Lesson 7.5. Using Material Resource Consumption Rates

In case you've forgotten, material resources are the goods needed by work resources to complete tasks. This project has one material resource: blank CDs. When you create a material resource, you enter its name, material label, and Std. Rate. But when you assign a resource to a task, you should be aware of the consumption rate you want to use. There are two different consumption rates:
Fixed consumption rate: An absolute quantity of the resource will be used, no matter how long the task takes. For example, if you need to copy 5,000 CDs, that amount is fixed, no matter how long it takes to complete the task.
Variable consumption rate: The quantity of the resource varies, depending on the duration of the task. For example, when recording narration, more recording tape is used as more narration is recorded. By using a variable consumption rate, the calculation for the material resource will be more accurate.
In this lesson, we'll create a material resource assignment using a variable consumption rate.
Select View The tasks in the project appear.
Select the Record narration task.
When Jules, the resource assigned to this task, records narration, she saves the narration onto DAT recording tape.
Let's create an assignment that reflects using this material resource.
Click the Assign Resources button on the Standard toolbar.
The Assign Resources dialog box appears.
Scroll down to the Recording tape resource.
This material resource will be consumed at a variable consumption rate. Each tape is 60 minutes long, so one tape will be used per hour.
Enter this rate in the resource's Units field.
Click the Units field. Type 1/h and click the Assign button.
The resource is assigned to the task at a consumption rate of one DAT tape per hour, as shown in Figure 7-5.
Let's see how Project calculates this cost for the task.
Select View Project displays the tasks and the resources assigned to them.
Select the Recording tape resource. Click the Assignment Information button on the Standard toolbar.
The Assignment Information dialog box appears, as shown Figure 7-6s.
TO APPLY A VARIABLE CONSUMPTION RATE TO A MATERIAL RESOURCE ASSIGNMENT:
SELECT THE TASK TO WHICH YOU WANT TO ASSIGN THE RESOURCE.
CLICK THE ASSIGN RESOURCES BUTTON ON THE STANDARD TOOLBAR.
ENTER THE VARIABLE CONSUMPTION RATE IN THE UNITS FIELD OF THE MATERIAL RESOURCE.
SELECT THE MATERIAL RESOURCE AND CLICK THE ASSIGN BUTTON.
TO VIEW MATERIAL RESOURCE COSTS:
SELECT THE MATERIAL RESOURCE.
CLICK THE ASSIGNMENT INFORMATION BUTTON ON THE STANDARD TOOLBAR.
