2 Theory about Business Processes Definition: A business process is a group of tasks that together create a result of value to a customer. [Hammer96] Its purpose is to offer each customer the right product or service, e.i., the right deliverable, with a high degree of performance measured against cost, longevity, service and quality. [Jacobson et al., 96] Process goals and performance measures are available in process theory BUT: visibility in conceptual Business Process Modeling Languages (BPMLs) is not available! 2

3 Motivation Example Goals? Cycle Time? Quality? Costs? 3

4 Goals of the Extension Current BPMLs [List et al., 2006] do not provide explicit notation elements for process goals and their measures E.g. designer has no possibility to integrate time limits 1. Enhancing the expressiveness one of the most widelyused BPMLs, namely the Event-Driven Process Chain (EPC) and the Business Process Modeling Notation (BPMN) by deriving metamodels for both, 2. Extending their metamodels with business process goals and performance measures to make them conceptually visible. Time Quality Costs Goals 4

5 Contribution of the Extension Modelling of goals and performance measures allow to structure process design, to better understand the broader implication of the process design Performance measures quantify business process goals and thus help to evaluate the process design and the operating process The extended EPC and BPMN make the evaluation criteria for a business process conceptually visible 5

17 Conclusion of the Extensions of EPC and BPMN EPC as well as BPMN... belong to the most well-known languages but both are not able to represent performance measures Developing metamodels of both languages to integrate business process goals and... performance measures This work provides an explicit illustration of the performance measures time, cost, and quality in both languages These extensions... better illustrate the requirements of a certain business process and enhance the expressiveness of the models 17

18 Related Work 1/2 Previous work [Korherr et al., 06] presents a UML 2 profile based on Activity Diagrams for integrating business process goals and performance measures and a mapping to BPEL [Neiger et al., 04] established links between EPCs and its additional goals with the value focused thinking framework (VFT) want to solve the problem that business process management frameworks do not meet the requirements of goal-oriented business process modeling do not focus on the measurement of goals 18

19 Related Work 2/2 [Andersson et al., 05] developed a formal definition of goal-oriented business process patterns Approach is very high level, the authors did not focus on a specific business process modelling language [Aguilar et al., 06]: developed a set of measures to evaluate the structural complexity of business process models on the conceptual level use the Business Process Modeling Notation (BPMN) focus lies on measuring the core elements of BPMN 19
