Abstract

To understand developers' typical tools, activities, and practices and their satisfaction with each, we conducted two surveys and eleven interviews. We found that many problems arose because developers were forced to invest great effort recovering implicit knowledge by exploring code and interrupting teammates and this knowledge was only saved in their memory. Contrary to expectations that email and IM prevent expensive task switches caused by face-to-face interruptions, we found that face-to-face communication enjoys many advantages. Contrary to expectations that documentation makes understanding design rationale easy, we found that current design documents are inadequate. Contrary to expectations that code duplication involves the copy and paste of code snippets, developers reported several types of duplication. We use data to characterize these and other problems and draw implications for the design of tools for their solution.
维护心智模型:对开发人员工作习惯的研究
为了了解开发人员的典型工具、活动和实践以及他们对每个工具、活动和实践的满意度,我们进行了两次调查和11次访谈。我们发现,许多问题的出现是因为开发人员被迫投入大量精力,通过探索代码和打断队友来恢复隐性知识,而这些知识只保存在他们的记忆中。与期望的相反,电子邮件和即时通讯可以防止面对面的中断所造成的昂贵的任务切换,我们发现面对面的交流有很多优点。与期望文档使理解设计原理变得容易相反,我们发现当前的设计文档是不充分的。与期望的代码复制涉及代码片段的复制和粘贴相反,开发人员报告了几种类型的复制。我们使用数据来描述这些问题和其他问题,并为解决这些问题的工具设计提供启示。
