Question details

The user needs to schedule a task across a two-week period for a resource working part-time (2.5 days per week) on the project.

Product: Microsoft Project
Device & OS: not provided
Scenario: Assigning a part-time resource to a task spanning two workweeks to ensure accurate workload distribution.
Observed behavior: The task needs to reflect a 50% availability (2.5 days per week) workload over a continuous two-week duration without overallocating the resource.

Before you start

Confirm the exact working hours and availability of the resource before modifying task types or adjusting the project calendars.

Solution 1Recommended

Use Fixed Work Task Type and 50% Resource Allocation

Configure the task to Fixed Work and assign the resource at 50% availability to automatically spread the work over a two-week duration.

When dealing with part-time assignments across multiple projects, setting the task type to Fixed Work ensures that the total effort remains constant. Adjusting the resource availability to 50% will naturally extend the duration to two weeks.

Set Task Type to Fixed Work

Double-click the task to open the Task Information dialog box, go to the Advanced tab, and change the Task Type to 'Fixed Work'.

Define the Work Amount

In the Task Information dialog or the Work column, enter 5 days (or the equivalent hours) for the total work required.

Assign the Resource

Assign the specific resource to the task and set their Assignment Units (or Max Units) to 50% to reflect their 2.5 days per week availability.

Adjust Calendar for Specific Finish Times

If the task requires an exact cutoff time (e.g., Wednesday at noon), modify the resource's calendar in the 'Change Working Time' menu to reflect these specific hours.

Frequently Asked Questions

What does 'Fixed Work' mean in Microsoft Project?

Fixed Work is a task type where the total amount of work (in hours or days) remains constant, regardless of any changes made to the task's duration or resource assignment units.

How do I change a resource's working calendar?

Navigate to the Project tab, click 'Change Working Time', select the specific resource from the 'For calendar' drop-down menu, and adjust their specific working days and exception times.

Can I set a task to finish at a specific time of day?

Yes, you can achieve this by creating a custom resource calendar that ends working hours at your desired time (like Wednesday at noon), or by manually entering the time in the Finish date column.

Why did my task duration change when I assigned a part-time resource?

When a task is set to Fixed Work and you assign a resource at less than 100% capacity (such as 50%), Microsoft Project automatically recalculates and extends the duration to spread the fixed amount of work over the available time.
