Given the following project network:

a-1. Identify the critical path.

• A-C-D-F

• A-B-D-F

• A-C-E-F

a-2. In this table, identify the earliest start and finish for each task. Note that the column header of "earliest completion" is the same as early finish. (Leave no cells blank - be certain to enter "0" wherever required.)

b. In this table, identify the late start, late finish, and slack for each task. Note that the task order is now in backward-pass order. Also note the table header of "Latest completion" is the same as late finish. As a reminder, Slack = LF - EF, or can also be calculated as LS - ES. (Leave no cells blank - be certain to enter "0" wherever required.)
