What is performance threshold? Performance thresholds are conditions of activities. Once these conditions are met, further analysis and action is required.

Performance threshold examples:

Finish date variance threshold of -2:  It means activity can finish 2 days later than its planned finish date. If as per current status, it is finishing more than 2 days late, an action is required to prevent it from delaying further or to fast-track or crash activity to bring make it finish earlier.

Start date variance threshold of -1:   It means activity can start 1 day later than its start date.

Other thresholds could be set for SPI, CPI, Total Float, Free Float.  The schedule analyst, after discussing with stakeholders decide performance thresholds to use and their limits to set.
