Information systems development methodologies:
a classi® cation according to problem situation

Information systems development methodologies are frequently classi® ed according to themes or features.
Yet potential users are more concerned with the situations in which different approaches are appropriate.
In this paper, ® ve problem situation types are identi® ed: (1) well-structured problem situations with a well-
de® ned 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 classi® cation 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.
