Variance

A measurable difference between actual results and the approved baseline or expected value.

Key Points

  • Always calculated against a defined baseline (scope, schedule, cost, quality, or other metrics).
  • Can be favorable or unfavorable; the sign convention (positive/negative) should be defined in the management plan.
  • May be shown in units (days, dollars, defects) or as a percentage, and tracked over time to spot trends.
  • Used in variance analysis and EVM to trigger root-cause investigation, corrective actions, or change requests based on thresholds.

Example

The cost baseline for a phase is USD 200,000, but the team spent USD 215,000. The cost variance (Actual - Baseline) is +USD 15,000, indicating an overrun that requires analysis and potential corrective action.

  1. Variance

  3. Risk
