3 7.2. Business vision view A business vision view is a model of the business in terms of general vision, the business language and the business motivation Vision statement A vision statement is a textual document expressing the main idea of the business (at the current time and in the future) An example We should be the leading supplier of office equipment and supplies. We should offer customers attractive solutions and good value for their money. By not going through a retailer, we cut the sales expenses. Integrating our sales processes with our customers purchase processes results in highly efficient communication and delivery. To be able to integrate these processes, we must provide several interfaces, such as Internet, , FTP, telephone, and fax. We can integrate further by offering additional services such as inventory tracking and automatic purchasing. [Source: Eriksson, Penker] Dr. Witold Rekuć Business Object Modeling 173

8 7.3. Business process view A business process view is a model of the business in terms of processes, interconnections between them and goals. It consists of: Process models with goals and resources flow, Process models with business events and control flow, Assembly line models Dr. Witold Rekuć Business Object Modeling 178

12 7.4. Business structure view A business structure view is a model of the business in terms of resources, including information and organization. It consists of: Resource class model Information class model Organization objects model Dr. Witold Rekuć Business Object Modeling 182

13 Resource class model represents resources physical or abstract things that are essential entities of the business modeled. What is the difference between the conceptual model and the resource model? Dr. Witold Rekuć Business Object Modeling 183

14 Information class model represents information about physical or abstract things used in the information system. What is the difference between the resource model and the information model? Dr. Witold Rekuć Business Object Modeling 184

15 Organization object model represents organizational units and their relationships. Dr. Witold Rekuć Business Object Modeling 185

16 7.5. Business behavior view A business behavior view is a model of the business in terms of changes. It consists of: State-chart (machine) models Sequence or collaboration models Process interaction models Dr. Witold Rekuć Business Object Modeling 186

23 Summary 1. One can look at business from four perspectives called views: business vision, business process, business structure, business behaviour. 2. The business vision view defines a vision, a language and motivation of the business (class and object models). 3. The business process view determines processes, their relation to the motivation and the resources (process models). 4. The business structure view is model of the resourses structure (class and object models). 5. The business behaviour view shows changes (state machines, sequence and process interaction models).
