When would resource leveling be applied to a schedule model?

Question

Options

• ABefore constraints have been identified
• BBefore it has been analyzed by the critical path method
• CAfter it has been analyzed by the critical path method
• DAfter critical activities have been removed from the critical path

• A
  14% (6)
• B
  2% (1)
• C
  76% (32)
• D
  7% (3)

Explanation

Resource leveling is applied after the critical path method (CPM) analysis because CPM first establishes the schedule's logical sequence, float, and critical path - giving you the baseline you need to understand which activities have flexibility before you start adjusting resources. Without that analysis, you'd have no way to know where you can shift work without delaying the project.

Why the distractors are wrong:

• A is wrong because you need constraints identified as inputs to build the schedule model before any analysis occurs.
• B is wrong because CPM must run first - resource leveling depends on knowing float values and the critical path to make safe adjustments.
• D is wrong and describes an invalid step; you don't remove critical activities from the critical path - that would change the project scope or logic entirely.

Memory tip: Think of it as a two-step sequence - "CPM first, then level." CPM tells you what's flexible; resource leveling uses that flexibility to smooth out resource demand. If you level before CPM, you're flying blind.
