ITPEC IP October 2018 Question 56
ITPEC IP October 2018 — Question 56 of 100
WBS decomposition should continue until work is at a manageable level where time and cost can be estimated. Work packages need enough detail to support assignment, scheduling, budgeting, monitoring, and control without creating unnecessary administrative complexity.
Answer (a)
Why not others:
- the customer retains responsibility for defining and controlling outsourced scope
- project-management work such as progress meetings also consumes resources and belongs in the WBS
- experience from similar projects helps decomposition but does not eliminate the need to tailor it
Key rule: Decompose all project scope into work packages that can be reliably estimated, owned, and controlled.
