Characteristics of Application Software Maintenance.

Abstract

Maintenance and enhancement of application software consume a major portion of the total life cycle cost of a system. However, the area has been given little attention in the literature. To analyze the problems in this area a questionnaire was developed and pretested. It was submitted to 120 organizations. Respondents totaled 69. Responses were analyzed using the SPSS statistical package. The results of the analysis indicate that (1) user demands for enhancements and extensions constitute the major perceived problem area, (2) problems of a management nature are viewed in general as more significant than technical problems, (3) the use of technical productivity aids remains limited; however, maintenance programmer productivity is not considered by management to be a major problem.
