Software maintenance continues to be among the most critical issues facing all software development organizations. Developers are facing increasing demands for new software applications while at the same time having to devote sizable resources to maintaining existing applications. It seems that software developers organizations will reach steady-state when all available resource are devoted to software maintenance. Increasing the productivity of software developers and increasing the quality of systems produced is certainly a high priority in development organizations however, software maintenance productivity seems to be at least as important but not eagerly addressed. Software maintenance has been reported as containing 70-80 of the total software life cycle costs. In the federal government software maintenance is reported to cost an estimated 5 billion. In a summary of 75 major companies, 53 of the total software related activities is in maintenance. In a survey conducted by IBM, over 80 of data processing resources are allocated to maintenance. Even a small increase in productivity in software maintenance will have a dramatic impact on overall data processing costs.
