Abstract: There is a need to integrate knowledge based systems (KBS) with information systems (IS) technical solutions, which implies that KBS and IS development methodologies should be less isolated from each other. KBS and IS development methodologies are generally examined in terms of their similarities and differences. There is divergence at the feasibility and analysis stages, convergence at the design and coding stages, divergence during testing, convergence at the implementation stage, and divergence during maintenance. There are more similarities than there are differences between IS and KBS methodologies, particularly during the strategic planning stage. It is argued that linking KBS strategic planning to the planning element of an IS methodology will go further towards ensuring that the whole of the business is considered, leading to better integrated IS/KBS solutions. Application selection activities of two well-known KBS methodologies are briefly analysed. We show that these activities, which precede the feasibility study, do not consider the strategic aspects of the use of KBS (and IS in general) in business organizations. It is argued that a KBS strategy should be formulated in relation to the IS strategy and the business strategy, therefore increasing the convergence between IS and KBS methodologies.
