The need and desire for a Modeling and Simulation Body of Knowledge (M&S BoK) Index has been communicated by simulation professionals and addressed by the SimSummit organizational members. Early prototypes have been developed to demonstrate potential features. A set of requirements is being specified to support development of a knowledge management system to support the M&S BoK Index. This paper proposes a realistic roadmap for implementing the M&S BoK Index using iterative refinement. The crawl/walk/run strategy recommends leveraging currently available web applications to support early versions. Recommendations are provided for implementing the technical solution, encouraging content development, obtaining resources to populate and manage content, and cultivating the M&S community of practice to use and continually improve the M&S BoK Index product in the context of an open source collaborative enterprise.
