FTE and Person days difference

[Geeky]

Whats the difference between FTE and Person days while creating resource plan?

[Jeff Currier]

I believe the difference is just the units of how you want to enter the data.  If you do 1 FTE for a week, then that is 5 person days.  But if you wanted to do something like 0.5 FTE for a week, then that would be 2.5 person days.  For a long project, putting in someone as 0.3 FTE for three months may be easier than calculating how many person days that would be.

In the end, you would use the way you generally refer to people in resource loading.

1 FTE = 1 week (5 days). Is it a standard definition or do we configure it somewhere in the system?

I have submitted a plan with FTE as 1. I see hours auto calculated as 80 and cost as 4000$. How is it getting calculated?

You can request a resource plan using one of the following options:

• Hourly: The request is in terms of the number of hours the resources are necessary.
• FTE: The request is in terms of an equivalent value that represents full-time work. When the request type is FTE, planned hours are calculated as: Average Daily FTE * number of working days in resource plan * the FTE value. The average daily FTE hours are specified in User and Group records. If there is no value specified at User or Group record, the average daily FTE hours is taken from the Default Average Daily FTE property.

  The number of working days is calculated based on the users schedule for a user resource or the default schedule for group resources. The default schedule is taken from Default Schedule Name property.

  For example, the average daily FTE hours is 40 hrs for a group, the resource plan dates are from Sep. 01 2015 to Sep. 10, 2015. and you specify the FTE as 0.5.

  Then planned hours = 40 * 8 * .5 = 160 hours. This assumes that there are 8 working days between Sep. 1 and Sep. 10.

  Note: Capacity is not derived from FTE, but from schedules. Both FTE and schedules must be in synchronization with each other.
• Person days: The request is in terms of person days. When the request type is person days, planned hours are calculated as: Total number of person days * Average Daily FTE Hours/Hours Per Person Day. For example, the Average Daily FTE Hours/Hours Per Person Day is 8 hrs for a group, and you specify the person days as 3. Then planned hours = 8 * 3 = 24 hours.

Thanks, for explaining with example. If I update the planned dates of a project, does it update the start and end dates of the resource plan? Ideally it should, right but system is not updating the dates for resource plan. Can you confirm this once?
