Best Uses  Add the Assignment Delay task field to the Task Usage view when you want to display delay information for assignments under a task.

Best Uses  Add the Assignment Delay resource field to the Resource Usage view when you want to display delay information for assignments under a resource.

Example  You are reviewing delay information for assignments. You add the Assignment Delay field to the Resource Usage view. No information appears in the Assignment Delay field next to the resource names. However, the delay for their assignments appears in the assignment rows below each resource name.

Entry Type  Calculated or entered (calculated or entered field: A field in which the value is determined by Project based on information in other fields. Information that you enter in the field yourself overrides calculated values.)

How Calculated  Microsoft Office Project calculates any difference between the assignment start date and the task start date. This difference is the assignment delay.

Assignment Delay = Start (task) - Start (assignment)

If you enter an assignment start date that is later than the task start date, the assignment delay field will change to reflect the difference between the assignment start date and the task start date.

Best Uses  To have an assignment start sometime after the start of the task, enter a value in the Assignment Delay field. Add the Assignment Delay field to the Task Usage or Resource Usage view when you want to review, filter, or edit the assignment delay.

Example  The "Conduct client meetings" task is assigned to Sean, Chris, and Jamie, with a duration of 5 days. However, Jamie is not to be involved with the task until the final day. To schedule Jamie for the final day of the task, type 4d in the Assignment Delay field (and 1d in the Work field) for Jamie's assignment.
