ADA Reusability Analysis and Measurement
The demand for software has exceeded the industry’s capacity to supply it. Projects are frequently scaled down, delayed or even cancelled because of the time and effort required to develop the software for them. Further, the demand for software will continue to increase in the foreseeable future. Software reuse provides an answer to this dilemma. Although process and tool reuse is common practice, lifecycle product reuse is still in its infancy. Ultimately, reuse of early lifecycle products might provide the largest payoff, however for the near term, gains can be realized and further work can be guided by understanding how software can be developed with a minimum of newly-generated source lines of code.
This paper describes several parallel studies being conducted at the University of Maryland Department of Computer Science which address various related software reuse topics.
One important result of these efforts has been the identification of a set of guidelines which can be used to assist developers to create more inherently reusable software, to select reusable parts from existing software, and to modify existing software to improve its generality and reusability while preserving its functionality. Although the guidelines are written with respect to the development and reuse of systems written in the Ada language, since Ada is the medium for these studies, they apply generally to software engineering.
