Unformatted text preview: ndow. We are now going to explain how to enter tasks using both the Gantt Chart View and the PERT Chart View. We will enter the task names and durations in Gantt Chart View and then specify their dependencies in PERT Chart View. The reasons we are entering these durations now is to show how Project expects to be used. We will show how to get around entering durations during task sequencing a little later in this section. To begin with, enter the first four tasks (shown here) and their durations in Gantt Chart View by typing them into the Task Name column and the Duration column and then pressing the Enter key. Or you can use your mouse to move down a row. Task Name Siteprep 1 Siteprep 2 Siteprep 3 Siteprep 4 Duration 5 12 13 13 Your screen should now look like Figure 7-2. Notice that for each task you enter, Project draws a task bar proportional in length to the task's duration to the right of the task data you entered. Now click on the PERT Chart View icon on the left side of the Gantt Chart View window. This will cause your screen to look like Figure 7 You may have to reduce the viewing size of the Pert Chart View in order to make it look like Figure 7 do this, select the Zoom option from the pull-down menu that appears when you click on the View button at the top of the Project window. Some of the boxes in the PERT Chart View are red, and some are black. The reason for this is that, without any further information, Project considers tasks 3 and 4 to be on the critical path . It does not yet have enough information to conclude that tasks 1 and 2 are also on the critical path. The concept of the critical path has not been explained yet, but it will be shortly. Now click on the first box (Siteprep 1), and, while holding the right mouse button down, drag the mouse until the cursor is over the second box (Siteprep 2). This will cause an arrow to TE Figure 7 -2. Entering tasks on a Gantt chart. AM FL Y
Team-Fly® Figure 7-3. The PERT chart screen showing entered tasks. be drawn from box 1 to box 2 as shown in Figure 7-4. By default, this causes Project to consider boxes 1 and 2 to be connected by a finish-to-start relationship, as defined in Chapter 2. In constructing the task sequencing for all the new tasks introduced in Chapter 6, we assumed that most of the dependencies were finish-to-start relationships. There are, however, a couple of start-to- start relationships in the sequencing. If you want to make one of the dependencies another type, such as a start-to-finish relationship, you can double-click on the arrow that depicts the dependency, and a Task Dependency window will appear that will allow you to choose one of the other dependency types. Also, you can repeat this process on this same task (Siteprep 1) to create other arrows (dependencies) to other tasks. Since there are now a total of 42 tasks, you probably do not want to take the time to enter all of them, although it is a good exercise for those who have the time to spare. Instead, we have included a list of all the tasks, their du...
