Use this window to view earned value and other key indicators of project performance. Earned value is an objective measurement of how much work has been accomplished in a project, and improves on the 'normally used' spend plan concept (budget versus actual incurred cost) by requiring the work in process to be quantified. Earned value, planned value, committed value and used cost data provide an objective measurement of performance, enabling trend analysis and evaluation of cost estimate at completion within multiple levels of the project. No information can be manually updated in this window.
