Abstract

This paper is concerned with the economical maintenance of large software products. It examines the software maintenance process and outlines a framework, based on cost-benefit, within which changes to the maintenance environment affecting future maintenance productivity can be evaluated. It also looks at the rationale for the recommendations that are made. The recommendations include the formation of a team charged with overseeing the maintainability of the products and the implementation of certain protocols for maintenance that rigorously incorporate documentation maintenance. The paper is based on the authors ' experience with a large software product, and contains product-specific recommendations.
