Using Symbolic Modeling in Business Re-Engineering

Abstract

This paper describes the use of a symbolic modeling tool and a methodology we developed for modeling processes in business re-engineering projects. DECmodel, a symbolic modeling tool, was used to build dynamically activated, working scale models of processes. Models were developed for business, systems, and organizational processes at several levels of detail, and integrated into a large dynamic model. Basic model specification, development, simulation, and animation techniques are discussed. The dynamic models created with this tool were invaluable in validating and communicating process designs, complementing and working in harmony with more traditional, static modeling methodologies. This paper also describes a methodology we have developed for using a symbolic modeling tool for business re-engineering projects. We have documented specific procedures for utilizing process modeling for a whole spectrum of activities ranging from depicting the "as-is" process to brainstorming breakthrough design concepts to documenting functional specifications for MIS implementation teams.
