2. If the work on the impacted component is started but not completed, the CR
would be handed over to the team member (or members) carrying out the work
for implementation. The CR would then be incorporated into the deliverables.
3. If the work on the component impacted by the CR is completed, then the CR
would be kept pending to be implemented either at the end of the project or at a
convenient time, such as when some resources become free or a part of the
team is idle waiting for some approval or clarification and so on.
If the project was following a strategy of holding CRs and then retrofitting them
at a convenient point in time, the following steps would followed to implement the
CRs:
1. Each CR is further analyzed to determine the components and deliverables
impacted by it.
2. At the completion of analysis, CR implementation activities are consolidated
into packages normally by the component.
3. Work allocation would be made so that all CRs pertaining to one component or
one set of related components would be allocated to the same set of team
members.
