There's a team contributing to my project, call it Team A. Team A is responsible for 200 tasks out of my yearlong, 800-task project. Each of these tasks requires one week to complete.
I don't care who (out of a team of 4 people) performs each task. So, I've created a resource "Team A", with availability 400%, and assigned each of the 200 tasks to the resource "Team A". Now when I level the project plan, MS Project automatically assigns Team A to no more than 4 of these tasks per week.
This has worked great so far, but suddenly one team member, Bob, can only work half-time. So, this team member requires 2 weeks to complete the same task. I don't see how to account for Bob without adding Bob as an individual resource and assigning Bob specific tasks by hand (which would be a pain).
Is there a way to somehow tell MS Project, for each of these 200 tasks, "I have two resources, Team A and Bob. Please assign one of Team A or Bob to this task. Team A takes 1 week to complete the task, and Bob takes 2 weeks"?
