Abstract
Until a few years ago the area of software maintenance was largely ignored. Interest has increased recently for three reasons. First, the increased number of systems, combined with the increased volume of enhancement and maintenance, has restricted resources available for new development..Second, there has been a growing awareness that tools and aids that assist in developing systems may have little effect on operational systems. Third, the management of information systems has come under increasing scrutiny in terms of costs and resource utilization. In this paper some of the major issues that surfaced during several extensive operational software studies are highlighted. These studies have raised significant questions about the roles of the users in operations and maintenance, the management of maintenance, and the kinds of tools and techniques that are needed for maintenance.
