Resource Overallocation

Online Help > Resource Overallocation

What are overallocated resources?

​A resource is overallocated when it is assigned too much work to complete within the resource's available time. You can resolve resource overallocation by adjusting either tasks or resources in your project.

What is Overallocated field?

The Overallocated field indicates whether a resource is assigned to more work on a specific task or all tasks that can be completed within a normal working capacity.

What is Unit availability?

Unit availability represents an amount of time, expressed as a percentage or a decimal number, that a resource can be scheduled for assigned work. It refers to the availability of a resource; for example, a resource may be available 50%, 100%, or 300% of full time.

What is Unit Availability field?

The Unit Availability field contains the percentage or number of maximum units that a work resource is available to accomplish on any tasks during any selected time period, as distributed over time.

What causes resource overallocation?

A resource overallocation can be caused by increased duration of tasks, decreased unit availability for resources, and resources assigned to work full-time on more than one task at the same time.

1. A resource assigned to work full-time on more than one task at the same time - For example, if you assign a resource to two tasks of eight hours each on the same day, then the resource is overallocated because only one eight-hour task can be accomplished on that day. To view a resource's workload, on the View menu, click Resource Usage. Look at the number of tasks assigned during times of overallocation.

2. Increased duration of tasks - If you increase a task's duration, then the amount of work assigned to the resource also increases and may cause the resource to have too much work at one time. To view a resource's workload, on the View menu, click Resource Usage. Look at the number of hours of work assigned each day.

3. Decreased unit availability for resources - For example, a resource's availability is reduced from 100% units to 50% units because it is working part-time. Or, more specific nonworking time is entered on the resource calendar, such as Monday through Friday, 1:00 P.M. to 5:00 P.M. To find out if the resource has decreased unit availability, on the View menu, click Resource Sheet.

Can Project Plan 365 solve automatically the resource overallocation?

Project Plan 365 app will not move your task automatically if you have an overallocated resource on two parallel tasks.
The application tells you that you have an overallocated resource by making the entire resource font with red in Resource Sheet view.
In order to solve the overallocation, you need to link the tasks and specify a predecessor.

My project plan does not take limited ressource into account, means 2 tasks remain in parallel with only 1 ressource allocated 100%. How can I plan my project automatically with limited ressources?

Project Plan 365 app will not move your task automatically if you have the same resource on two parallel tasks.

The application tells you that you have an overallocated resource by making the entire resource font with red in Resource Sheet view.

If you want tasks to be in sequence, you need to link the tasks and specify a predecessor.

How to change the working time for a Resource?

To change the working time of a resource, you need to look in the resource calendar. To do this, go to the Project menu and select Change Working Time. For the desired resource, look for decreased working time on the resource's calendar.
