Average Deviation of Planned Duration of Tasks

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

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 tasks.

Baseline Duration is originally estimated time spent on tasks.

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