Schedule Performance Index (SPI) in Project Management
The document discusses the Scheduling Performance Index (SPI) and its interpretation, relating to the performance of a project over time. It provides specific calculations for Activity A with varying levels of progress, indicating whether the project is ahead or behind schedule based on earned value (EV) and planned value (PV). Different SPI values are used to assess project status, emphasizing the importance of careful measurement in project management.
