An Empirical Evaluation of the Impact of Case on Developer Productivity and Software Quality
基于英国组织软件开发者问卷调查，发现CASE工具提升生产率和软件质量，尤其改善可靠性和准确性，但可能降低效率；收益取决于开发者经验、能力和培训。
This paperpresents the findings of research into the impact of computer aided software engineering (CASE) tools. It is based on a questionnaire survey of software developers in UK organizations. CASE had a positive effect on developer productivity and the quality of applications software. It particularly improved the reliability and accuracy of applications software, though this was sometimes offset by a deterioration in software efficiency. There was little evidence of productivity being ‘traded’ for quality, since developers citing productivity gains also tended to report quality improvements. The extent to which organizations were able to realize the benefits of CASE depended on the experience, competence and training of individual developers. This has significant implications for the selection and training of personnel and the use of consultants. Methodologically, the findings also serve to underline the importance of explicitly taking account of prior development environments, when using retrospective methods to evaluate different software technologies.
