At what stage in a Project, the monitoring of SPI should be stopped,
1. is it after the baseline program completion date is over, but still with works ongoing in delay.
2. or earlier, noticing that project is in significant delay and will not meet target.

When it is easier to do a resourced contract close out list (inc snagging). Use JIRA (or similar) and burn down those actions!
Traditional SPI becomes increasingly unreliable after the mid point of the project - certainly in the last third as it trends back towards 1.0. It is also a relatively meaningless number all changes in SPI can tell you is there has been as change in the values used to calculate the ratio.
If you are looking for a realistic projection of completion based on Earned Value Management (EVM) data, consider using Earned Schedule (ES) the concept has been around for nearl 20 years now and the tools are free to access and use. All you need to to transpose your EVM data into the calculator.
