  1. 5th OOPSLA Workshop on Domain-Specific Modeling Meta-Modelling Support for a General Process Modelling Tool

  2. Need for a General Process Modelling Tool BPEL4WS D XPDL D Common Features D BPML D D Petri Nets … Jürgen Jung

  3. Where it Began: ECOMOD • ECOMOD – E-Commerce Modelling • Support for developping e-commerce related applications • Basing on a company‘s strategy • Supported by business process models Strategy E-Commerce Application Jürgen Jung

  4. 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 Jürgen Jung

  5. Procurement Sales Service Production Identification Overall relevance for cost reduction Supplierselection Chances for cost reduction through: Agreement outsourcing eliminating intermediaries Inbound logistics cooperation Payment automation From Strategy to Application MEMO-OrgML Selection Strategic Options Configuration Reference Process Model Generation XPDL E-Commerce Application Workflow Model Jürgen Jung

  6. 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 Jürgen Jung

  7. OrgML and XPDL – Process Types (Excerpt) Process Types in MEMO-OrgML XPDL Workflow Type manual ? • Parameters: • Participant • Resouce • Startmode • Stopmode semi-automated automated Jürgen Jung

  8. 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? Jürgen Jung
