Logical Soft Systems Modelling for Information Source Analysis

It has been argued that the Conceptual Models used in Soft Systems Methodology (SSM) are logically inadequate for some of the purposes, notably information system design, for which they are used. In a series of theoretical papers it has been argued that this shortcoming could be rectified by producing logically enhanced versions of the SSM models. The paper describes the use of these models for the identification of information requirements to support planning in a marketing department of a Hong Kong telecommunications company. The project demonstrates that the models are not, as has been suggested, too complex to be used in client led modelling.
