Effort Deviation: Effort deviation is the percentage of additional effort spent during the execution of projects, over what was planned/approved for in the beginning. It is an indicator of the estimation capability, as well as implementation skills of the project team (or project manager).
The deviation in planned vs. actual effort arises when either the estimation has not been done accurately or the scope is ambiguous and hence it lead to effort and thereby cost overrun.
Effort Deviation is calculated using this formula: Effort Deviation = (Actual Effort - Baseline Effort) * 100/(Baseline Effort)
Actual Effort = Actual timesheet effort logged by the resources against task assigned to the user for the project.
Baseline Effort = Planned effort for ‘Tasks’ at the start of the module.
