Equivalent persons (EQP) is calculated based on the calendar selected when a project is first defined in the Project Maintenance window.
Calendar |
Calculation based on: |
Resource Work |
Hours, converted from the Hours/Day and Days/Week field identified in the Resources window.
|
Equivalent Person Months |
Equivalent Person Month hours entered in the fiscal calendar |
MPM uses the following formulas when calculating equivalent persons.
Calculation |
Equation |
Standard Hours |
Hours x (Efficiency / 100) / (1 + Scrap & Rework / 100) |
Hours |
Standard hours x (1 + Scrap & Rework / 100) / (Efficiency / 100) |
Person Months for reporting purposes only |
Person hours / equivalent person month hours entered in the fiscal calendar |
Person Months for estimating purposes only |
Hours / hours per day / days per week / (52 / 12) |
Equivalent Persons if Resource Work Calendar was selected in Project Maintenance. |
Hours in estimate / (resource hours per day x number of work days in estimate) |
Equivalent Persons if Equivalent Person Month Hours Calendar was selected in Project Maintenance. |
Hours in estimate / ((calendar days in estimate / calendar days in month) x equivalent person month hours entered in the fiscal calendar) |
For reporting, the Person Months are always calculated using the number of calendar hours entered in the Equivalent Person Month Hours field of the Fiscal calendar. If all months in the calendar are zero, Person Months are not shown on the reports.
For reporting, the Equivalent Persons calculation always reflects the projects calendar designation (Resource Work or EQPM Hours) which was saved at the time resources were estimated. It is not recalculated at report run time. If the designation of Resource Work or EQPM Hours was changed in the Project Maintenance window after estimating, the change is not reflected on the report unless the estimate itself is changed or the project is repriced.
