Free PMI Project Management Professional (PMP) Practice Question

The correct answer is that the project is behind schedule. The Schedule Performance Index (SPI) is a measure of schedule efficiency in Earned Value Management. It is calculated by dividing the Earned Value (EV) by the Planned Value (PV). An SPI of 1.0 indicates the project is exactly on schedule. When SPI is less than 1.0, it means the project is behind schedule. In this case, an SPI of 0.85 indicates that the project has only completed 85% of the work that was planned to be completed by this point in time. This suggests the project is running behind its planned schedule and may require corrective actions to get back on track. Conversely, an SPI greater than 1.0 would indicate the project is ahead of schedule.
