A redefined software life cycle model for improved maintenance
Torbjørn Skramstad, M.K. Khan · 2003
Software maintenance has been considered the postdevelopment phase of the software life cycle model. The authors suggest however, that maintenance should be integrated into all phases rather than being a separate stage. They propose a redefined software life cycle model with respect to software maintenance. The maintenance phase is seen as a miniature development cycle. In maintenance, a need is identified, it is analyzed, the existing system is understood, and the modifications are implemented. The contemporary maintenance approaches such as re-engineering and reverse engineering are also discussed in the context of the proposed life cycle model.>
