It is more than a decade that EVM as one of the most essential principles of the science of project management, has given up its place to the newfangled method of "Earned Schedule", because of its deficiencies in showing the behaviour of projects. A method which in comparison with the previous methods, has the needed capability to concentrate on the topic "time" without analysing the actual cost and solved the problems of the schedule performance  index. However, the continual use of the method Earned Schedule showed that although its indexes in use have been efficient in the condition of projects, in spite of the basic expectation, the issue of forecasting the future is still one of the obsessions of the stakeholders. In this article, based on the identifying the defects of ES method in forecasting the future of the project, a new method named as " Forecasting at completion"  has been introduced which is being shown as FC. This method has introduced new parameters to managers and the results of using it show that it is more practical than the previous methods.
