2007; Falasca et al. 2008; Azaron et al. 2008; and others) emphasize the quality of supply chain design in developing SCRE. A review of the extant literature reveals that a theoretically grounded, comprehensive conceptualization and measurement of SCRE is lacking (Ponomarov & Holcomb 2009). A pool of studies (e.g., Pal et al. 2014; Wieland & Wallenburg 2013; Ponis & Koronis 2012; Jüttner & Maklan 2011; Ponomarov & Holcomb 2009; among others) address the significance of SCRE. Wieland and Wallenburg (2013) use proactive and reactive dimensions of resilience, such as robustness and agility. Pettit et al. (2013) and Ambulkar et al. (2015) develop a framework for SCRE assessment. Pettit et al. (2013) deal with seven vulnerability factors and fourteen capability factors to develop a resilience score. Ambulkar et al. (2015) measure SCRE based on four measurement items (coping with changes, being able to adapt to supply chain disruptions, providing quick response, and maintaining high situational awareness) and develop a model of the antecedents of “firm resilience”. The authors conclude that to develop resilience, firms should have a supply chain disruption orientation, a resource configuration and a risk management infrastructure in place. As will be argued later, supply chain design is also an important dimension of SCRE (Ponis & Koronis 2012; Haberman et al. 2015) that we use in our conceptualization of resilience. The theoretical foundations of the framework/model of resilience are also observed to be deficient in extant studies. Although a hierarchical approach to resilience has been studied in the extant literature (Pettit et al. 2013), we take an alternative approach – developing a hierarchical and multidimensional measurement scale for SCRE using the dynamic capability view (DCV) (Teece et al. 1997; Eisenhardt & Martin 2000).
3
The DCV focusses on a firm’s competiveness in a dynamic market of “rapid and unpredictable change” (Eisenhardt & Martin 2000). It is thus an extension of the traditional resource-based view (RBV) of the firm (Wernerfelt 1984; Barney 1991). The essential components of the DCV relate to identifying strategic organizational processes, reconfiguring resources (integrating, gaining, and releasing), and identifying the path to follow to attain competitive advantage (Teece et al. 1997, Eisenhardt & Martin 2000). We argue that supply chain management is a significant strategic organizational process (Tan et al. 2002) for which resilience (or the lack thereof) must be appraised following a structured path; thereafter, corrective actions can be taken by identifying and integrating appropriate resources. Lee (2004) mentions that supply chains need to be “Agile, Adaptable and Aligned” (the triple-A supply chain) to gain competitive advantage. Since the DCV calls for developing appropriate capabilities and reconfiguring resources within firms, we argue that the requirements for a triple-A supply chain can be achieved by managing SCRE via the DCV. We will show that the components of our SCRE scale (proactive, reactive and design elements) are essentially dynamic in nature. These elements also need to be agile and adaptable. We thus take the DCV to conceptualize SCRE. However, the DCV has been criticized for its lack of “empirical grounding” (Eisenhardt & Martin 2000). In this respect, our research contributes significantly by developing and empirically testing a scale for SCRE measurement to determine its effectiveness. In doing so, we adopt the concept of the “technical” and “evolutionary” fitness of the DCV, as proposed by Teece (2007). In line with the research objective, this paper used both qualitative and quantitative methods. In the qualitative approach, we used content analysis on the relevant literature and field study findings to contextualize the measurement instrument. In the quantitative approach, a series of studies were conducted to develop and validate the SCRE scale. Once the dimensions of SCRE were identified from the literature review and the qualitative study, 4
data from study 1 (n = 81 supply chain executives from the apparel industry) were used to select items based on exploratory factor analysis. Subsequently, confirmatory factor analysis (CFA) was conducted on data obtained from study 2 (n = 296 supply chain executives) to examine the factor structure and to provide evidence of dimensionality, scale reliability and validity. Lastly, in study 3, data from 207 supply chain executives from multiple industries were used to test the scale generalizability of SCRE measures. Structural equation modelling (SEM) has been adopted to analyse the collected data. Our findings confirm that SCRE is a hierarchical (third-order) and multidimensional construct, which is measured by the following primary dimensions: proactive supply chain capability, reactive capability and supply chain design quality. These three primary dimensions were further divided into twelve sub-dimensions.
This study makes several important theoretical and practical contributions to the existing literature. First, drawing on the DCV (Teece et al. 1997), this study consolidates the dispersed literature on SCRE and develops and validates an integrated measurement scale for SCRE construct which is a unique contribution. In the spirit of the DCV, this study assumes that supply chains must have proactive features, reactive features and proper design qualities to sense, reconfigure and transform resources in line with environmental changes. Such dynamic capabilities can be viewed as the resilience capabilities of the organizations and their supply chains to overcome these turbulent changes. Second, this research addresses the existing void that studies aligned with the DCV of SCRE have with regard to their empirical and measurement aspects (Eisenhardt & Martin 2000; Ponomarov & Holcomb 2009). Therefore, we contribute to the DCV by using the “technical” and “evolutionary” fitness criteria of Teece (2007) to develop and validate an integrated measurement model for SCRE. The third contribution of this study is the comprehensive development of a hierarchical and multidimensional SCRE scale, which is a major contribution to the literature. The SCRE 5
scale is conceptualized and operationalized as a third-order hierarchical model. Supply chain decision makers will benefit from the findings of our study by developing the necessary proactive and reactive capabilities and ensuring supply chain design quality. The rest of the paper is structured as follows: the next section presents the literature review, followed by a description of the research instrument development process; the subsequent section presents instrument testing, followed by the confirmatory study; the final section presents the discussion and implications, along with limitations and avenues for future research, followed by conclusions.
2. Literature review 2.1 Concept of supply chain resilience Resilience is a multidisciplinary concept. Holling (1973), one of the pioneering researchers of resilience, states that resilience is the ability of a system to absorb changes. Since then, many authors have echoed the concept of resilience as a system’s ability to recover and return to its original state (e.g., Mitroff & Alpasan 2003; Christopher & Peck 2004). In an organizational context, resilience can be characterized as the organizational capability to survive in a turbulent environment (Ates & Bititci 2011). Resilience has ultimately become enormously important in the supply chain domain because of increased disruptions in the global supply chain. However, scholars still debate how SCRE should be conceptualized and measured (Jüttner & Maklan 2011), as the studies are ambivalent in differentiating the measurement and antecedent constructs of SCRE. Existing debates and gaps in the literature necessitate the conceptualization and empirical investigation of SCRE measurement constructs. Bhamra et al. (2011) conduct an extensive literature review on resilience in the context of small and medium-sized enterprises (SMEs). The authors conclude that research to 6
“empirically prove theories” and to determine whether resilience is a “measure, feature, philosophy or capability” is urgently needed. Durach et al. (2015) develop a framework of the antecedents of supply chain robustness, which they conceptualize as a dimension of SCRE. The authors also discuss proactive and reactive strategies to cope with the “turbulence” in supply chains. Hohenstein et al. (2015) conduct a systematic and comprehensive literature review to find the overarching “building elements” of SCRE. The authors conclude that most research in the resilience domain has been qualitative in nature and that research “assessing and measuring” SCRE is genuinely lacking. Scholten and Schilder (2015) follow a case study approach to study the influence of buyer–supplier collaboration in SCRE. The authors show how collaborative activities “enable visibility, velocity and flexibility” and, in turn, SCRE. Wieland and Wallenburg (2012, 2013) conceptualize SCRE as agility and robustness. The authors also argue that an agile strategy is reactive while a robust strategy is proactive. Thus, as is evident from the existing literature, conceptualizations of SCRE can be explained from multiple perspectives. Some studies focus on proactive aspects of resilience (e.g., flexibility, visibility, redundancy, integration, financial strength, and market capability) (Jüttner & Maklan 2011; Pal et al. 2014; Erol et al. 2010), while other studies embrace resilience as both proactive and reactive capabilities (e.g., flexibility, redundancy, agility, recovery time, cost and response effort) (Sheffi & Rice 2005; Christopher & Peck 2004; Falasca et al. 2008; Martin 2004; Vugrin et al. 2011; Pettit et al. 2013). In a similar vein, the proactive and reactive concepts of resilience are also interchangeably defined according to the notions of pre-disaster resilient actions and post-disaster resilient actions (Rose 2004; Wieland & Wallenburg 2013; Sheffi & Rice 2005). In line with the extant literature, we assert that supply chains need both proactive and reactive capabilities to adapt, integrate and reconfigure during the pre-disaster and post-disaster phases surrounding disruptive events.

An examination of the extant literature also reveals that studies, such as Craighead et al. (2007), Falasca et al. (2008), Azaron et al. (2008), introduce the concept of supply chain design factors that reduce supply chain vulnerability and increase resilience. According to the authors, a “complex and critical supply chain” is more susceptible to disruptions that affect the resilience of the supply chain. The success of supply chain managers depends on their ability to select appropriate strategies with regard to supply chain design. For example, in an environment of supply uncertainty, adopting multiple suppliers helps reduce supply side vulnerabilities. Selecting such strategies can be attributed to defining the path of competencies in uncertain environments. We argue that, depending on the context, supply chain design can be considered either proactive or reactive. For example, to satisfy customers’ needs, companies deliberately design appropriate supply chain (proactive design) (Vonderembse et al. 2006). However, supply chain design is also dynamic in responding to changes in the environment (reactive design) (Harland et al. 2003). Companies need to redesign the supply chain based on their experiences of disruptions in the supply chain (Fiksel 2006; Chowdhury & Quaddus 2015). Therefore, we have treated supply chain design as another dimension of SCRE.
2.2 Proactive aspects of supply chain resilience Supply chains need proactive capabilities to be resilient against disruptions (Pettit et al. 2010; Christopher & Peck 2004; Jüttner & Maklan 2011). Hollnagel et al. (2006) mention the proactive resilience capability of a system as the capability to recognize, anticipate and defend against the changing shape of risk before adverse consequences occur. Tenhiala and Salvador (2014) emphasize the need for a formal communication channel to cope with disruptions and improve resilience. Supply chain research emphasizes different proactive capabilities such as flexibility, redundancy/reserve capacity, robustness, adaptability, 8
collaboration, integration, visibility, market strength, financial strength, diversity, and efficiency to measure resilience (Pettit et al. 2010; Pettit et al. 2013; Pal et al. 2014; Sheffi & Rice 2005; Fiksel 2003; Ponomarov & Hollcomb 2009). In addition, Jüttner and Maklan (2011) focus on proactive capabilities such as flexibility, velocity, visibility and collaboration. Further, the risk management literature provides a handful of studies (e.g., Knemeyer et al. 2009; Grötsch et al. 2013; Sullivan & Branicki 2011; and others) that discuss proactive capabilities such as proactive planning, buyer–supplier relational quality, resourcefulness, readiness and rapidity to mitigate disruptions in organizations and their supply chains. Based on the commonalities in the literature, flexibility, redundancy/reserve capacity, integration, efficiency, market strength, and financial strength can be regarded as proactive supply chain capabilities. Although a number of studies identify different proactive capabilities to mitigate supply chain disruptions (e.g., Jüttner & Maklan 2011; Pettit et al. 2013), empirical validation of the dimensions of supply chain proactive capabilities and their sub-dimensions has yet to be established. Therefore, this study validates supply chain proactive capabilities and their sub-dimensions within a hierarchical and higher-order SCRE scale. 2.3 Reactive aspects of supply chain resilience In line with Sheffi and Rice (2005) and Ponomarov and Holcomb (2009), the reactive facets of SCRE can be established based on the response and recovery abilities of organizations. Supply chain response concerns mitigating disruptions in the shortest possible time and with the smallest impact (Pettit et al. 2013). The ability to respond quickly to market needs during critical situations is an important determinant of SCRE (Sheffi & Rice 2005; Wieland & Wallenburg 2013). Hence, we also argue that supply chains should be able to
9
respond quickly to return to normal or stronger positions. To explain the resilience capability of successful companies during the global financial crisis, Jüttner and Maklan (2011) state that resilient companies can respond to environmental changes more quickly than their nonresilient counterparts. An organization’s ability to respond quickly to environmental forces is arguably a distinctive capability that is a unique source of competitive advantage. Recovery from disruptions is a critical and distinctive capability of organizations and their supply chains. Some systems, whether a business network, an ecological system or a nation, can recover quickly from disasters because of their idiosyncratic capabilities. In line with the research of Wang et al. (2010), Sheffi & Rice (2005) and Välikangas (2010), such capabilities can be attributed as the resilience of a dynamic system. The extant literature (Wang et al. 2010; Sheffi & Rice 2005; Willroth et al. 2001; and others) mostly measures resilience in terms of recovery time. However, the cost of recovery effort should also be considered (Vugrin et al. 2011). Martin (2004) includes cost as a parameter for measuring resilience. Similarly, other studies, such as Vugrin et al. (2011), emphasize on the cost of resilience. A system may recover in less time (Wang et al. 2010), with less effort and at lower cost (Vugrin et al. 2011) because of its efficiency and unique ability to absorb the shock (Holling 1973) or reduce the impact of the disruption (Rose 2004) or its inherent ability to return to its original position (Christopher & Peck. 2004). Therefore, resilience can be measured by the extent of recovery time, cost, disruption absorption and ability to reduce the impact of the loss. Although a few studies illustrate the concept of supply chain reactive capability to explain SCRE, the literature lacks empirical validation of supply chain reactive capabilities. Therefore, this study empirically validates the supply chain reactive capabilities within the SCRE scale.

2.4 Supply chain design quality A number of studies (Craighead et al. 2007; Falasca et al. 2008; Speier et al. 2011; Ponis & Koronis 2012; among others) illustrate the relevance of supply chain design issues for supply chain risk and SCRE. For example, Ponis and Koronis (2012) characterize SCRE as the ability of a supply chain to proactively plan and design its network to anticipate ensuing supply chain disruptions and to respond to disruptions effectively. Haberman et al. (2015) study the impact of the dispersion and co-location of supply chain partners to reduce supply chain disruption risk. In line with previous studies (e.g., Craighead et al. 2007; Falasca et al. 2008), supply chain design quality is conceptualized in terms of supply chain node density, complexity and criticality. Node density is high in a supply chain where a large number of nodes exist in a limited geographical area (Craighead et al. 2007; Falasca et al. 2008). Supply chain nodes exist in high-density clusters when the sources of supply or distribution markets are concentrated in a particular area. By contrast, nodes are expanded when the sources of supply and the markets are diverse (Kleindorfer & Saad 2005). Craighead et al. (2007) and Falasca et al. (2008) emphasize that increased density in the supply chain creates more vulnerabilities and reduces SCRE. Therefore, node density is an important attribute of supply chain design quality. Complexity is related to both the number of nodes in a supply chain and the interconnections between those nodes (Craighead et al. 2007). For example, the large number of forward and backward flows in the supply chain (Bozarth et. al. 2009) due to the numerous components and parts required for the product and the extensive inter-firm relations among different members in the supply chain network (Choi & Krause, 2006) makes a supply chain more complex (Craighead et al. 2007; Perona & Miragliotta 2004). A less complex supply chain would have fewer nodes and/or fewer interconnections between nodes (Craighead et al. 11
2007; Falasca et al. 2008). Increased complexity in the supply chain usually creates more vulnerabilities (Craighead et al. 2007; Falasca et al. 2008). However, additional nodes that create a buffer in the supply chain reduce vulnerability. For example, sourcing from multiple suppliers instead of a single supplier increases supply chain node complexity but reduces vulnerability through enhanced flexibility and resilience (Falasca et al. 2008; Wagner & Bode 2006). Sourcing from alternative suppliers, which opens alternatives during supply disruptions, is another way to reduce vulnerability (Jüttner 2005; Berger et al. 2004). Arrangements with alternative suppliers also allow the organization to reduce supply cost risks, i.e., supply disruptions due to cost inflammation (Tang & Tomlin 2008). Node criticality depends on the relative importance of a given node or set of nodes within a supply chain (Craighead et al. 2007). A very important node (e.g., an important distributor or supplier on which others in the supply chain are highly dependent) makes the supply chain critical and vulnerable. A critical transportation hub during sourcing and distribution (e.g., freight consolidation in Singapore) also creates supply chain criticality (Craighead et al. 2007). Alternate distribution channels are important when a critical transportation hub exists during sourcing and distribution (Craighead et al. 2007; Falasca et al. 2008). Colicchia et al. (2010) have also shown the effectiveness of using alternative transportation modes to reduce transportation risk while outsourcing from a complex and distant location. Thus, supply chain node criticality is an important element of supply chain vulnerability and SCRE. 2.5 Theoretical justification The need for resilience capability requirements in the wake of disruptive events can be analysed through the lens of the DCV (Teece et al. 1997), which is an extension of the RBV (Wernerfelt 1984; Barney 1991). The RBV stresses that organizations need to develop
12
capabilities to overcome difficulties and to gain competitive advantage. However, the traditional RBV lacks proper delineation of capabilities when dynamic changes occur in uncertain environments. The DCV addresses this gap in the traditional RBV by planning appropriate resources and capabilities to respond to situation-specific changes (Teece et al. 1997; Eisenhardt & Martin 2000), thereby addressing the idiosyncrasies of contingencies. The basic premise of the DCV is a firm’s capacity to integrate, build and reconfigure organizational resources using its processes to respond to environmental changes and uncertainties and to design new value-creating strategies (Teece et al. 1997; Eisenhardt & Martin 2000). In the same vein, we argue that organizations’ supply chains need to develop dynamic capabilities to mitigate vulnerabilities in an uncertain environment, which necessitates resilience capabilities to survive in the long run. The proactive and reactive capabilities of SCRE can be expounded upon through the lens of the DCV (Teece et al. 1997). According to the DCV, firms must have the capability to adapt, integrate, and reconfigure their resources and capabilities to address rapidly changing environments. To accelerate such changes, organizations must be proactive in scanning environmental changes and obtaining the necessary flexibility and adaptability (Teece et al. 1997) which, in our study, is commensurate with the supply chain proactive capability to adapt to environmental changes and to prevent potential vulnerabilities in the supply chain. The DCV (Teece et al. 1997) stresses that winning companies in the market should reconfigure their resources and capabilities quickly to recover competencies during turbulent times. We also argue that supply chains should have the reactive capability to reconfigure resources and capabilities to recover quickly from disruptions. Pettit et al. (2013, pp. 47) introduce the concept of “balanced resilience”, which is essentially the balance between increasing resilience capabilities and increasing costs to control vulnerabilities. Grounded in the DCV, Ponomarov and Holcomb (2009) emphasize 13
the importance of resource/capability specificity and their adequate measurement to sustain profitability by improving the resilience balance. Although the extant literature (e.g., Jüttner & Maklan 2011; Christopher & Peck 2004; Ponomarov & Holcomb 2009, etc.) provides a framework for resource specificity of SCRE, the tenets of resource measurement for SCRE are still lacking (Ponomarov & Holcomb 2009). The central premise of this study is to explain and extend the measurement aspect of dynamic capabilities in the context of SCRE to combat challenges arising from environmental uncertainties. In this study, we propose the specification and measurement of dynamic capabilities in terms of proactive and reactive capabilities in the context of SCRE. Therefore, this study provides a significant extension of dynamic capability theory. Based on the discussions above on the DCV and its links with the dimensions of SCRE, this paper conceptualizes SCRE as “the characteristics of a well-designed supply chain network with proactive and reactive capabilities, which enables the supply chain members to reduce the probability of disruptive events (or to reduce their impact) to take the organization to a stronger and more sustainable state”. Our extended definition of SCRE is in line with the notion of resilience put forward by Fiksel (2006), who conceptualizes enterprise resilience as “the capacity for an enterprise to survive, adapt, and grow in the face of turbulent change”. In line with the DCV, companies can use disruptions as opportunities to learn, grow, and perhaps move to a different “state” by allocating idiosyncratic resources through SCRE management. 3. Methodology To develop a scale to measure SCRE, we have followed the research process shown in Table 1, in line with Akter et al. (2013), Rosenzweig and Roth (2007) and Shafiq et al. (2014). This study appropriately uses both qualitative and quantitative approaches to conduct the research. In doing so, the recommendations of Fawcett et al. (2014) are strictly followed. 14
In the context of qualitative research, Fawcett et al. (2014) recommend that the context of the study, the sample, and data analysis be transparent. In our research process, we conduct a qualitative study in two phases: an extensive literature review to conceptualize SCRE and a field study to explore the dimensions of SCRE further. In each phase, we follow the recommendations of Fawcett et al. (2014) (see the next section for further detail). In addition, Fawcett et al. (2014) mention that good quantitative research must elucidate the following: the sample frame and characteristics, data collection/questionnaire administration, nonresponse bias, common method bias, scale development, measurement validation, and (data analysis) method selection. In our research, an extensive quantitative study is conducted during the instrument testing and scale generalizability phase. We strictly follow all the recommendations suggested by Fawcett et al. (2014) (see the following sections for further detail). Our study also follows the guidelines and recommendations of MacKenzie et al. (2011) for scale development. The scale development procedure specified by MacKenzie et al. (2011; Figure 1, pp. 297) includes Conceptualization, Development of measures, Model specification, Scale evaluation and refinement, Validation and Norm development. Our scale development process (Table 1) is very much in line with the procedure of MacKenzie et al. As will be shown later, we conceptualize SCRE as having both reflective and formative indicators. Hence, we pay special attention to the discussions by MacKenzie et al. (2011, pp. 300-303) with regard to reflective and formative indicators in scale development. (Insert Table 1 about here) 3.1. Conceptualization of supply chain resilience (SCRE) To conceptualize the dimensions of SCRE, this study began by investigating commonly cited items for each dimension of SCRE, as outlined in the literature review section. The literature
15
review reveals that SCRE is a multidimensional and hierarchical concept. Through this process, three primary dimensions were identified that reflect SCRE: proactive supply chain capability, reactive supply chain capability and supply chain design quality. However, the literature review also reveals many sub-dimensions for each of these primary dimensions. The SCRE capability is also found to be context dependent (Pettit et al. 2013). Therefore, we conducted an exploratory qualitative study to explore the sub-dimensions of the three primary dimensions of SCRE and to confirm the contextual appropriateness of the dimensions identified in the literature review. 3.2. Instrument development process The formal instrument development process started with a qualitative field study. The findings from the qualitative study were then justified based on the literature. Item creation and item sorting were then performed for scale development.
3.2.1 Qualitative study This study collected data from the apparel industry in Bangladesh, one of the leading apparel exporters in the world. The apparel industry is the economic propeller of Bangladesh, accounting for 78.6% of total export earnings and direct employment for over 4 million workers, of which 80% are women. In 2011, apparel exports from Bangladesh amounted to USD 19.90 billion, making the country the second largest apparel exporter in the world (BGMEA 2012). Despite its huge potential, the apparel supply chain is facing a climax situation due to the multiple challenges, such as labour unrest due to human rights violations, poor wages, a lack of safety measures and hazardous working environments, environmental pollution, political instability, interruptions in utility supply, power shortages, and inefficient customs and port management (Islam et al. 2012; Islam & Deegan 2008; Haider 2007; Paul-
16
Majumder 2001; Nuruzzaman 2009). These challenges pose threats to the sustainability of apparel supply chain in Bangladesh and thus call for an exploration of the resilience capabilities of the apparel supply chain in Bangladesh. In our study, we obtained qualitative data from 15 in-depth interviews conducted with supply chain decision makers in apparel manufacturing companies, accessory producing companies (suppliers) and buying agents. Table 2 presents the profile of the respondents. Each interview lasted for approximately 45–60 minutes. In each case, respondents were asked a number of questions to explore their SCRE practices to mitigate supply chain vulnerabilities. The interview responses were recorded, scripted, coded and categorized to identify the themes and sub-themes for different dimensions of SCRE. The extracted dimensions were then matched with the literature to support our findings to ensure the content validity of the measurement instrument. For the sake of brevity, the details of the qualitative study are not reported in this paper. Table 3 summarizes the factors and variables derived from the qualitative study and the enterprises (interviewees) that expounded upon the specific variables. (Tables 2 and 3 about here) 3.2.2 Justification of field study findings based on the literature The constructs and variables from the field study were confirmed based on evidence provided in the literature. The selected factors and variables in the field study were derived based on the commonalities in and consistency of the responses. Table 4 presents the factors and variables that align with the relevant literature. As shown in Tables 3 and 4, SCRE is a multidimensional construct that can be measured by the following dimensions: proactive capability, reactive capability and supply chain design quality. Supply chain proactive capability is measured by the following dimensions: supply chain disaster readiness,
17
flexibility, reserve capacity, integration, efficiency, market strength and financial strength. The reactive capability is measured by the response and recovery dimensions. Finally, supply chain design quality is measured by the following dimensions: the density, complexity and criticality of the network. These constructs and their interrelationships are the inputs for our research model. Table 4 also shows the items that fall under the constructs “operational vulnerability” (OV) and “supply chain performance” (SCP) constructs. These two constructs are used to test the nomological validity of the SCRE scale, which is described in section 3.3.3 below. (Table 4 about here) 3.2.3 Scale development To develop scales for the SCRE dimensions (i.e., proactive capability, reactive capability, and supply chain design quality), item creation and item sorting were performed next (Akter et al. 2013; Rosenzweig & Roth 2007; Shafiq et al. 2014). On the one hand, item creation was performed to ensure content validity by selecting the appropriate items for the construct. On the other hand, item sorting was conducted to affirm both content validity and construct validity by determining the convergence and divergence of the items for each dimension. After the item sorting and pretesting procedure, the refined instrument was tested in a pilot study. In the pilot study process, factors were categorized through exploratory factor analysis, and the findings resembled those in the literature and the field study.
3.2.3.1 Item creation Using the existing literature, a pool of items for each SCRE dimension was created. To develop a parsimonious SCRE scale, we very carefully selected the items for each dimension from the existing literature. For example, in previous studies (Swafford et al. 2006; Braunschidel & Suresh 2009), supply chain flexibility has been measured by a large 18
number of items; however, we selected the items most relevant to SCRE and the research context. The findings from the qualitative study were compared with the existing literature to determine which items to add or delete from the item pool created from the literature review. To develop scales for supply chain proactive capability, most of the items were adapted from Pettit et al. (2013); however, no valid and reliable scales were identified to measure reactive capability and supply chain design quality. Therefore, new scales must be developed for these constructs. For reactive capability, such as the response and recovery sub-dimensions, items were selected from a number of studies (e.g., Sheffi & Rice 2005; Pettit et al. 2013; Vugrin et al. 2011) with context-specific modifications. To develop items for supply chain design quality, items were selected mainly from the study of Craighead et al. (2007). Finally, item pools were created for the twelve sub-dimensions of SCRE with an extensive re-evaluation of the existing items from the literature and the qualitative study and the addition/adaptation of new items to contextualize the study model. The seeming redundant or confusing items were eliminated. The selected items went through further reliability and validity tests in the quantitative phase of the study.
3.2.3.2 Item sorting As mentioned earlier, item sorting was conducted to ensure domain coverage and the reliability of the items under each construct. First, we evaluated the domain coverage using the judgements of three experts (two scholars and one supply chain manager). The experts applied the Q-sort procedure, which ensures the correct placement of items under different constructs, to sort each SCRE sub-dimension item (Rosenzweig & Roth 2007). This procedure provided adequate evidence of construct validity with respect to the selected items under each construct. Second, two different experts (a scholar and a supply chain manager of the Bangladesh Garment Manufacturers and Exporters Association (BGMEA)) undertook two rounds of sorting. Using the data from the two rounds of the Q-sort process, the 19
reliability of the item classifications for different dimensions was assessed. Reliability was evaluated based on the placement ratio of the items under a specified dimension/construct. The item placement ratio results from the final round (see Table 5) show that a total of 125 correct placements (or “hits”) were achieved out of 147 possible item placements (49 measurement items with 3 respondents), resulting in an aggregated hit ratio of 84.6% (see Table 5). In this Q-sorting process (the final round), no individual hit ratio fell below 75%, which is the accepted cut-off value according to Menor and Roth (2007). Table 5 also shows that the associated average kappa (Cohen 1988) (the average from rounds 1 and 2) for the inter-judge agreement scores for each construct exceeds the cut-off value (≥65%) for interjudge agreement scores (Moore & Benbasat 1991; Akter et al. 2013). Therefore, based on the overall findings, an aggregate of 49 items from different sub-dimensions was selected for the preliminary questionnaire development (Table 7). (Table 5 about here) 3.3 Instrument testing The instrument testing process started by developing a primary version of the questionnaire and pretesting the questionnaire to make necessary modifications. Following the pretesting process, a pilot study was conducted to identify the factor structure through exploratory factor analysis. Based on the dimensions identified from exploratory factor analysis, a SCRE model was then specified and tested through a confirmatory study.
3.3.1 Development of initial questionnaire and pretesting A primary version of the questionnaire was prepared, and the 62 questions (49 corresponding to SCRE scale) were answered on a 6-point Likert scale. For the sake of brevity, the questionnaire is not included in the paper. Before conducting the pilot study, the developed instrument was pretested on 10 respondents (4 supply chain managers from 20
apparel manufacturing companies, 3 from accessory producing companies, 1 buyer/buying agent and 2 supply chain scholars) to ensure that the questions were appropriate in terms of their wording, order, layout and clarity. Based on respondents’ feedback, some statements in questionnaire needed further clarification. For example, the “contract flexibility with supply chain partners” item was elaborated by adding partial orders, partial shipments and partial payment facility (see FLX4 of Table 7). All comments were considered in the final design of the questionnaire. The final version of the questionnaire was then prepared for a pilot study to test the instrument.
3.3.2 Pilot study The pilot study of the SCRE scale was conducted with real data. Supply chain managers were targeted for data collection. One hundred ten managers were approached, and 86 managers (54 managers from apparel manufacturers, 25 from accessory supplying companies and 7 from buying agents) ultimately agreed to participate in the survey. After two rounds of follow up, 86 responses – 5 of which were found to have incomplete data or to be extreme outliers – were obtained. These five responses were discarded, resulting in 81 usable responses from the pilot study. We used a back-translation procedure (Brislin 1970) to translate the questionnaire into the local Bengali language. As literal back-translation suffers from conceptual equivalence issues, we used a collaborative team approach (inviting two other academics) to achieve the conceptual equivalent back-translation (Douglas & Craig 2007). The respondents were offered both English and Bengali versions of the questionnaire. Most of our respondents chose the English version of the questionnaire. However, they also took the Bengali version as a backup to clarify some questions. This practice was followed for all subsequent data collection and worked very well.
21
Table 6 presents the demographic profile of pilot study respondents. We conducted exploratory factor analysis on the pilot study (see Table 7) data using the varimax rotation procedure to assess the initial measurement scale. We also used the Kaiser–Meyer–Olkin (KMO) test and Bartlett’s test of sphericity to evaluate the appropriateness of the factor analysis. The KMO test ensured the overall sampling adequacy with a value of 0.725 (>0.50). Bartlett’s test of sphericity provided evidence of the validity of the instrument (2167.958, df = 1035, significant at p = 0.000). Twelve factors with eigenvalues of greater than 1 were extracted (see Table 8). The twelve components had a cumulative variation explained of 71.050%. In evaluating the results of the factor analysis, items were deleted that had loadings of <0.40 or that had cross loadings (>.5) with other factors. The Cronbach’s alpha values corresponding to each construct were also examined to ensure reliability, revealing that the Cronbach’s alpha values of the extracted factors exceeded the minimum threshold of 0.70. For further scale refinement, corrected item–total correlation was also examined to improve reliability (see Table 8). The initial instrument was refined by removing items with low loadings or cross-loaded items. Thus, of the initial 49 items, 40 items were retained for the next stage of confirmatory analysis. (Tables 6, 7 and 8 about here) 3.3.3 Model specification Based on the factor structure of SCRE in the exploratory study and evidence from the literature, a research model (see Figure 1) is proposed to measure the dimensions of SCRE and their relationship with supply chain OV and SCP. We postulate SCRE as a hierarchical (third-order) model with three primary dimensions (i.e., supply chain proactive quality, supply chain reactive quality, and supply chain design quality) and twelve sub-dimensions.
22
Regarding the issue of reflective and formative constructs, we first followed the decision criteria of Jarvis et al. (2003) and Polites et al. (2011). We thus argue that the relationship of the focal construct with sub-constructs (second- and third-order constructs; see Figure 1) can be operationalized as reflective (Jarvis et al. 2003). For example, in this study, proactive resilience capability is reflected by the supply chain readiness, flexibility, reserve capacity and integration sub-dimensions. These sub-dimensions are interrelated and interdependent; for example, to increase flexibility, reserve capacity and integration is essential (Sheffi & Rice 2005). Moreover, integration and redundant capacity are also interrelated (Chen & Daugherty 2009). For first-order constructs, we followed the guidelines of MacKenzie et al. (2011), who argue that “Constructs are not inherently, formative and reflective in nature, and most can be modelled as having either formative or reflective indicators…” (p. 302). MacKenzie et al. (2011) also state that, from an ontological perspective, a construct with reflective indicators is a “real entity that exists independently”, while a construct with formative indicators is “seen as a theoretical construction (rather than real entity)”, which is constructed by the items of the construct (pp. 303). Therefore, in our study, we heeded the recommendations of three academic experts to decide on the reflective and formative constructs at the first-order level 1 . The three academic experts are knowledgeable in the SCRE area. After two rounds of semi-Delphi opinion collection, we settled on flexibility, integration, financial strength, response and recovery as reflective constructs and reserve capacity, efficiency, market strength, density, complexity, criticality, and disaster readiness as formative constructs (see Figure 1). Hence, SCRE is a mixed reflective–formative type of multidimensional, hierarchical construct. (Insert Figure 1 about here)

We are indebted to one of the reviewers who suggested this.
23
To assess the nomological validity of the higher-order reflective SCRE model, we tested the relationship with related outcome constructs (Churchill 1995). Well-grounded theoretical support allows us to a negative relationship between SCRE and supply chain OV (Jüttner & Maklan 2011; Ponomarov & Holcomb 2009) and a positive relationship between SCRE and SCP (Pettit et al. 2013; McCann et al. 2009). In line with Sheffi (2005; p. 25), we assert that OV comprises “everything from supplier disruptions to theft by employees. These are mainly disruptions to the means of production”. Sheffi (2005; p. 25) categorizes vulnerabilities as financial, hazard, strategic and operational risks. We claim that financial, hazard and strategic vulnerabilities can be grouped as “non-operational” vulnerabilities. Figure 1 shows the resilience model with its predicted relationship between OV and SCP.
The literature shows that SCRE is essential in reducing vulnerabilities (Christopher & Peck 2004; Ponomarov & Holcomd 2009; Pettit et al. 2013). The extant literature also reveals a multiplicity of OV factors, such as utility crisis, poor quality, supply problems due to the loss of key suppliers or problems in the suppliers’ plants, logistics mode and route disruptions, and IT system failures (Blos et al. 2009). These vulnerability factors have a huge impact on the supply chain if they are not addressed in time (Ponomarov & Holcomb 2009), particularly when disruptions have spiral effects on the supply chain network (Christopher & Lee 2004). For example, disruptions in the suppliers’ plants have an impact on the operations of manufacturers and the sales of distributors. As noted earlier, Ericsson lost USD 400 million in revenue due to a fire in its chip supplier’s plant (Tomlin 2006). However, due to its resilient approach, Nokia overcame the OV arising from a similar disruption, which saved it from potential financial losses and delays in serving customers (Tomlin 2006). Pettit et al. (2013) show that SCRE has a positive impact on SCP. Hendricks and Singhal (2003) reveal that announcing supply chain disruptions (such as an operational issue or a delay in shipment) decreases shareholder value significantly. Therefore, the development of resilience 24
capabilities is essential to mitigate OV, thereby reducing economic losses and securing SCP. These arguments indicate the dynamic relationships between SCRE and OV and between SCRE and SCP. Therefore, the arguments above lead us to posit the following hypotheses: Hypothesis 1 (H1): Supply chain resilience has a direct negative impact on operational vulnerability. Hypothesis 2 (H2): Operational vulnerability has a direct negative impact on supply chain performance. Hypothesis 3 (H3): Supply chain resilience has a direct positive impact on supply chain performance. Hypothesis 4 (H4): Supply chain resilience has an indirect impact on supply chain performance through mitigating operational vulnerability.
3.3.4 Confirmatory study Although the items and the factor structure of the proposed SCRE scale were validated in the pilot study, it provided little evidence of convergent and discriminant validity. As a result, we used confirmatory factor analysis (CFA) (McFarlan et al. 1983) to thoroughly assess the refined instrument using larger samples. Data were collected from a cross-section of garment manufacturers, accessory producers and buying agents via face-toface and mailed surveys. Three hundred fifty respondents were targeted for this phase of the study. Ultimately, 296 usable responses were collected. Table 9 shows the profile of the respondents. The sample size of 296 is adequate for data analyses using partial least squares (PLS)-based SEM (Chin 1998; Chin & Newsted 1999), which is our chosen method. We performed a non-response bias (more specifically, late response bias) test on the early and late respondents (Armstrong & Overton 1977) based on the selection of some variables. Table 10 shows that response bias is not a cause for concern in our data. As the data were collected from a single respondent from each firm and were gathered using a crosssectional research design, common method variance may result in systematic measurement 25
error (Huber & Power, 1985). Following Podsakoff et al. (2003), several efforts were made to reduce the chance of common method bias ex ante. First, data were carefully collected from respondents who possessed relevant knowledge in the subject area. For example, the supply chain managers or the people involved in supply chain functions within an organization were selected. Second, the respondents were assured that their responses would remain anonymous. Third, the questions were designed to be simple and specific to avoid ambiguity. Some terminology was explained with relevant examples so that the respondents could easily understand the intended meaning of the scale item. Fourth, the researcher attempted to avoid double-barrelled questions. Fifth, the independent and dependent variables in the survey was addressed separately. As shown in Figure 1, SCRE is the only exogenous variable in our research model (Figure 1), which has two endogenous variables: OV and SCP. Three primary sources of endogeneity problems are “omitted variables”, “simultaneity” (also referred as the “direction of causality”), and “measurement error”. For detailed discussions of these issues and more, see Roberts and Whited (2013) and Guide and Ketokivi (2015). We are confident of the direction of causality in our research model, as detailed in the hypothesis development section above. Hence, the direction of causality (Guide & Ketokivi 2105) does not present any endogeneity problem in our case. We have attempted to minimize the measurement errors following an extensive procedure of measurement item selection and data collection and conducting extensive reliability and validity tests of our instruments. However, as with any other research model, the issue of omitted variables will remain a limitation of our model. (Tables 9 and 10 here) To estimate the hierarchical SCRE model, this study applied PLS-based SEM (Chin 1998) for the following reasons. The research model developed in this study is hierarchical 26
and complex, containing 18 constructs (i.e., 12 first-order, 3 second-order, 1 third-order and 2 outcome constructs) and 40 items. Because of its component-based approach, PLS-based SEM will be able to easily find solutions to this complex hierarchical model (Chin 1998, Hair et al. 2013). PLS also helps achieve more theoretical parsimony and less model complexity in assessing the hierarchical model (Akter et al. 2013). In addition, the research model includes both formative and reflective measurement constructs. PLS-based SEM can readily handle formative and reflective constructs in the same model (Hair et al. 2011). Based on the arguments above, this study deployed PLS-based SEM (Smart PLS v. 3) to estimate this hierarchical, multidimensional SCRE model. PLS has recently been used for scale development, and it also has a goodness-of-fit (GoF) measure (Akter et al. 2013). Therefore, using PLS-based SEM seemed logical to develop and validate a multidimensional and hierarchical SCRE model. To estimate the higher-order construct of SCRE, this study used a two-stage approach to simplify the model (Wetzels et al. 2009; Becker et al. 2012). Nonparametric bootstrapping (Efron & Tibshirani 1993; Wetzels et al. 2009) has also been applied with 1,000 replications to obtain the standard errors of the estimates.
3.3.4.1 Assessment of the first-order items The data were initially screened, and missing data for any item were replaced by the mean values of that item, in line with Hair et al. (2013). Table 11 presents the results of the first-order item assessment, along with the means and standard deviations of all items. The means are generally greater than 4 on a six-point scale. Hence, our sample items do not follow a normal distribution, which poses no problem because we are using PLS for data analysis. For covariance-based SEM (e.g., LISREL or AMOS), an estimator that can address non-normal distribution, for example, robust weighted least squares (WLS), must be used. For more information, see Finney and DiStefano (2013). With regard to construct reliability, the results clearly show that the composite reliability (CR) for all of the subscales ranges 27
from 0.845 to 0.917, which meets the threshold value of 0.7 suggested by Nunnally (1978) and Hair et al. (2011). Convergent and discriminant validity were tested to assess the construct validity of the SCRE scale. The average variance extracted (AVE) for each factor/construct (see Table 11) and the loading of the items corresponding with each factor/construct were inspected to examine the convergent validity of the SCRE scale. The analysis shows that the AVEs ranged from 0.681 to 0.813, exceeding the minimum threshold of 0.5 (Fornell & Larcker 1981; Henseler et al. 2009; Hair et al. 2011). Table 11 also shows that some items have been deleted due to low loadings and/or high cross-loadings. All other remaining items have significant loadings and/or weights at p < 0.01 (see Table 11) (Henseler et al. 2009; Hair et al. 2011). Thus, the scale for the SCRE dimensions possesses adequate convergent validity. The SCP outcome construct has been modelled as a reflective construct in line with the literature (Pettit et al. 2013; McCann et al. 2009); this construct also possesses adequate item reliability (all loadings > 0.7), with an AVE of 0.775 and CR of 0.853. However, the OV outcome construct has been modelled as a formative construct (Jüttner & Maklan 2011; Ponomarov & Holcomb 2009). Table 11 shows that the item weights and/or loadings are all significant for this construct (Hair et al. 2011).
In a recent paper, Henseler et al. (2015) show that the heterotrait-monotrait (HTMT) ratio of correlations is superior to Fornell and Larcker’s (1981) AVE-SE method for testing discriminant validity. Therefore, we used the HTMT method to test the discriminant validity of the SCRE scale. Table 12 presents the HTMT results for all the SCRE constructs. The low values (<0.85; Henseler et al. 2015) in Table 12 confirm the discriminant validity of the scale. High multicollinearity among the indicators in formative constructs can pose problems. Hair et al. (2011) recommend 5 as the maximum threshold value for the variance inflation factor (VIF) in detecting multicollinearity. Table 13 shows that multicollinearity is not a problem for the formative constructs in our study. Therefore, we conclude that the 28
measurement model is satisfactory given the evidence of adequate reliability, convergent validity, discriminant validity and a lack of multicollinearity among the formative constructs. (Tables 11, 12 and 13 about here) 3.3.4.2 Assessment of the higher-order scale The results of higher-order assessment are shown in Table 14. Table 14 clearly shows that the CRs and AVEs of the higher-order scales are greater than 0.70 and 0.50, respectively, providing evidence of reliable higher-order measures. An assessment of the higher-order constructs also confirms that the SCRE has a strong association with the second-order constructs of supply chain proactive capability (β = 0.886, t = 85.2), supply chain design (β = 0.762, t = 75.4), and supply chain reactive capability (β = 0.839, t = 52.8) (see Figure 2), which explains 87.9%, 66.5%, and 78.6% of overall SCRE variance, respectively (see Figure 2). This assessment also affirms that supply chain proactive capability has a strong association with flexibility (β = 0.796, t = 43.72), reserve capacity (β = 0.679, t = 12.48), integration (β = 0.868, t = 76.8), efficiency (β = 0.748, t = 38.25), market strength (β = 0.839, t = 79.21), financial strength (β = 0.812, t = 87.15) and supply chain readiness (β = 0.823, t = 80.79). The supply chain design has strong associations with node density (β = 0.868, t = 84.2), complexity (β = 0.856, t = 88.3), and node criticality (β = 0.752, t = 312.6). Finally, the supply chain reactive capability has a strong association with supply chain response (β = 0.834, t = 91.7) and supply chain recovery (β = 0.865, t = 94.8) (see Figure 2). (Table 14 and Figure 2 about here) 3.3.4.3 Assessment of the nomological and predictive validity As noted above, this study obtained the following R2 (the coefficient of determination) values, which are rather large (>0.50) (Hair et al. 2011): 0.879 for proactive capability, 0.665 for supply chain design quality and 0.786 for reactive capability (see Figure 29
2). In addition, the nomological and predictive validity of the higher-order multidimensional SCRE construct is assessed by examining its relationship with the following outcome constructs (Akter et al. 2013; Mackenzie et al. 2011): “supply chain operational vulnerability” and “supply chain performance”. The results yield standardized beta coefficients of β = -0.615 (t = 14.36) from SCRE to supply chain OV, β = -0.092 (t = 2.59) from supply chain OV to SCP, β = 0.703 (t = 19.82) from SCRE to SCP and β = 0.419 (t = 8.78) from SCRE to SCP through OV (see Figure 2 and Table 15). The path coefficients are all significant (p < 0.001) (see Figure 2 and Table 15), thus supporting hypotheses 1, 2, 3 and 4. As all these path coefficients are significant (p < 0.001), the nomological validity of SCRE is ensured (Akter et al. 2013). This study also used Stone–Geisser’s Q2 (Stone 1974; Geisser 1974) to test the predictive validity of the higher-order multidimensional SCRE construct. Using a cross-validated redundancy approach, this study obtained Q2 values of 0.63 for supply chain OV and 0.579 for SCP. To ensure high predictive validity, Q2 should exceed zero (Chin 2010; Fornell & Bookstein 1982). Therefore, the results of this study reveal the predictive validity of the higher-order SCRE measurement. (Table 15 about here) 3.3.4.4 Assessment of the overall parameters To assess the overall parameters of the SCRE model, we examined the statistical power and the GoF measure of the model. This study used G*Power 3.1 (Faul et al. 2009) to obtain the statistical power of the model to assess the robustness of the hierarchical SCRE scale. The overall power of the model is 95.8, and the t value is 1.68. The statistical power in this study exceeds the required power (80%) suggested by Cohen (1988). Therefore, the study has adequate confidence in the hypothesized relationships in the model. This study also
30
used AVE and R2 values to estimate the GoF index to measure the overall fitness of the proposed model (Wetzels et al. 2009). The GoF of the model was 0.661, which is large according to Wetzels et al. (2009). Therefore, the fit index for this model is satisfactory.
3.3.4.5 Technical and evolutionary fitness of SCRE Model We argue that our SCRE model is a dynamic capability tool (Eisenhardt & Martin 2000, p. 1118), which organizations can use to improve SCRE. Using the SCRE model effectively calls for the development of and allegiance to a process (and hence a unique path to transform the organization) and the identification of a supportive “resource configuration” (a unique position) (Teece et al. 1997). As Eisenhardt and Martin (2000, p. 1108) suggest, the SCRE model has both “communalities” and “idiosyncrasies”. For example, the three basic dimensions (proactive, reactive and supply chain design) and twelve sub-dimensions are the unique features (commonalities) of the SCRE model. However, their measurements may vary depending on the organizations, thus revealing the idiosyncrasies of the SCRE model. Our SCRE model can also be assessed using the “technical” and “evolutionary” fitness criteria of dynamic capability theory (Teece 2007). Technical fitness refers to “how effectively a capability performs its intended function” (Helfat et al. 2007, Leiblein 2011). We argue that the GoF of the SCRE model satisfies the technical fitness criterion. As noted earlier, the GoF of the SCRE model is 0.661. The literature suggests that this value is sufficiently large (Wetzels et al. 2009); therefore, the SCRE model is a “technically fit” scale for measuring SCRE capabilities. Hence, our SCRE model adequately satisfies the technical fitness criterion. Evolutionary fitness refers to “how well a dynamic capability enables an organization to make a living by creating, extending, or modifying its resources” (Helfat et al. 2007; Teece 2007, Leiblein 2011). Pohjola and Stenholm (2012) state that the recent literature has mostly used “performance” as the measure of the evolutionary fitness of
31
dynamic capabilities. We thus propose using an increase in SCP and a decrease in OV as a measure of organizational performance based on the successful implementation and practice of the SCRE model. The results above suggest that the SCRE scale positively influences SCP (β = 0.703, t = 19.82) and negatively influences OV (β = -0.615, t = 14.36) (see Figure 2). Hence, our SCRE model also adequately satisfies the evolutionary fitness criterion.
3.4. Scale generalizability To provide evidence of the generalizability of the SCRE scale, a replicative study with organizations from diverse industries is essential. In this regard, we conducted study 3 to re-examine the CFA models using responses collected from 207 business executives from different manufacturing industries in which SCRE is an important issue. Table 16 shows the profile of the respondents in study 3. (Table 16 about here)
3.4.1 Sample and data collection In study 3, the same instrument was used to collect data from executive MBA students at five universities in Bangladesh. The students who were executives in manufacturing and responsible for supply chain functions were selected for the survey. The sample students were located using the database of current students of the universities. A total of 207 completed questionnaires were collected from 231 students. The respondents cover many industries, including apparel (30.4%), garment accessories (8.2%), pharmaceuticals (11.6%), footwear and leather products (7.25%), steel (10.6%), plastics (3.4%), jute (1.3%) and others (10.15%). As a whole, the survey respondents comprised of a diverse sample that lends itself well to a replicative study (see Table 16).
32
3.4.2 Data analysis The replicative study results exhibit desired psychometric properties, as all the item loadings corresponding to first-order constructs were greater than 0.7 and significant at p < 0.01 (except FLX7, i.e., new product development, and CRI2, i.e., critical distribution centre). All AVEs and CRs exceeded the minimum thresholds of 0.5 and 0.7, respectively. The results are also consistent with the measurement model results from study 2. The results further show that SCRE had a strong association with supply chain proactive capability (β = 0.892, t = 87.52), supply chain reactive capability (β = 0.876, t = 84.9) and supply chain design quality (β = 0.892, t = 95.34). Furthermore, supply chain proactive capability, reactive capability and design quality explain 88.7%, 91.6% and 85.2%, respectively, of the overall SCRE variance (see Figure 3). These results thus provide further evidence of the reliability and operational nature of the proposed scale developed in this study to measure SCRE in a wide range of industries. The replicative study results also show satisfactory results for the predictive validity of SCRE with regard to improving SCP and mitigating operational vulnerabilities. Figure 3 shows that all the predictive path loadings are significant. Overall, the results are extremely encouraging in terms of scale generalizability. (Figure 3 about here) 4. Discussion and implications 4.1 Implications for theory Rooted in the DCV, building on previous research, and filling in gaps in the existing literature, the findings of this study make several contributions to the supply chain literature. This study introduces a hierarchical model of SCRE. The validated SCRE measurement scale addresses the existing lack of knowledge on resource specificity and the measurement of 33
dynamic capabilities to combat the challenges associated with environmental uncertainties in the supply chain. The DCV postulates an accumulation of resources and capabilities to combat challenges at the organizational level in tumultuous times. However, the impact of environmental challenges is no longer confined within the boundaries of an organization; instead, it is spread across the entire supply chain. In this study, we presume that organizations’ supply chains need both proactive and reactive forms of dynamic capabilities to develop resilience against disruptive events along their supply chains. We thus extend the scope of the DCV from organizational boundaries to the entire supply chain. Studies using the RBV, including the DCV, fall short of identifying processes, resources and paths that increase competencies during environmental uncertainties along the supply chain. Our study addresses process and resource specificities at the supply chain level in the event of turbulence. Thus, the empirically validated measurement model of SCRE extends the DCV in terms of resource specificity and measurement in the supply chain to combat challenges arising from environmental uncertainty. Our research also contributes to the empirical aspect of the DCV by assessing the SCRE model through the “technical” and “evolutionary” fitness criteria of the DCV. We have justified that the GoF of the SCRE model is equivalent to “technical” fitness, while the predictive validity of the SCRE model (to improve organizational performance) is equivalent to the “evolutionary” fitness of the DCV. Using the DCV as the theoretical foundation, this study thus enhances the body of knowledge in the SCRE literature in particular and the risk management literature in general. Our study also expands and extends the scope of the recent literature on SCRE highlighted in the literature review section 2.1. As noted earlier, the primary research gap is the lack of a comprehensive measurement scale of SCRE based on strong theoretical underpinnings. Our study considers resilience to be a dynamic capability, and we have taken 34
an alternative approach to offer a multidimensional SCRE measurement model. This study thus extends and expands earlier studies on SCRE in a comprehensive way.
4.2 Implications for practice The implications of this research are significant for supply chain managers, specifically those in the apparel industry in Bangladesh and elsewhere. The findings suggest that supply chain managers take proactive approaches towards resilience, design a supply chain that can reduce vulnerabilities, and develop reactive capabilities to respond and recover quickly from vulnerabilities. Our findings validate that SCRE is a critical success factor for SCP improvement. Firms that want to improve their performance need to constantly assess the supply chain design quality and the proactive and reactive approaches to combating supply chain vulnerability. In addition, managers can use the proposed scale as a diagnostic tool to identify areas that require specific improvements. In fact, supply chain managers in the apparel industry will be equipped with knowledge of the factors required to ensure resilience in the supply chain. Supply chain practitioners should convince top management of the paramount importance of proactive approaches (e.g., supply chain readiness, flexibility, reserve capacity, integration, efficiency, market strength, and financial strength) and reactive approaches (e.g., the ability to respond and recover to manage supply chain vulnerabilities). Notably, the proposed SCRE scale introduces a new construct, supply chain design quality, which has significant managerial implications. Supply chain managers should focus on improving supply chain design quality by paying careful attention to supply chain density, complexity and criticality to reduce supply chain vulnerability. Our study will assist supply chain managers in making decisions regarding multi-sourcing versus single sourcing, a focus on a few markets versus the diversification of market, the geographical distribution of production facilities versus production in a concentrated area, centralized distribution versus 35
decentralized distribution, multimodal transportation options and other issues related to supply chain design that seeks to overcome supply chain vulnerabilities. Leveraging the supply chain network design to overcome vulnerabilities is crucial for supply chain decision makers. Our study thus assists supply chain managers in strategizing and deciding on the competencies developed to address environmental volatility. More specifically, the proposed model is expected to elucidate matters so that apparel supply chain members can overcome existing vulnerabilities and achieve sustainability in their supply chains. 4.3 Limitations and future research directions Some limitations of this study are worth noting here. This research adopts a crosssectional design to investigate the phenomenon of SCRE at a particular time. A longitudinal research design could capture the effects of SCRE on supply chain vulnerability in the long run. Thus, a longitudinal focus is recommended for future studies. This research was conducted within a specific industry (apparel) in one country (Bangladesh). Our respondents are immersed in Bangladeshi culture, which is characterized by high power distance and high in-group collectivism (House et al. 2004). Hence, our data will reflect the national cultural bias. Replications in other contexts would increase confidence in the research model. Further assessing the generalizability of the SCRE scale developed in this study to other business environments, for example, testing the scale in other nations, would be worthwhile. The range of variables in our SCRE model has been contextualized for a specific country. As such, our variables should be adapted via field studies to contextualize them in other contexts or countries. Future research might also be conducted to investigate the antecedents and consequences of SCRE. For data analysis, a formal ex-post common method bias test should be performed using an ideal CFA marker variable (Williams et al. 2010). Although the results of our study show that SCRE has a positive influence on SCP, SCP is a multidimensional construct that may be measured in a number of ways, including 36
sourcing, operational and distributional performance (Gunesekaran et al. 2004). Therefore, in future studies, exploring the complexities of the relationship between SCRE and alternative dimensions of SCP would be useful.
5. Conclusions Despite the publication of a few studies on SCRE, a valid and reliable scale for measuring SCRE was still lacking. This study thus developed and validated a scale for measuring SCRE. The scale evaluation by PLS path modelling confirmed the scale’s adequate psychometric properties. We have also evaluated our SCRE model in terms of the “technical” and “evolutionary” fitness of dynamic capability theory. To this end, this study makes an important contribution to the literature. Although the SCRE scale has been assessed and validated in the context of the apparel industry in Bangladesh, it can be adapted for other industrial sectors in other countries with appropriate contextualization via qualitative studies.
