I'm just getting started with Microsoft Project and I'm using it to plan out a project we have. There are several tasks on it where I would like the whole team (5 people) to work on a Task. My understanding is that if I put 5 Resources, each at 100% Units, on a Task it would make the Work be 5 times as much as the Duration. This was the case when I initially entered these Tasks, but when I came back to them later (after working on other tasks) I noticed that the Work is now the same as the Duration.
(Bonus, the one at the bottom seems to have a completely arbitrary relationship between Duration and Work)
If I manually change the Work value to what it should be and then choose "Increase the hours resources work per day (units) but keep the same duration." then it sets 4 of my resources to 0% and the remaining resource to 500%. Changing all resources back to 100% makes the Work equal to the Duration again.
I think this issue started after I clicked "Level All" in the Resources menu, but I didn't notice the exact moment so I can't be completely sure.
