Effort

The total amount of labor needed to finish a scheduled activity or a WBS component, typically measured in person-hours, person-days, or person-weeks; it is not the same as duration, which is the elapsed calendar time.

Key Points

  • Effort measures labor quantity, not calendar time.
  • Common units are person-hours, person-days, or person-weeks.
  • Duration is influenced by resource allocation; Duration ≈ Effort divided by effective resource hours available.
  • Adding people may shorten duration, but total effort often stays the same (assuming similar productivity).

Example

An activity requires 80 person-hours. With one full-time resource at 8 hours per day, the duration is about 10 days. With two full-time resources, duration is about 5 days (if efficiency holds). The effort remains 80 hours in both cases.

PMP Example Question

Which term refers to the total labor required to complete a work package, typically expressed in person-hours, and should not be confused with elapsed calendar time?

  1. Effort
  2. Duration
  3. Work package
  4. Resource leveling

Correct Answer: A — Effort - the amount of labor required

Explanation: Effort quantifies labor input (person-hours/days/weeks), whereas duration is the elapsed time from start to finish.
