EVM uses what the basic rules are, I believe that many inexperienced people are at a loss about this, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

In recent years, more and more project managers begin to use EVM in their projects. However, the introduction materials of EVM, including PMBOK, only explain the principle and calculation method of EMV, but do not mention the application method of practical work. Therefore, everyone is groping and moving forward at the same time, and there are many deviations in the application, which leads to the inability to accurately measure the team's workload, work efficiency and so on.

Here is a set of basic rules used by EVM to solve the above problems. The details are as follows:

Determine the average team efficiency indicator

This data can be derived from previous project experience or based on estimates of current projects.

Calculate man-hours

Estimate the workload of each task and calculate the work of the task based on the average efficiency of the team.

Assign the bearers and set the time limit

A person who assigns responsibilities to tasks. And determine the duration of the task according to the actual ability to undertake (note: keep the working hours the same)

Degree of completion entry

The degree of completion can be calculated in a variety of ways, including 20% at the beginning of the job, 80% after the job is finished, and 100% after checking, or according to the actual results, such as the proportion of lines of code, the proportion of parts, and so on. But make sure that the project-level approach is unified. As long as the granularity of the task is appropriate, the error of completion will not be too large.

Adjust the responsibility of the assignment

Tasks that have not been started can be adjusted directly. For the tasks that have already started, the tasks can be split according to the actual completion, and the total work value of all the tasks obtained by the split must be equal to the number of hours before the split.

Adjust the construction period

When adjusting the construction period, the working hours should be kept unchanged.

Adjust working hours

The working hours can be adjusted only if the amount of work does change. The adjustment of public hours means the adjustment of the scope of tasks and needs to reach a consensus with customers.

Performance analysis

Adhering to the above principles can ensure that the original function of EVM is to calculate the workload through the EV value and the work efficiency through the CPI.

Of course, we can also increase the actual salary information on the basis of the above information, in order to achieve a more comprehensive comparison.

After reading the above, have you mastered the basic rules of EVM? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
