An important premise of most of the contemporary methods for developing Software and Information Systems is that a good understanding of the application domain is essential for a comprehensive definition of its requirements. However, when these methods are applied to the enterprise context, it is very unclear what an application domain means. To solve this problem, we elaborate the notion of business system and propose a method based on such notion for modeling application domains of Enterprise Information Systems (EIS). This method helps EIS development teams to get comprehensive knowledge about EIS application domains. This knowledge is expressed in terms of the fundamental concepts of a business system: goals, technologies, business rules, business processes, business objects, actors, job structure, and events. The method is described in terms of three methodological components: a product model, a process model, and a team model. This structure facilitates the explanation, understanding and application of the method.
Business modelling is a central activity to many different areas, including Business Process Reengineering, Organisational Development, Enterprise Modelling & Integration, Business Process Management and Enterprise Application Integration. It is well known that the business domain is not easy to understand neither to represent even for specialised people. The success of most of the contemporary methods for modelling Business Organisations is strongly associated with the level of understanding that the modelling team can attain about the specific situation being modelled. This understanding is directly related with the degree of modelling experience that the team has, as well as their ability to work with the techniques and tools prescribed by a specific method. Nowadays, most of the existing business modelling methods is concentrated in what the business concepts are and how to represent them. But, they lack of process guidance, which is needed to help the team through the modelling process. We elaborated the method BMM for modelling business application domains that provides working guidelines for the modelling team. This method, based on method engineering concepts helps teams to, not only, get a comprehensive knowledge about the business domain being modelled, but also, about the process of modelling the domain itself. This paper concerns with the representation of the process of modelling a business by using decision oriented process model formalism. The main contribution of our work is a set of roadmaps that contains the knowledge associated with team member's modelling experience in business modelling and EIS development. This knowledge arises from several case studies.
