What does it indicate when the SPI is greater than 1?

When the Schedule Performance Index (SPI) is greater than 1, it indicates that the project team is completing more work than originally planned within the specified time frame. The SPI is a measure used in project management to assess the efficiency of time usage in a project. It is calculated by dividing the earned value (the value of work completed) by the planned value (the value of work scheduled to be completed).

An SPI greater than 1 signifies that the earned value exceeds the planned value, which means the project is ahead of schedule. This correlates with the understanding that the team is performing efficiently, delivering a higher amount of work than was anticipated for that point in time. This is a positive indicator for project progress and demonstrates effective time management and productivity by the project team.

While other options might suggest potential issues with the project, they do not align with what an SPI greater than 1 universally indicates in project management terms.
