Scenario A. A particular construction project has the following characteristics:

Task	Duration	Predecessor(s)
A	3	-
B	6	-
C	3	-
D	5	A
E	3	C
F	7	A
G	4	B, D, E

1. Determine the critical path.

2. Determine the expected duration of the project.

Scenario B. The budgeted cost to c.o.m.plete a particular project is $250,000. To date, the budgeted cost of work scheduled (planned Value) is $45,000, and the following work packages of the project have been c.o.mpleted or are in process:

Work Pkg.	Work Pkg. Budget	Reported % Complete	Actual Costs to Date	Planned Value	Earned Value
A	$15,000	100	$19,000	?	$15,000
B	11,000	100	14,000	?	11,000
C	14,000	50	7,000	?	7,000
D	20,000	10	2,000	?	2,000
Total	$60,000		$42,000	$45,000	$35,000

Now that tasks A and B are 100% c.omplete, and assuming that the work package achieved the technical/performance targets for these two work packages, how is the project doing?

3. What is the schedule variance? What does this result mean?

4. What is the cost variance? What does this result mean?

Scenario C. Take the data from scenario B and assume that the original schedule called for the project to be c.ompleted within seven months and that the performance for the remainder of the project is similar to the performance to date.

5. What is the estimated total cost at completion?

6. What is the estimated completion date?
