摘要

需求、规格说明和程序是由它们所关注的现象来区分的。需求是关于应用领域的现象，描述了机器需要实现和维护的领域的属性。应用程序领域是非正式的，在描述它和对它进行推理时都遇到了严重的困难。需求是复杂的，所以它们必须被分解。分解基于对简单子问题的识别，以问题框架为特征。

Problems and requirements [software development]

Requirements, specifications, and programs are distinguished by the phenomena they concern. Requirements are about phenomena of the application domain and describe properties of the domain that the machine is required to bring about and maintain. The application domain is informal, and serious difficulties are encountered both in describing it and in reasoning about it. Requirements are complex, so they must be decomposed. Decomposition is based on the recognition of simple subproblems, characterised by problem frames.
