Flexibility: A Key Factor to Testability

Abstract

Testability is an important software quality factor that is ineffective if it is not available at an early stage in the development life-cycle. It becomes more essential in the case of object oriented design. Flexibility is an important key factor to testability analysis and measurement for delivering high class testable and maintainable software. Flexibility is a criterion of crucial significance to software developers, designers and the quality controllers. It constantly guides and supports to avoid wastage of resources as well as enable the designers for continuous improvement in the development process. Flexibility is concerned with building high quality and reliable software within the constraints of cost and time. It greatly influences cost, quality and reliability at software evolution process. Despite the fact flexibility is vital and highly significant aspect for software development processes, it is poorly managed. This paper focuses the need and importance of flexibility early at design phase. A model has been proposed for flexibility measurement of object oriented design by establishing multiple linear regression. Finally the proposed model has been validated using experimental tryout.
