Instead of Project separating work evenly throughout the task duration, I want the work to be separated along a curve. For example, the purchasing group works more during the beginning of the project and less towards the end. How do I show this?

Select the Task you want to change resource profile for and then change your view to Task Usage. Now double-click the resource you want to apply a curve to and this will open the Assignment Information dialog.

Under the General tab, change the Work contour from Flat to Front Loaded
