Info

Using our rules we see that Task A has no predecessor (a—under PRED.) Therefore, we will insert a 0 into that cell as shown in Table 3-17 and calculate EF using our formula EF = :ES + Duration. Then move to task B (see Table 3-18). Task B is the same as task A, so repeat the procedure.

Now we can move down to task D. Task D has two predecessors—A and B. We want to make the ES of task D the maximum of the EF's of these two task. Looking at the data we want to make task D ES equal to the max of 5 or 3, so we take 5, as shown in Table 3-20

Repeat this procedure through all the task until you reach the last task as shown in Table 3-21. The project duration is then the maximum of all of the EF's or 22. Pass 2

Now we are ready to start Pass 2. We will begin in the lower-right LF in Table 3-22.

We will start with task G. Is there any task that has a G in the predecessor column? In this case, there is not. Therefore the LF for task G equals the
