Which of the following inputs is required for the WBS creation?

Question

Options

• AProject Quality Plan
• BProject Schedule Network
• CProject Management Software
• DProject Scope Management Plan

• A
  4% (1)
• B
  11% (3)
• C
  4% (1)
• D
  82% (23)

Explanation

Option D is correct because the Project Scope Management Plan is a key input to the Create WBS process (PMBOK 5.4). It defines how the scope will be decomposed and structured, giving the team the governance rules and approach needed before building the WBS.

Why the distractors are wrong:

• A (Quality Plan): Quality planning is a separate process; it doesn't guide how deliverables are decomposed into work packages.
• B (Schedule Network): This is an output of Sequence Activities, which happens after the WBS is created - you can't sequence work you haven't yet defined.
• C (Project Management Software): Software is a tool/technique, never an input - inputs are documents or artifacts, not tools.

Memory tip: Think "Plan before you Break." The Scope Management Plan tells you how to break things down, so it must come first. Also, anything labeled "network" or "schedule" belongs to time/schedule processes that depend on the WBS - they come after, not before.
