An Organization's success and growth are increasingly becoming dependent upon how efficiently the Business Processes are managed. Knowledge Management and Organizational Memory have become critical components in the management of Business Processes. As, the Business Process Managers, Participants and End Users are dependent upon information and knowledge from myriad sources, thus their ability to proficiently access, use and generate new knowledge from existing knowledge has become quite vital. Organizations today work as an interconnected web of their Business Processes. Thus to ensure success, to garner the enhanced organizational capabilities and to have sustain performance improvements, they should incorporate knowledge-sharing among different teams. We present a model, based on Shared Group Topic Map approach which uses these concepts and illustrate its use by way of supporting a group search implementation. The design, implementation and example scenario of this system are given and explained.
