An investigation into software maintenance-perception and practices

The authors present the results of a survey conducted on the perceptions and practices in software maintenance in five major companies in the United Kingdom. It is clear from the study that software maintenance is undergoing a significant transformation, in particular, in terms of its image, its relationship with users, and the nature of software maintenance tools required. The image of the software maintenance task appears to be changing from one which is dull, passive, and isolated to one which is reactive, responsive, and vital to the business. Maintenance departments are becoming more accountable to user departments and are developing a market orientation. The study found little use of existing software maintenance tools and identified a need for support technology which will facilitate communication among users, developers, and maintenance staff. The authors present the background to the investigation, the procedures followed, a summary of current practice, and an analysis of the problems and trends identified
