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

  • Duty1: The bank clerk must check the credit applicant’s rating within three days after receipt of

the application form.

  • D1.1: The bank clerk must check the validity of all data provided by the credit applicant.
  • D1.2: The bank clerk must check if the credit applicant is a blacklisted customer.
  • D1.3: 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.

Modeling Support for Process- related Duties I

SLIDE 11

Modeling Support for Process- related Duties II

  • OCL (object constraint language) invariants
  • Formally define semantics of new modeling elements

INFORMATION STRUCTURES 12

OCL Constraint 3: Each Duty instance defines an attribute called associatedProcessInstance and needs to be discharged in the context of an instance of the corresponding BusinessActivity: OCL Constraint 10: The enterOperation and the leaveOperation of a Duty can only be executed if the corresponding DutyTimeConstraint is not expired:

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

slide-13
SLIDE 13

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

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
