Guideline: Standard Categories in the UMF
This guideline provides some recommendations on how to define and use standard categories in the Unified Method Framewok (UMF).
Relationships
Main Description

The Unified Method Framework (UMF) defines some constraints with regards to the definition and use of standard categories. Those constraints vary for the different standard category types.

The UMF implements a Delayed Assignment approach for disciplines, domains and work product kinds. It does not implement a delayed category assignment for role sets because the definition of roles and role sets are strongly linked. Roles are assigned to role sets in the same plug-in as where the roles are defined, the Role Definition plug-in (their definitions are shared). For more information on roles in the UMF, see Guideline: Roles in the UMF. The UMF also does not implement a delayed category assignment for tools because the assignment of tool mentors to tools does not change (tool mentors are written for a specific tool). For more information on tools in the UMF, see Guideline: Tool Information in the UMF.

The "delayed standard categories" (disciplines, domains and work product kinds) are defined in a Category Definition Base plug-in. Elements are assigned to these categories in the Assign plug-ins associated with the Base plug-in that contains the elements to be assigned (tasks and work products). For information on how these assignments are defined, see Guideline: Delayed Assignment in the UMF

The benefits to the UMF approach to standard categories are:

  • The same categories can be used with different element assignments (shared Category Definition plug-ins)
  • Alternate category definitions and element assignments can be defined (provide alternate Category Definition and Assign plug-ins)

For more information on Category Definition plug-ins, Role Definition plug-ins and Tool Definition plug-ins, see Concept: Practice Library Plug-In Types. For more information on Base and Assign plug-ins, see Concept: Practice Library Plug-In Parts

For an example of a Category Definition Base plug-in, see UMF Category Definition Base Plug-In Example.
