Husky Air Assignment 9 – Chapter 9

Earned Value Analysis

Suppose that the testing of the Pilot Angels system has been outsourced to another organization called “Bug Busters.” This company is located in another country and has marketed themselves as specialists in software testing. You have signed a contract and sent them a copy of all the code, database tables, and files they need to fulfill their end of the contract. The total expected cost or expected budget at completion for this “subproject” is $12,000. The contract stipulates four payments must be made after completion of each of the four testing phases.

The first phase of testing went as planned, but due to some problems encountered, the second payment that you authorized was more than planned. The project manager in charge of testing has assured you that the few problems they encountered could not be helped and that she does not expect them to continue in the remaining phases. As a smart project manager, you have asked Bug Busters for a work breakdown structure (WBS) and an update of their progress because you are not so sure that these problems are atypical and may continue throughout the testing process.

Using the following information, conduct an earned value analysis to determine whether you believe the project will remain within its original planned budget of $12,000. Use a spreadsheet software package to determine the Estimate at Completion (EAC) for both typical and atypical variances.
