Determine whether one of the General Subset Definitions suits your need. If this is the first subset being created for the current phase of development, consider the following subsetting task definitions are typical for:
Analysis
Design (first subset)
Procedure step maintenance
Workstation construction
If these subsets lack the detail that your task requires, see the procedure that follows in General Subset Definitions section.
Use the subset definition appropriate for your development phase as a guide, and create a subset. See the steps that are outlined in the Add Subset Definition section.
