Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
100% rule
The 100% rule in WBS creation requires that the WBS captures all deliverables and work defined in the project scope, and nothing outside that scope. Decomposition is the process of breaking down work, but the 100% rule specifically ensures completeness.

Why it's wrong here

100% rule
Why this is correct
