Abstract
Business architectures are models that describe the business entities, their relationships, their dynamics, and the rules that govern their interaction. these rules are usually called business rules. A major challenge in developing effective business architectures is to define and implement business rules effectively so that the architecture can be adapted whenever new requirements evolve. Current approaches that address business rules do not provide a balance between effective management and reuse of the business rules within the architecture. In this paper, we discuss current solution to manage business rules, and then we propose a enw approach for developing business architectures and their business rules. The proposed approach allows for both managing and reusing business rules. The approach is demonstrated through the means of a case study.
