10 Domain Challenges Objectives Definitions Main Objectives: To make process definitions explicit with the use of models To reduce the complexity of changing process models DSM-07 Slide 6

11 Domain Challenges Objectives Definitions Main Objectives: To make process definitions explicit with the use of models To reduce the complexity of changing process models DSM-07 Slide 6

12 Key Definitions Problem Domain Domain Challenges Objectives Definitions Target Process A target process (TAP) is a business process selected for improvement inside an organization. DSM-07 Slide 7

13 Key Definitions Problem Domain Domain Challenges Objectives Definitions Viewpoint A viewpoint [10] is the perspective from which a particular stakeholder interacts with a TAP in terms of the concerns relevant to him. DSM-07 Slide 8

14 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation Our Strategy is organized in the following way 1 Target processes definition using process models 2 Viewpoint definition using a Domain-Specific language 3 Target process and Viewpoints Integration DSM-07 Slide 9

15 1. Target Process Definition 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation We defined a Business Process Metamodel Based on the Business Process Modeling Notation (BPMN) specification proposed by the OMG [1] DSM-07 Slide 10

16 2. Viewpoint Definition 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation We designed and defined the AspectViewpoint Language A Domain-Specific Aspect Language (DSAL) To create Viewpoint models (Concerns) Uses the Workflow Control Patterns [11] as part of its vocabulary DSM-07 Slide 11

17 2. Viewpoint Definition (Cont.) With AspectViewpoint we can express 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation Where the viewpoint affects the target process How the viewpoint modifies the target process DSM-07 Slide 12

18 2. Viewpoint Definition (Cont.) With AspectViewpoint we can express 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation Where the viewpoint affects the target process How the viewpoint modifies the target process DSM-07 Slide 12

28 1. Target Process Models 2. Viewpoint Definition 3. Target Process and Viewpoints Integration 4. Implementation 5. Experimentation 5. Experimentation We work with a Software Development Company Technical solution process area - CMMi level 1 (Continuous Representation) We created a Target Process model to represent this process The objective was to modify the process to achieve level 2 The test cases in this scenario showed how the generic practices (concerns) were easily modeled using our viewpoint language After the integration of the TAP and the Viewpoints we obtained the expected processes. DSM-07 Slide 18

29 Conclusions Conclusions 1 We reduced the complexity of changing process models We provided a Domain-Specific model for representing stakeholder s concerns In a Modular and non-intrusive way 2 Stakeholders and process designers improved their communications using the AspectViewpoint language DSM-07 Slide 19
