Consider the following information about a small project:

Task	Duration Estimates		ImmediatePredecessors
A	3	days	None
B	3	days	A
C	4	days	B
D	2	days	A
E	2	days	B & D
F	9	days	E & C

a. Identify the critical path.

• A-B-C-F

• A-D-E-F

• A-B-E-F

b. In the first table, identify the early start and early finish for each task. The table header of "Earliest completion" is the same as early finish. (Leave no cells blank - be certain to enter "0" wherever required.)

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.)
