PERT charts are also called Critical Path Management (CPM) or Critical Path Analysis (CPA) charts. The PERT chart shown above places the time to do a task, starting date, and ending date inside the task box. The horizontal axis has time in months and the vertical axis shows who will be doing the work.

If you haven't already done so, first download the free trial version of RFFlow. It will allow you to open any chart and make modifications.

Once RFFlow is installed, you can open the above chart in RFFlow by clicking on pert_html.flo. From there you can zoom in, edit, and print this sample chart. It is often easier to modify an existing chart than to draw it from scratch.

To draw this chart without downloading it, run RFFlow and click on the More Shapes button, click the Pert, CPM, CPA Charts stencil, and then click the Add Stencil button.
