When to use it

A useful fit

Use it when the required finish is at risk and there are credible alternatives for the work controlling that finish.

Know the limits

Do not add people indiscriminately or overlap work whose inputs are too unstable. Check bottlenecks and rework risk first.

How to use it

  1. Identify the activities currently controlling the finish.
  2. Compare added-capacity and overlap options, including cost and introduced risks.
  3. Recalculate the full schedule and agree owners, safeguards and a review trigger.

Worked example

A team considers starting training preparation before acceptance testing ends. It limits early work to stable workflows and holds uncertain screenshots until the tests pass, comparing the expected time gained with revision effort.

Common pitfalls

Speeding up a non-critical activity may not change the project finish.
