You are managing a project and using the earned value method to manage the budget. You want to prevent the tendency for team members to inflate their "percent complete" estimates. What can you do to try to get the most accurate estimates?

Require all estimates to be approved by the head of the department.

Require an audit from a third-party to ensure accuracy.

None of these methods is appropriate

Keep work packages small in terms of scope and duration.

 

Answer D Keep work packages small in terms of scope and duration.

Explanation-Having each job unit small not only helps to predict the percentage of completion, but it also offers a more methodical approach to make the worker's progress at the end of the project readily visible. When the project is broken into broad units, so a small delay in the planned completion would be overlooked if it is currently far apart. Because of wider groups, the worker can also get bogged down in the process, which may lead to further unexpected delays. It is impossible to know how much work has been finished or has yet to be accomplished if the job packages are too big.
