Introduction  Demand for integrated modeling support of business processes and process-related duties  Standard (process) modeling languages do not provide native language elements for process- related duties  UML metamodel extension to model processes, process-related duties, and responsibilities

A Motivating Example Duty 1 : The bank clerk must check the credit applicant’s rating within three days after receipt of  the application form. D 1.1 : The bank clerk must check the validity of all data provided by the credit applicant.  D 1.2 : The bank clerk must check if the credit applicant is a blacklisted customer.  D 1.3 : The bank clerk must check the credit applicant’s current debt obligations.  Compensation D1 : If D1 is not discharged within three days after receipt of the application form,  forward this duty to another bank clerk. Review D1 : If an applicant has been rejected twice, a second bank clerk must confirm the credit  applicant checks.

Duty States and State Transitions Duties have certain states

Meta model Essential relations of modeling elements

Modeling Support for Process- related Duties I

Modeling Support for Process- related Duties II  OCL (object constraint language) invariants  Formally define semantics of new modeling elements OCL Constraint 3: Each Duty instance defines OCL Constraint 10: The enterOperation and an attribute called associatedProcessInstance the leaveOperation of a Duty can only be and needs to be discharged in the context of an executed if the corresponding instance of the corresponding BusinessActivity: DutyTimeConstraint is not expired: INFORMATION STRUCTURES 12

Modeling Duties from Different Perspectives I  Lightweight graphical notation to visualize new modeling elements  Presentation option to visualize relations that are formally defined through the metamodel extension and OCL invariants

Modeling Duties from Different Perspectives II  Refined modeling of duties via UML Interaction diagrams  Definition of detailed invocation sequence of messages  Mapping of process definitions and related duties to the corresponding software system

An Example Process with Duties I Process Perspective Extended credit application process including new modeling elements

An Example Process with Duties II Responsibility and Duty Perspective Modeling Responsibiliy for Tasks and Duties and Relations of Duties

An Example Process with Duties III Sequence Perspective

Conclusion  Integrated modeling of business processes and process-related duties  Native UML extension  Standard process modeling languages do not provide corresponding language elements  UML meta-model extension  Duties modeled in extended Activity diagrams  Classes define behavior for each duty  Refined modeling via UML Interaction diagrams  OCL constraints define semantics  Integration with other UML-based approaches and/or tools
