Project Requirements Calculation in Resource Analysis RRS feed

  • Question

  • I am not getting the numbers I expect to see in the Project Requirements table in my Resource Analysis.  Scenario is:

    Project 3 is a 10 day project that runs from 10/17 to 10/28, and requires both the captain and science officer roles/resources for the duration of the project.  Both roles are booked 100% for this project.  So from a resource time requirement perspective I should see in the Project Requirements table:

     

    The captain role needs 80 hours on the project and the same for the science officer - two full weeks of work each for the duration.

     

    This equates to half a man month each which is displayed as .48 (why is it not .50?)

     

    Two .48s equals .95.  (It should read 1.0).

    Thoughts?

  • Hi John,

    There are some potential rounding errors you will come across in the Portfolio Analysis around FTEs which relate to the breakdown of days to months and what you see may depend on the granularity you are using.  In this case for October there are 21 working days - so 10/21 = 0.48 (approx).  We have also tried to keep things consistent between months too - so for example if you need 1 FTE for February and you then delay the project to March, does this mean you can get by with less than 1 FTE?  Basically this is a high level planning tool - but expect to see variances if you switch the granularity about - but what you are seeing is 'correct'.

    Best regards,

    Brian.
