TMN, Winter 2007: Measuring the accuracy of earned value/earned schedule forecasting predictors

In this article, published in 2007 in The Measurable News, the forecasting accuracy of various time predictors using the earned value and earned schedule methodology is compared and validated. Nine methods are compared and it is shown that the earned schedule based predictors outperform the traditional earned value based methods when predicting the final duration of a project in progress.
More information on this topic can be found in other articles on project control, such as articles on time forecasting (See ”Earned Value Management: Forecasting time”) as well as on evaluating the forecasting accuracy of these time predictors (See ”Predicting project performance: Evaluating the forecasting accuracy”).
