How to show Resource overallocation within one day in MS PROJECT 2016?



I have a question from one of my Blog Readers:

I have the following issue … I have a resource with an 8-hour working day. I assign him a task starting 9:00 am with a duration of 3 hours. I also assign him a task starting 10:00 am with duration 1 hour. Project does not flag it as an overallocation, I guess it’s because it does not go beyond the 8 hour restriction for a working day. But there is a conflict with the tasks since both have to be performed by the same resource at the same time. Is there a way to have Project indicate this conflict?
Thank you”

Well, here we are talking about showing overallocation within one day. I’ll show you that with MS PROJECT 2016!

First I will create a simple Project with two Tasks:

  • First Task with Duration 3 hours – starting at 09:00
  • Second Task with Duration 1 hour – starting at 10:00


Now I‘m going to create John, as Resource with 100% availability for this Project:


Now, let’s say that John will work on both Tasks:


John is available supposed to work 8 hours per day, and since he will work 3 hours for First Task, and 1 hour for Second Task, he is not overallocated. Or is he? He is not overallocated in one day (he will not work more than eight hours per day), but what about during the day?

I will change Timescale on the Gantt Chart:





and I will get:


As you can see, John IS overallocated between 10:00 and 11:00 but, it is not show on the screen. How to get that. Follow this step:


and you will get:


John is now marked as overallocated.

If Leveling option is set Day by Day then John will be marked as overallocated only if he is supposed to work more than 8 hours (in my example) per day, no matter if he is supposed to work on two or more Tasks at the same time during the day. But if this is set to Hour by Hour it means that John will be overallocated when he has to work during the day at the same time to two ore more Tasks.

Hope this helps.
