In an empirical analysis of sixty-five software maintenance projects in a large IBM COBOL transaction processing environment, the impacts of correctable software complexity upon project costs were estimated. Module size, procedure size, and the use of complex branching were all found to significantly affect software maintenance costs. It was estimated that projects involving maintenance of syst...

Understanding and Controlling Software Costs

Section 2, the main portion of the paper, discusses the two primary ways of understanding software costs. The "black-box" or influence-function approach provides useful experimental and observational insights on the relative software productivity and quality leverage of various management, technical, environmental, and personnel options. The "glass-box" or cost distribution approach helps ident...

How to save on software maintenance costs

The cost of software maintenance is rising dramatically and it has been estimated in [1] that nowadays software maintenance accounts for more than 90% of the total cost of software, whereas it was around 50% a couple of decades ago. There are several reasons for this. We can see that software systems become hard to maintain over time, while every day more and more software is being produced. Do...

Development costs and open source software

This paper analyzes the effect of the development cost on an open source software enhancement that is developed by individual programmers in an Internet community. It considers a situation in which each programmer's cost of development is common knowledge but his valuation of the enhancement is his private information, with other programmers knowing about only its distribution. Depending on the...
