7 Workflow Management

Nota:

• part of research area CSCW which deals mainly with the support of organization wide work-sharing processes based on formally established activities, communication relationships and decision making competencies

1. Global Process Model for layout of information supported organization structures (Lifecycle of continuous change)

   Nota:

   • Organizational Development Development of Information Systems Formation of Corporation
2. Basics of Workflow Management

   Nota:

   • Workflow Managment Systems don't really have a theoretical foundation, they are more practically oriented
   1. Activities
      1. Support of returning, formal, predictable events
      2. Decomposition of operations in activities
   2. Productive
   3. Collaboration
   4. Administrative
   5. Ad hoc
   6. Phases of WFM
      1. Modeling
      2. Evaluation
      3. Execution
   7. Tasks
      1. Execution and control of WF
      2. modeling of WF
      3. Simulation of WF
3. Elements of WFMS

   Nota:

   • Controller, program manager, role resolution, notification, synchronization, data manager, history manager, causality manager
   1. Generic implementation model
   2. Types of Workflow Tools
      1. Form Processors
      2. Line-of-Business App
      3. Mainframe and Legacy App
4. Modeling of Workflows
   1. Levels of Modeling

      Nota:

      • Modeling of Activities Modeling of actors Modeling of dependencies Modeling of causalities
   2. Process modeling
   3. structural modeling
   4. Jablonski - Terms

      Nota:

      • abstract level: rules are defined concrete level: models how to do
   5. 4 layer model

      Nota:

      • process modeling requires several modeling levels
   6. Normative language approach

      Nota:

      • developer and user speak different languages. Gap should be closed trough a language which is defined by vocabulary and grammar
      1. Sequence
      2. Conditional Branching
      3. Unconditional Branching
   7. Workflow Management Coalition

      Nota:

      • set up general model how to define business processes to be able to execute them as workflows
      1. Meta process model
   8. Semi-formal language

      Nota:

      • can't be automatically converted to computer language
   9. Formal language
      1. Petri Nets
