2 BMM and BPMN on the CIM level ASPECT LEVEL Information Service Process Rules Events Organization Goals NFA CIM BPMN BMM CIM2PIM PIM PIM2PSM PSM 3 Business Motivation Model The Business Motivation Model (BMM) is a meta-model of the concepts essential for business governance. underlying principle is Businesses are driven, not by change, but by how they decide to react to change vocabulary for governance influencer assessment business policy strategy tactic goal Governance Governance is necessary for the successful adoption of SOA partly because of the cross-organizational nature of SOA where service funders, designers, implementers, maintainers, or consumers are not located in the same organization, business, IT department, LOB, division, or enterprise. 2

3 two major areas of the Business Motivation Model The first is the Ends and Means of business plans. Among the Ends are things the enterprise wishes to achieve for example, Goals and Objectives. Among the Means are things the enterprise will employ to achieve those Ends for example, Strategies, Tactics, Business Policies, and Business Rules. The second is the Influencers that shape the elements of the business plans, and the Assessments made about the impacts of such Influencers on Ends and Means (i.e., Strengths, Weaknesses, Opportunities, and Threats). Simplified View of BMM Means What you decided your Enterprise should do References to Courses of Action Ends Business Operations - Business Processes - Business Rules - Responsibilities - Resources - Services Directives Influencers Govern the Courses of Action Assessments Telecom Informatics BMM and GRC 6 Model 3

10 BPMN example EPF Composer EPF Composer is a tool platform for process engineers, project leads, project and program managers who are responsible for mainteining and implementing processes for development organizations or individual projects Aims to: provide for development practitioners a knowledge base of intelectual capital that allows them to browse, manage and deploy content. provide process engineering capabilities by supporting processe engineers and project managers in selecting, tailoring, and rapidly assembling processes for their concrete development process. Note: This is also a Business Process for Software dev. 10

13 BPMN requirements Core Set of Diagram Elements The core set of modeling elements enable the easy development simple Business Process Diagrams that will look familiar to most Business Analysts (a flowchart diagram) 13

14 Complete Set of Diagram Elements, Events An Event is something that happens during the course of a business process. These Events affect the flow of the Process and usually have a trigger or a result. They can start, interrupt, or end the flow. Complete Set of Diagram Elements, Activities, Cont. A Sub-Process can be in an expanded form that shows the process details of the a lowerlevel set of activities. 14

15 Complete Set of Diagram Elements, Gateways Gateways are modeling elements that are used to control how Sequence Flows interact as they converge and diverge within a Process. If the flow does not need to be controlled, then a Gateway is not needed. BPMN Diagram elements 15
