Average Deviation of Planned Duration of Projects

Average Deviation of Planned Duration of Projects

Average deviation of planned duration of projects is a key performance indicator that shows average duration variance of projects in days expressed as the difference between the planned duration and the baseline duration of projects.

Deviation of planned duration (Duration Variance) can be calculated by the following formula:

Deviation of Planned Duration (Duration Variance) = Duration - Baseline Duration

Duration is the actual scheduled time spent on projects.

Baseline Duration is originally estimated time spent on projects.

This KPI helps to compare the variation of time spent on projects over some time span.
