Chapter 10 Role modeling Overview The concept of roles is utilized either explicitly or implicitly in various areas related to the specification of enterprise automation needs. Unfortunately there is no general agreement as to the definition or characteristics of a role. That ambiguity results in considerable confusion as to how to specify and use roles effectively especially in the development of process maps. The purpose of this chapter is to present a comprehensive discussion of roles and their use in the enterprise. Because of the close identification of the term role with stage plays and movies the tendency is to transfer that association to the understanding of roles in the enterprise. While the analogy is close there are some subtle differences that if not recognized and accounted for can greatly confuse the concept and hinder the acceptance of roles as a useful entity. For that reason all the terms used here are carefully motivated and defined. That allows deviation as needed from the popular notion of the term. In addition questions that arise from the current confusion in using roles . is customer a role are addressed and answered. Roles are automation assets and as such all the concepts developed in Part I apply. This chapter explicitly addresses many of those considerations. However even if a specific aspect is not explicitly addressed in this discussion it still is important in a design and development situation to explicitly consider all the management system functions. Basic definitions Because a role must exist in an environment that utilizes other ambiguous terms it is necessary to define a number of those terms for an understanding of the overall environment involved. Because there is a close analogy to the stage and movies examples are used that exploit that association as long as the analogy does not become unduly strained.
