Abstract

Traditional systems analysis prescribes the definition of problems in terms of a 'means-end' schema, which assumes that the problem can be perceived as a search for an efficient means of achieving declared objectives or meeting pre-defined goals. This is a framework which is generally associated with 'hard' systems thinking. The approach, thus, involves clearly defining the need to be met, and developing models of alternative systems which could meet the defined need. The concern of 'hard' systems approach is therefore basically 'how-to-do- it', because 'what-to-do' has already been taken care of. However, ill-defined, unstructured problem situations as found in many organizations today require a more broad-minded approach that could lead to decisions on attempts to improve both the 'what' and 'how'. This, in principle calls for a switch to 'soft' systems thinking which should serve to free the analyst from the traditional restriction mentioned above. This is the main course taken in this research which is conducted on a university library's circulation control system, where the management has expressed the wish to employ the use of modem information technology, but was not certain whether and how that could lead to improved efficiency. Using the 'soft' systems methodology as an intervention tool, the circulation department's information requirements have been addressed, raising a number of issues regarding the far- reaching implications of developing a computer-based information system by the inclusion of a data modelling technique at the 'other systems thinking' stage.
