From Estimates to Actuals and Back: Using Historical Data to Estimate
1:20 PM - 1:55 PM
Using historical data to estimate future projects is one of the hallmarks of the Integrated Project Management Process Area. The presentation provides an example of establishing a comprehensive system to estimate the effort needed to develop a system based on size complexity and past actuals, and how to close the feedback loop with the actual project performance. The described system leverages enterprise project management solution based on MS Project Server to track the project performance with the precision needed to obtain data to conduct the estimate vs. actuals variance analysis that is used to calibrate the estimation model based on the actual project performance.
