应用软件的维护和增强消耗了系统总生命周期成本的主要部分。粗略估计每个类别消耗的总系统和编程资源高达 75-80%。然而，该领域在文献中却很少受到关注。为了分析该领域的问题，制定了一份调查问卷并进行了预先测试。然后将其提交给 120 个组织。受访者总数为 69 人。使用 SPSS 统计软件包对答复进行了分析。分析结果表明：（1）维护和增强确实消耗了系统和编程组总资源的大部分； (2) 管理层倾向于认为维护和增强至少比新应用软件的开发更重要； (3)在维护和提升方面，管理导向的问题往往比技术导向的问题更显着； (4)用户的增强和扩展需求构成最重要的管理问题领域。
Maintenance and enhancement of application software consume a major portion of the total life cycle cost of a system. Rough estimates of the total systems and programming resources consumed range as high as 75-80 percent in each category. 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 then submitted to 120 organizations. Respondents totaled 69. Responses were analyzed with the SPSS statistical package. The results of the analysis indicate that: (1) maintenance and enhancement do consume much of the total resources of systems and programming groups; (2) maintenance and enhancement tend to be viewed by management as at least somewhat more important than new application software development; (3) in maintenance and enhancement, problems of a management orientation tend to be more significant than those of a technical orientation; and (4) user demands for enhancements and extension constitute the most important management problem area.
