MicrosoftВ® Office Project 2007 Step by Step (Step By Step (Microsoft))

In the Resource Usage and Task Usage views, you can see exactly how long each resource is scheduled to work on each task. In addition to viewing assignment details, you can change the amount of time a resource works on a task in any given time period. There are two ways to do this:

• Apply a predefined work contour to an assignment. Predefined contours generally describe how work is distributed over time in terms of graphical patterns. For example, the Bell predefined contour distributes less work to the beginning and end of the assignment, and distributes more work toward the middle. If you were to graph the work over time, the graph’s shape would resemble a bell.

• Edit the assignment details directly. For example, in the Resource Usage or Task Usage view, you can change the assignment values directly in the timescaled grid.

How you contour or edit an assignment depends on what you need to accomplish. Predefined contours work best for assignments in which you can predict a likely pattern of effort-a task that requires considerable ramp-up time might benefit from a backloaded contour, for example, to reflect the likelihood that the resource will be most productive toward the end of the assignment.

In this exercise, you apply a predefined contour to one task’s assignments, and you manually edit another assignment.

1. On the Edit menu, click Go To, enter 79 in the ID box, and then click OK.

Project scrolls to task 79, Record final narration. This task has three resources assigned to it.

As you can see in the timescaled data at the right, all three resources are scheduled to work on this task at a regular rate of eight hours per day (that is, 100 percent of their available working time)-except for the first and last days of the task. These assignments have a flat contour. This is the default work contour type that Project uses when scheduling work.

You want to change Michael Patten’s assignment on this task so that, although the other assigned resources work full-time, he starts with a brief daily assignment and increases his work time as the task progresses. He should continue working on the task after the other resources have finished their assignments. To accomplish this, you will apply a back-loaded contour to the assignment.

2. In the Task Name column, select Michael Patten, the second resource assigned to task 79.

3. On the Standard toolbar, click the Assignment Information button.

Project displays the Assignment Information dialog box.

4. Click the General tab if it is not already selected.

5. In the Work Contour box, select Back Loaded, and then click OK to close the Assignment Information dialog box.

Project applies the contour to this resource’s assignment and reschedules his work on the task.

If you scroll the timescaled data to the right, you see that in each successive day of the task’s duration, Michael Patten is assigned slightly more time to work on the assignment. Because Michael Patten’s assignment to this task finishes later than the assignments of the other resources, Michael Patten determines the finish date of the task. One common way to phrase this is that Michael Patten is the driving resource of this task; his assignment determines, or drives, the finish date of the task.

You also see a contour indicator in the Indicators column displaying the type of contour that is applied to the assignment.

6. Point to the contour indicator.

Project displays a ScreenTip describing the type of contour applied to this assignment.

Next, you will directly edit another task’s assignment values.

7. On the Edit menu, click Go To, enter 2 in the ID box, and then click OK.

Project scrolls vertically to task 2, Review script.

Note that Clair Hector is currently assigned four hours per day for each day of the assignment’s duration. Why four hours? Clair normally has eight working hours per day on these particular days (as determined by her resource calendar). She was assigned to this task at 50% assignment units, however, so the resulting scheduled work is only four hours per day.

You want to increase Clair Hector’s work on the last two days of this task so that she will work full-time on it. To accomplish this, you will manually edit her assignment values.

8. In the timescaled grid in the right pane of the Project window, select Clair Hector’s four-hour assignment for Wednesday, March 5.

9. Type 8h, and then press the key.

10. In Clair’s assignment for Thursday, type 8h, and then press .

Clair is now assigned eight hours per day on these days. Project displays a contour indicator in the Indicators column showing that a manually edited contour has been applied to the assignment.

Here are a few more capabilities that you can apply in a usage view:

• In addition to manually editing work values at the resource level as you did above, you can also edit work values at the task level. When you change a work value at the task level, Project adjusts the resulting work value per resource in accordance with each resource’s units value on that assignment. For example, assume that on a specific day, two resources were assigned four hours each to a task that had a total work value of eight hours. If you then change the total work on the task for that day to 12 hours, Project will increase the work per resource from four to six hours.

• You can split a task in the Gantt Chart view to account for an interruption in the task, as you did in Chapter 7. You can also split a task in the Task Usage view by entering “0” work values in the timephased grid for the date range you want. To preserve the total work on the task, you should add the same amount of work to the end of the task as you subtracted with the split. For example, assume that a task starts on Monday and has eight hours total work per day for four days. Its work pattern (in hours per day) is 8, 8, 8 and 8. You interrupt work on the task on Tuesday and then add those eight hours to the end of the task (in this case, Friday). The new work pattern would be 8, 0, 8, 8, and 8.

• When editing values in the timephased grid, you can work with the cells somewhat like you might work in an Excel worksheet-you can drag and drop values and use the AutoFill handle to copy values to the right or downward.
