A particular project is scheduled to complete in Week 50 at a budgeted cost of $150,000. As of Week 30 , an earned value chart is prepared to present the project progress as below: a. Calculate schedule, cost and time variances, as well as schedule and cost performance indices for Week 30. Then use this information to comment on the project progress at Week 30 (status date). b.

Also estimate the revised project completion date. Will the project complete sooner or later than the planned completion date, and by how many weeks
