Billy is the project manager of the PQW Project and she has an assigned project budget of $655,000. Currently she is 80 percent complete with the project though she was scheduled to be 100 percent done by this date. She has spent $490,000 to date and other than the project schedule, which was delayed because of a vendor, the project is going well. What should Billy report as her schedule performance index for this project?
