When resources perform work on an activity, you can choose how the resource units or costs are spread through time. This is done using a resource curve. To see this column, right-click on the Resources tab on an activity, customize the columns, and choose Curve.
A wealth of curves from which to choose is presented. These curves will determine how the effort and cost of a resource is spread over time. This could reflect expected cost for labor or the expected consumption of a material resource.
To view and modify resource curves, choose the menu Enterprise | Resource Curves. A list of resource curves, much like the one shown in the previous screenshot, appears. This screen allows you to add, modify, and delete curves. In the EPPM web client, resource curves are defined in the Resource Curves section under the Administer | Enterprise Data. Because so many standard curves come standard with P6, there may be no need to define your own.
