TheSchedule Performance Index (SPI)is a key metric in Earned Value Management that measures how efficiently time is being used on a project.

Key Points:

SPI Calculation:

SPI = BCWP / BCWS

BCWP (Budgeted Cost of Work Performed) = $105,000

BCWS (Budgeted Cost of Work Scheduled) = $100,000

SPI = 105,000 / 100,000 = 1.05

Interpreting SPI:

An SPI greater than 1 indicates the project is ahead of schedule.

Conclusion:The correct answer isC. BCWP/BCWS = 105,000/100,000 = 1.05because this accurately reflects the schedule performance index for the project.
