154. Fixed Duration and effort driven Task - Microsoft Project Online

The question: “Just a question. When I assigned a task to Fixed Duration, WITH EFFORT DRIVEN I see that Project has calculated some of the resources to work 50% or 33%. How does that work then? I had a 5 days work, with 4 resources. So after calculating, they still work for 5 days, still with four resources but of course less work. Thing is, I get two of these resources working 100% and one with 50% and the other with 33%! I cannot, for the life of me, work out WHY WOULD PROJECT calculate that when ALL RESOURCES are 100%.” Teh answer is in this vlog!
