The views of the Mark Westcombe, L Alberto, and Duncan Shaw, on the factors that delayed development of problem structuring methods (PSM) till 2000 are presented. The delay was due to the failure of researchers in talking an active role in developing the theory and application of problem structuring. Many PSMs relies on the same basic methods proposed by the originators, only supporting the methods with computer software as a sign of development. New methods had not been integrated into the literature which suggested that the latest development by academics was also delayed. The explanations offered for the pre-2000 lack of method-specific research include that the originators might not have had interest in systematically evaluating their own technique and on the action research context in which PSMs were applied require the researchers to undertake roles of consultants and investigators.
