Developping Applications on the Basis of Process Models

Programming environment Implementation is done by programmers Business logic is implemented using a programming

language Components, frameworks or class libraries may be

reused

Process-oriented systems Examples:

- Workflow Management System- BPEL4WS-Engine (Business Process Execution

Language for Web Services) Provide similar concepts like business process models

- Control flow- (Special) Resources

Process Models and Workflow Schemata

Process and workflow are similar abstractions Focus on control flow

Process models Provide the notion of

- Resources- Information Objects

Language used in our context: MEMO-OrgML- MEMO: Multiperspective Enterprise Modelling- OrgML: Organisation Modelling Language

Workflow Focusses on tasks executed by IT-resources (especially a

Workflow Management System) Standardised specification Language: XPDL

- XML Process Definition Language

Open Research Questions

Identification of common features of (business) process modelling languages

Classes of similar process modelling languages (sharing common features)

Kinds of deltas, e.g. Adding syntactic features Defining semantics, e.g.

- Operational semantics

Are current meta-modelling tools capable of providing all necessary features?
