A systematic approach to information systems development—II problem and data oriented methodology

摘要

We have in two articles described the ISAC approach to information systems development. The purpose of the first article was to give an introduction and overview of this approach and to describe change analysis, the development area that precedes information systems development. Information systems development consists of analysis, design and realization of information systems. In the ISAC approach we divide analysis and design of information systems into the following four areas: 1.(1) Activity studies,2.(2) Information analysis, (Problem oriented work);3.(3) Data system design,4.(4) Equipment adaptation, (Data oriented work).The purpose of this second article is to describe each of these four areas in the same manner as we described change analysis in the first article. We then show how these different areas are related to each other in a summary. The article ends with short discussions about the effects of information systems development and how to learn more about the ISAC approach.
