This Master''s thesis concerns the problematic issue of tailoring knowledge management systems through application of Soft Systems Methodology (SSM) and prototyping.

The objective is to explore how the process of tailoring knowledge management systems can benefit from using SSM and prototyping.

In collaboration with WM-data, we conducted an in-depth SSM analysis followed by a series of experiments using prototypes. The prototypes were developed in order to validate the relevance of the underlying system ideas through actual use by the end-user.

Our main contribution is a model comprising an analytical mode of operation (SSM) and an experimental mode of operation (prototyping). We have found that the two methodologies compensate each others weaknesses well and together suit the needs for tailoring knowledge management systems.
