ANALYZE THE TASKS Now study the tasks to determine the order in which they should
be performed. First identify all concurrent tasks, which are not dependent on other tasks.
In the example shown in Figure 7-31, Tasks 1, 2, 3, 4, and 5 are concurrent tasks, and
could begin at the same time if resources were available.
Other tasks are called dependent tasks, because they cannot be performed until one or
more earlier tasks have been completed. For each dependent task, you must identify specific
tasks that need to be completed before this task can begin. For example, you would want to
evaluate system requirements before you could prepare an RFP, so Task 6 cannot begin until
Task 3 is completed, as Figure 7-31 shows.
