Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Hi,

SCHEDULE PERFORMANCE INDEX (SPI) – the ratio of work performed (earned value or BCWP) to work scheduled (planned value or BCWS).

COST PERFORMANCE INDEX / INDICATOR (CPI) – the ratio of earned value to actual costs (CPI = BCWP/ACWP). A value greater than 1 indicates that costs are running under budget. A value less than 1 indicates that costs are running over budget. Often used to predict magnitude of a possible cost overrun by dividing it into the original cost estimate (original cost estimate / CPI = projected cost at completion).
