Abstract
Reusing requirements improves product quality and the productivity of the
development process. This paper investigates how the development of new
requirements can be made more productive through reuse of the experience gained
on similar requirements. This can be facilitated using a component-based reuse
approach supported by a framework. Therefore, the central challenge for this
research work is double: (1) to define a new concept for the requirement
component as the combination of two types of knowledge: reusable knowledge and
knowledge of reuse; (2) to define AFR (Analysis For Reuse) that represents the
capitalization process by opposition to Analysis By Reuse that represents the
process of reuse itself. Finally, we provide a case study related to the
requirements of a hotel system to explain how the first process works. Through
this approach, we use a framework ‘Requirements Repository Framework
(R2F)’ in order to capitalize existing requirements within a repository
for future reuse. We present the results of an experiment with three
second-level student sections that used R2F in their IS240 course project; as
well as with four student groups that used R2F in their respective senior
projects. The objective of this experiment is to measure the usability of the
proposed AFR process.
