the process of policy dialogue. An example of a new product diversification demonstrates the role of risk analysis in clarifying problem assumptions and in understanding the impact of uncertainty on decision-making. Risk analysis is seen as an adjunct and aid to problem formulation and resolution and not an end in itself.
Risk analysis’ 9’ was originally presented as a useful addition to the range of techniques used in financial evaluations. It was seen as a logical extension to sensitivity analysis3 and a means of explicitly taking account of uncertainty in financial forecasts. Thus, the proposition that risk and uncertainty were more accurately defined by a simulation of input variables was little questioned thereafter. Managements began to adopt some form of this procedure to examine some, if not all, significant investments where doubt existed about the risk levels involved. It was emphasized, however, that in the end managerial judgment would be required in both input estimation and decision. Although this approach was seen by many readers about methodology in to be an argument that was not the main investment appraisal, intention. Rather it was intended that it should be a cautionary note to businessmen to examine the data surrounding an investment proposal in the light of all the pervasive uncertainties in the world of which business is simply one part. Indeed, this message should have been emphasized and amplified as subsequent events have proved. seen as a planning

and thinking process.4 Namely, as an approach for forecast/uncertainty based planning (Stage II/III of Gluck’s four stages of strategic planning) in which an understanding of project risk, cash flow projections and future scenarios is developed. This paper has as its main aim the proposition that risk analysis can help strategic thinking by encouraging constructive dialogue and debate about the In such a dialogue process, risk policy options. analysis is seen as an input for the strategy development process which aids strategy formulation, evaluation, choice and implementation. In this view of the world, there is no distinction between strategic risk analysis and strategy formulation. Rather, analysis and formulation are parts of a policy dialogue process which is iterative, adaptive and flexible. This dialogue involves the consideration by management of problem and formulation through a continual repolicy examination of potential alternative strategies and problem assumptions. In subsequent sections, the role of strategic analysis in strategic problem formulation

evaluation is defined. This role is amplified with an example taken from strategic new product diversification and some conclusions are drawn.
Strategic Risk Analysis and Policy Dialogue The role of strategic risk analysis in policy formulation and choice should be to force hard thinking about the problem under consideration. That is, it should highlight what alternatives should be considered; should examine changing secondary effects and anticipate the nature and extent of the impact of uncertainty for contingency planning. Thus, it is recognized that an initial risk analysis is at problem no more than a first attempt understanding. It should encourage controversy and allow members of the decision-making group to find out where basic differences exist about
1982
problem assumptions, values and uncertainties. This controversy should enable critical comment and review to be obtained, and through policy dialogue force the re-analysis, re-examination and sensitivity testing of the problem solution. Thus, after considerable dialogue, the quality and level of debate about the problem should be improved. This should facilitate compromise and consensus around a reasonable problem solution. An example of the use of strategic risk and analysis follows, and insights gained summarized in the conclusions section.

a series of indicator variables or criteria, rather than in terms of a single rate of return, performance measure such as internal rate of return or net present value.

newly developed synthetic product. (Note: that the example and company are real although some of the chronological and assessment features of the problem have been disguised.) Management was faced with a seemingly attractive product, but was unsure about the longer-term competitive viability of the product. In particular, given the high capital investment requirements, there was concern about the decreasing prices of competitive products and the increasing possibilities of additional entries into the market.

It was decided that a risk analysis evaluation of the new product opportunity should be undertaken. The key assumptions of the model are outlined in Figure 1 and the flow chart for the risk analysis model is shown in Figure 2. An important point to note is that management decided that they wanted the new product opportunity evaluated in terms of

diffuse or ‘spread out’, confirming the proposition that the management team were uncertain about the future and had difficulty in confronting and assessing these future events. Figure 3(b) shows how this risk analysis model handled correlation effects. The figure shows how the procedure works in relation to correlated sales in successive years of the product’s life. In first years sales are sampled from the low range of the distribution, then the model samples a value for second year sales from the second year sales distribution assessed conditional on low sales in the first year. Similarly, if first year sales are in the middle or high range, then the second-years sales value is obtained by sampling the appropriate conditional distribution as shown by the arrows in the figure.

A necessary input for the calculation of these probability profiles was the probability distributions of the important uncertain variables in the decision problem. Figure 3(a) show these assessments for the years 1968 and 1977. It is interesting that the distributions for 1977 are much more INPUT

Figures 8 and 9 show the results of one form of sensitivity testing, that is the examination of the effects on rate of return as a result of percentile changes in each member of the set of uncertain variables. This sensitivity testing showed that the critical factors for success were the size of the synthetic market, the share of the synthetic market the new product is likely to obtain, the sales price of the final product, the variable costs and the financial resources involved in capital investment.

It was decided that attention should be focused very firmly on the objectives underlying diversification moves as well as the portfolio effects on the organization. Further re-analysis was considered necessary to aid formulation and it was felt that, in the meantime, the critical factors should be monitored and re-assessed. Such factors included the size of the synthetic market and environmental influences on the generation of competing products. It was decided, therefore, to postpone an irrevocable policy decision for several months, particularly given the high potential exit costs associated with failure of such a diversification move. In some ways, the greatest benefit of the analysis from its contribution seemed to come to organizational processes in terms of the reduction of controversy and the improvement of communication.

What this sensitivity testing achieved was the confirmation to many members of the management team that it was necessary to look even more closely at this new product decision situation. There was concern both about the realism of the problem assumptions and the influence of contingencies on policy diversifications into synthetic product areas.

risk analysis in the policy dialogue process. First, it was clear that the value of the iterative, cyclic process of dialogue was that it forced a morefoctlsed and of assumptions, scenarios questioning product/market concepts. It was decided, for example, that some extreme ‘what-if’ scenarios related to the growth of the synthetic market should be included in order that the team could examine and challenge project assumptions. Second, the value of sensitivity analysis3 lies in relation to its simplicity and the speed and economy with which it is undertaken. It can quickly highlight crucial uncertain areas and focus attention on contingency planning. It is, thus, a complement and a necessary adjunct to the application of risk analysis. Third, the dialogue process about six performance measures does no more than recognize that there is no single ‘best’ criterion, or set of criteria, by which strategic management of the firm’s strategic diversification should be handled. Rather it encourages all members of the management team to more fully understand policy alternatives before a choice decision had to be made.
Conclusion This strategic dialogue approach, supplemented by risk analysis, should be viewed as supportive of, and complementary to, an earlier paper5 emphasizing the value of risk analysis in the development of strategic thinking. The view put forward in this paper is that a

useful measure of reconciliation amongst the various viewpoints in a management team can be achieved through a continuous policy dialogue involving analyses and assumptions. Risk analysis is presented, therefore, as a useful additional framework for understanding, formulating and resolving illstructured, complex policy and planning problems. Mason and Mitroff (1981, p. 302)6 put it another way : ‘In our view the task of policy, planning and strategy should not consist of attempting to demonstrate the superiority of one approach or framework for all situations but rather of mutual dependency. ... showing their
Whatever methods are used they should always strategic planning aid in challenging assumptions.’
