Applying Psychology to Facilitate Participation in Conceptual Modelling

Abstract

Conceptual modelling is a key skill in IS design. It requires substantial expertise, which is largely restricted to IT professionals. Nevertheless, many systems are developed by or with nonexpert modellers, including end users who use products such as FileMaker and Microsoft Access. The results are often disappointing, in part, because of poor modelling. Training would help, but there is also a case for making modelling easier. In this study, ideas from psychology were applied with the goal of making the modelling process easier for nonexperts, particularly by using more understandable model representations. The resulting guidelines can help in formulating modelling techniques for use by nonexperts.
