I have created a fixed-work task of 4 weeks.
The task start is August 1st.
I have three resources, each available at 100%: Peter, Paul, and Curley.
For the whole month of August, Peter and Paul will be slaving away at their desks. Curley will be drinking cocktails on the beach.
For Task-resource assignment:
If I apply only Peter OR Paul (at 100% units), then the task completes 4 weeks later at End of Month August. (as expected)
If I apply both Peter AND Paul (100%) then the task completes mid-August (as expected).
If I apply Curley only (100%), then his work starts after his vacation is over (i.e. starts Sept 1) and concludes 4 weeks later at EOM September (also as expected).
Now, if I apply Peter AND Curley to the job (100%), the project finishes mid-September (using 2 of Peter's weeks during the month of August and then waiting until Curley comes back from vacation to do the 2 weeks that he owes).
How can I get Project to calculate duration based on the assumption that Peter is working, even while Curley is on vacation?
The result (Peter & Curley assigned) would be a task that finishes at the same time as would be calculated if only Peter were resourced.
