How to allocate resources in detail (OmniPlan 3.14.2 for Mac)


I am trying to accomplish something that - I think - should be quite common, but I cannot figure it out.

I have a task that requires a 9 weeks effort, and multiple resources that can work on it. I would like to assign resources to this task in a detailed way, at least week by week. As an example, assume I have five available resources, R1 to R5, and that the task is to start on W1. I would like to do something like:

T:   1  2  3 
R1:  X  X  X 
R2:  -  -  X
R3:  -  X  - 
R4:  X  X  - 
R5:  -  X  X 

This means that R1 will work on the task on W1, 2 and 3; R2 will work on it on W3, and so on. As you can see, the total number of weeks is 9, and the duration is 3 weeks.

I could do this with the percentages, but I find it a bit counter intuitive, and this does not allow me to know what R2 is doing on W2 or W3; I only know it’s allocated 33.3% on that task, but not actually when the work is going to happen.

Is there any way to achieve what I need?

Thanks for your help!
