Formalizing and automating component reuse

Engineering Information Abstracts (Part II) zations, they do emphasize different activities and the different methods available of controlling and improving information systems quality are restricted to those commonly used in the three different fields. More flexible methods are needed to facilitate successful quality improvement programs. ŽAuthor abstract. 19 Refs.

Six articles that give a context oriented overview of the IS quality are presented. These articles include: the concept of ŽIS. quality and putting it in its organizational and historical context; the organizational hierarchy of the IS quality group SOftware Library Evolution ŽSOLE. quality model which comprise of business quality, use quality, and IS work quality; and the maintenance of IS quality during the whole system life-time. 9 Refs.

Six Sigma methodology, which tries to increase quality through systematic process improvement, was applied to a sample of usability data. The results of this effort found that usability defects were highest in those products where there had been minimal involvement

of the User Interface staff and usability defects were most dramatically reduced by using a systematic approach to usability Ži.e., the user interface design process.. When presented to upper management, the net effect of this study was a raised consciousness in the company that usability defects are very controllable, a policy statement issued that future development efforts would include the user interface design process, and a commitment for increased resources for the User Interface team.

Corporate Source: Michigan State Univ, East Lansing, MI, USA Conference Title: Proceedings if the 1997 IEEE 9th IEEE International Conference on Tools with Artificial Intelligence Conference Location: Newport Beach, CA, USA Conference Date: 19971103-19971108 Source: Proceedings of the International Conference on Tools with Artificial Intelligence 1997. IEEE, Piscataway, NJ, USA,97CB36147. p 94-101 CODEN: PCTIFX ISSN: 1063-6730 Publication Year: 1997 Abstract: Using existing components to construct software systems has significant potential to improving software productivity and quality. A key problem in software component reuse is the selection of appropriate components for satisfying at given requirement. In this paper, we define a component interface generality relation that provides a foundation for component selection. This generality relation, represented in terms of formal specifications, precisely captures the semantic obligations for an existing component to satisfy the requirements of a target system. The formal specifications facilitate the Žsemi-. automatic determination of the generality relation. We show how this generality relation has been used to determine the reusability of software components in a software architecture-based reuse and integration environment. ŽAuthor abstract . 13 Refs.
