Earned value management (EVM, also called earned value analysis EVA) is a project management process that aims to identify performance problems early during the project execution. For an introduction please see earned value management at Wikipedia .
]po[ allows project managers to define the completion degree on the level of tasks in the Project -> Tasks page.
Based on these values and the other inputs to the process, ]po[ is capable to calculate all important outputs of earned value management automatically.
Currently, ]po[ uses the number of hours ("planned units") per task as the base for calculating earned value and percent completed. Future versions of ]po[ may support additional methods of calculating earned value.
