• What are examples of a meta-process model?

  Examples of a meta-process model are:
  

  • development project plan;
  • design process;
  • process improvement process;
  • daily build process.

• How are meta-process models modeled in the PDD notation?

  In the PDD notation, meta-process models are modeled with a similar notation as the UML activity diagrams.

• What are the usages of (meta-) process modeling?

  The usages of (meta-) process modeling are:
  

  • documenting the process;
  • communicating the process;
  • comparing processes;
  • re-using the process;
  • development of tool support.

• What is the definition of a process?

  A process is a set of partially ordered process steps intended to produce a desired product.

• What is done with process models?

• 1.1.1 Process concepts

• What are process concepts?

  Some process concepts are:
  

  • activity;
  • decision;
  • condition;
  • flow;
  • trigger;
  • state;
  • sub-process;
  • etc.

• 1.1.2 Difficulty of processes

• What are difficulties of processes?

  • Many terms for process perspective: process, action, activity, step, procedure, practice, task, phase, stage, plan, etc.;
  • no formal abstraction levels of the process perspective;
  • process size is difficult to measure;
  • processes of different granularity (de mate van detaillering) levels are easily mixed;
  • it's the result that counts, i.e. (d.w.z.) the process is subordinated (ondergeschikt) to the deliverable.

• What are the distinctions between a model and meta-model?

  The distinctions are:
  

  • M2 is method layer (Meta-model);
  • M1 is development layer (Model);
  • M0 is reality layer (Instance).
    

• 2 PDD notation

• What are notations of the activity/process side of a PDD?

  - Activities;
  

  • sequential;
  • unordered;
