Re-Engineering Software Systems in the Department of Defense Using Integrated Computer Aided Software Engineering Tools.

摘要

The Department of Defense (DoD) is plagued by severe cost overruns and delays in developing software systems. Existing software within DoD, some developed 15 to 20 years ago, require continual maintenance and modification. Major difficulties arise with maintaining older systems due to cryptic source code and a lack of adequate documentation. To remedy this situation, the DoD is pursuing the integrated computer aided software engineering (I-CASE) procurement as a means to improve DoD's development and maintenance of software systems. This study focuses on the concepts and theory behind software re-engineering. In particular, it studies the current state of I-CASE technology, and the feasibility of re-engineering existing software systems for migration to an I-CASE environment.
