How to prevent Resource Overallocations by using the Team Planner–WATCH OUT!



In MS PROJECT 2010 there is a feature which can automatically prevent Resource Overallocations.

I will add two tasks and two resources to the project:




Now I will assign them to both, Task 1 and Task 2:


and I will get:


Now I will open the Team Planner:


and then:


and I will get:


You can see that both resources are overallocated!

Now I will arrange the Team Planner to prevent this situation:


and I will get:


As you can see, MS PROJECT 2010 has move Task 1 to start after Task 2, and Resources are not Overallocated any more!

But! I will go back to the Gant Chart  and I will add two new Tasks and I will assign Resource 1 and Resource 2 to them:


As you can see, both Resources are Overallocated again. But I will now go back to the Team Planner and I will do NOTHING, but I will get:


As you can see, all Task are Rescheduled automatically because the Prevent Overallocations button has remained in “turn on” mode:


So, DO NOT TURN THIS BUTTON! If you do, and you are 100% sure that you want from MS PROJECT 2010 to do the “leveling”, do not forget to turn this feature off before you are leaving Team Planner. Leveling is hard to “undone”, so use it if you really need it!

    i know this is an old forum, but I found this very useful.

    the main issue we have where I work is that no one cares about seeing the error message, and they don’t want to reschedule.

    thanks for the information however.

    Thanks for your blog which I’ve found very useful.
    The Team planner view is only available in MS Project 2010 *Professional* not in Standard.
