SPI Help

Hello,

I have a Change Order on my project ( 100 hrs). How are these hours captured in SPI? Or are Changes not factored in to SPI calculations?

 

Thanks!

Hi Veronica,

BCWS is budgeted cost of work scheduled, this is planned value. If you had a compensaton event/approved change, this would need to be reflected in your Key Dates and in the Prices. Effectively you would need to take a copy of your baseline, implement the changes there too, and this would become your performance measurement baseline.

Hello, how would his affect my SPI if a projects planned value doesn’t change? My understanding is SPI= Earned Value/ Planned value.. where the “planned value” is set when you baseline?

Thx

Hi Veronica,

I'm assuming these additional 100 hours are for future works and your client isn't arguing the work should have started already? In which case the additional labour would be a compensation event and, when approved, affect your ETC and remaining BCWS which would influence your future values of SPI but wouldn't affect any previously reported SPI values.

Schedule Performance Index which measures how you are performing against the palnned schedule. It is a ratio of earned value against the planned value. An SPI of 1 means you are on schedule less than 1 means you are behind schedule and greater than 1 means that you are ahead of schedule.
