The Cost Performance Index (CPI) is calculated to be 0.8. Your project sponsor wants to know what CPI the project must perform at for the last 50 percent of the project for the project to come in at budget. The answer, of course, is 1.2. The numbers used in this scenario allow the answer to be logically estimated.

The new project data is 46 percent of the work is complete, and CPI is 0.78 The project work is expected to continue, from a cost standpoint, to the project end similar to the first 46 percent What CPI must the project perform at over the last 54 percent of the work for the project to come in at budget?
