Summary - PDDs and modeling patterns

  • 1 PDD creation

  • From which models is a PDD created?
    A PDD is created from a meta-data model and a meta-process model.
  • De vereiste concepten bij een activiteit worden niet weergegeven, omdat er vanuit gegaan wordt dat de geproduceerde resultaten algemeen aanwezig zijn.
  • 2 Documenting PDDs

  • What has to be present for a PDD?
    For a PDD an activity table and concept table have to be present.
  • What does an activity table provide?
    An activity table provides descriptions of (sub-) activities.
  • What does a concept table provide?
    A concept table provides definitions of the concepts.
  • How many activity and concept table are used in case for one study multiple PDDs are produced?
    In case for one study multiple PDDs are produced, then all are documented in one activity table and one concept table.
  • Where are additional rules or unclarities documented?
    Additional rules or unclarities are documented in an additional statement.
  • 2.1 Activity table

  • What does an activity table include?
    An activity table includes both main activities and sub activities.
  • How are the descriptions composed?
    The descriptions are short but comprehensive.
  • 2.2 Concept table

  • What is also included in the concept table?
    - In the concept table references are included
    - cross-references can be made. 
  • What needs to be explained?
    The concept's properties needs to be explained.
  • 2.3 Including additional rules

  • What is described next to the meta-model?
    - Additional rules that cannot be depicted graphically
    - unclarities and open issues
  • 3.1 Version-dependent data

  • What is an important fact to consider in meta-data modeling about product versions?
    Products have different versions that vary over time, so the meta-data model should accommodate that in case it is essential.
  • What are examples of version-dependent data?
    - Different versions of a Release Definition, Functional Design;
    - Tracing and tracking of requirements in the release history.
  • How to keep track of the history of the data of a deliverable?
    On can keep track of the history of the data of a deliverable by using Version stamping.

    See Figure for an example.
  • 3.2 Version stamping

  • What is done with time/version related properties?
    All time/ version related properties are copied into a new Concept, called XX HISTORY and a history relationship is added in between.

    See Figure for an example.
