Adherence to Estimate KPI

Adherence to Estimate KPI

Adherence to Estimate KPI is a project management KPI that helps estimate the total duration of your projects based on Estimated Time. This KPI uses the following formula:

(Estimated Time – Actual Time) / Estimated Time

Estimated Time is total scheduled hours the project is supposed to take to be completed.

Actual Time is total actual hours the project took to be completed.

The companies should tend to reduce the value of this KPI.



This KPI helps to estimate the duration of upcoming projects if you have series of typical projects. For example if the first two phases of two projects Project 1 and Project 2 take 10% against the total duration of these projects, it is possible to calculate the estimated total duration of upcoming Project 3. Say the duration of the first phases Phase 1 and Phase 2 of Project 3 is 1.5 months (45 days in total). The total duration of Project 3 would be about 15 months (450 days): 10% * 1.5
