This video will help you understand end date variance in SmartPM.
End Date Variance
End date variance in SmartPM is the number of days the end date has shifted since the baseline. SmartPM let’s you see why the end date is set to that value.
The end date variance is calculated by looking at two factors: critical path delay and acceleration
End date variance variance = (Critical Path Delay - Acceleration)
Note: all day calculations in SmartPM are done in calendar days using full seven-day weeks on these calculations.
Critical Path Delay
Critical path delay in SmartPM is how actual progress to critical path work affected the project’s end date. It calculates how actually reported in place work moved the end date on the critical path. Slower than planned progress on the critical path will push the end date out.Better than planned work on the critical path will bring the end date in.
Future Acceleration
Future acceleration may also be called mitigation or recovery. Future acceleration in SmartPM is how changes to the remaining planned work have affected the end date. Often when there are delays, we try to recover or accelerate the remaining work to move the end date back in. Durations are shortened, logic ties are switched, and work is resequenced. Conversely, changes could be made to the plan side to add time and push the end date out. Adding extended change orders or time extensions, or future looking fragnets into the plan side of the schedule, could cause the end date to extend. In cases of where time is added to the schedule, SmartPM will represent this as negative acceleration with a negative number.
