    A model for the evaluation of location based services in South Africa based on soft systems methodology and the process-outcomes model
    (2005) Wiid, Sean; Barry, Michael
    The increasing pervasiveness of technology has led to questions concerning the contribution and value of technology, and to what extent a particular innovation, invention, product, theory or technological development benefits society. The attempt to answer these questions has led to the development of evaluation methodologies to provde a structured approach to this process of inquiry. In most cases, evaluation methodology can be classified as either fundamentally holistic or reductionist in its approach. This dissertation argues that both holistic and reductionist thinking need to be applied to the evaluation of complex phenomena, and develops theory in order to achieve this. In the context of evaluating Location Based Services (LBS) in South Africa, a conceptual framework was developed to combine the holistic, systems thinking apporach of Soft Systems Methodology (SSM) and the reductionist approach of metrics and the Process Outcomes model.
