Resource overallocation

N

Sometimes a resource appears overallocated even if the hours assigned to him
are less than the hours specified in calendar. For example: a resource X
works 8 hours per day. On monday he has 1h allocated for project1 and 4 hours
for project2. The resource usage view shows 5h in red, why?

In Microsoft Project, a resource overallocation occures when the resource is
assigned more work in any time period than the resource is capable of
performing. For example, assigning the resource to perform 240 hours in a
single week is certainly an overallocation. In your situation, I believe
your resource is assigned to perform 2 hours of work in a single 1-hour time
period. To know this for sure, apply the Resource Usage view and then zoom
the timescale to Hours over Quarter Hours. Examine the resource in
question. I believe you will see 30 minutes of work during each 15-minute
time period of that one hour to which I refer. Hope this helps.

You assigned a resource to two tasks that run concurrently during that one
hour time period. This particular overallocation is small, and I would
encourage you to simply live with it, knowing that the resource can
successfully complete both tasks on Monday. In fact, when the resource
submits actuals for the two tasks, the overallocation will disappear.

On the other hand, to avoid major overallocations that can cause your
project to slip, you should always make sure a resource is actually
available to perform a task before actually assigining the resource to that
task. Project Server provides you with several means for doing so,
including:

1. The Resource Usage view shows resource allocation across all projects in
the portfolio
2. The Assign Resources dialog has an Available to work filter
3. The Resource Center page has an availability option

Hope this helps.

If you click tools > level resources and select leveling hour by hour
basis, this will resolve overallocation. Low id task will start first.
