This invention relates to a method of portraying project schedule history in graphical form which facilitates a rapid assessment of the success of a project and its leaders from the standpoint of performance against schedule. More specifically, this invention relates to an “Estimated Time to Completion” chart that is plotted against “Date” in a two dimensional chart, and points on the chart are created at periodic checkpoints for the duration of the project. When the points are connected, a line is created which slants toward the “Date” axis and intersects that axis at the actual completion date. Partially-completed charts are useful at the periodic checkpoints for graphically illustrating how well the project team is holding to the schedule. Completed charts are useful in evaluating performance of team leaders and for creating incentives for timely performance of projects. Methods of adapting the charts to changes in project scope are included in this invention. The invention also relates to a method having steps for making the chart, both manually and by computer.
