PMP Formula: Variance of Activity

PMP Formula Variance of Activity

Variance of Activity is an indicator to activity risk level, which prompts the course of action to take. Activity variance calculation involves taking the square of activity standard deviation. Equation: Variance of Activity = ((P - O) ÷ 6) ^ 2

Formula Definition
Variance of Activity
  • = ((P - O) ÷ 6) ^ 2

  • = (Standard Deviation of the Activity) ^ 2

  • O = Optimistic Estimate

  • P = Pessimistic Estimate
