Information Systems Development Methodologies: A Classification According to Problem Situation
本文识别了五种问题情境类型，将典型信息系统开发方法论归入各组，并讨论了分类的优缺点，指出多数项目属于复杂问题情境，详细介绍了适用于该情境的Multiview方法。
Information systems development methodologies are frequently classified according to themes or features. Yet potential users are more concerned with the situations in which different approaches are appropriate. In this paper, five problem situation types are identified: (1) well-structured problem situations with a well-defined problem and clear requirements, (2) well-structured problem situations with clear objectives but uncertain user requirements, (3) unstructured problem situations with unclear objectives, (4) situations where there is a high user interaction with the system and (5) complex problem situations. Typical information systems development methodologies are placed in each of these groups. Some strengths and weaknesses of this classification are discussed. One conclusion is that most projects will fall within the category of complex problem situations, for organizations (and therefore their information systems needs) are invariably complex in terms of the human and social aspects at least as much as any technological ones. The Multiview approach is discussed in more detail because the authors claim it is suitable for such situations.
