Analysis of earned value of computer system Project manager's calculation problem

Earned value method is also called the winning value method or the deviation analysis method. Earned value analysis is a method used in project implementation, and it is an effective method to control the project schedule and cost comprehensively.
The core of earned value method is the comprehensive measurement of project target, completion status and resource cost at any time. Conversion of progress to currency, or labor, engineering quantities such as: steel tons, cement cubic meters, the number of tubes or pages of documents.
The value of the earned value method is to measure the progress and cost of the project in a comprehensive way to accurately describe the status of the project. Another important advantage of the earned value method is that it can predict the time lag and cost overrun of the project, and take corrective action to provide effective means for project management and control.

Basic concepts of Earned value Analysis formula:

1. Planned value PV:PV is the budgeted cost of work that is scheduled to be completed by an activity or WBS element as of a specified point in time.

2. Earned value Ev:ev is the budgeted cost of work that has actually been completed in a fixed period of time, the progress activity or the WBS element.

3, the actual cost ac:ac is in a fixed period of time, the implementation of the progress activities or WBS elements of the actual total cost of the work. To calculate the AC value, it must be ensured that the calculation aperture is consistent with the calculation of PV and EV (e.g., the total cost, including the number of hours, direct costs, or indirect costs).

The Earned value analysis formula organizes the following data:
