1. Determine the critical path.
2. Determine the expected duration of the project.
Scenario B. The budgeted cost to complete
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 completed or are in process:
Work Pkg.
Work Pkg. Budget
Reported % Complete
Actual Costs to Date
Planned Value

Now that tasks A and B are 100% complete, 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
completed 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?
