Quality Indicator

May I know what SPI and CPI stand for?

SPI is Schedule performance index
CPI is Cost performance index

Budget	planned costs across a specified time period; the project’s estimated costs
BCWS	Budgeted Cost for Work Scheduled to be completed within a given time period; [Budget] X [percent of the duration to the current date]; planned costs (budget) up to the current date
ACWP	Actual Cost of Work Performed during a given time period; money spent up to the current date
BCWP	Budgeted Cost for Work Performed; Earned Value; the dollar amount of work that was actually accomplished; [Budget] X [percent complete]
Schedule Variance	SV = BCWP - BCWS; the value of what you have accomplished to date, versus what you planned to have accomplished to date
Cost Variance	CV = BCWP - ACWP; the value of what you have accomplished to date, versus what you have spent to date

Schedule Performance Index	SPI = BCWP / BCWS
Cost Performance Index	CPI = BCWP / ACWP

It seems nobody to use a programme for qulaity checking. The reason may due to the additional amount of quality related activity. As AA’s stated, how to reflect the re-work hour? Either a group of repeated or a proportional to the actual duration of the original. This make the network complex.
In P3, either user CDF to hold the proportion or introduce re-work activities. For P3e/c v4.0, may be simple just add one more issue/checklist against activity to create the Index.

The only time when I have seen something similar used was on site, where resourced programmes were being progressed, and the data exported and integrated with actual cost information in Excel.
Part of the validation routine involved reasons for cost and time changes from planned to actual results - this included quality performance (errors, etc.) as part of the report.
It could possibly be done by categorising resources spent into Useful, Rework, etc. - but that would mean updating the resource allocation when entering progress- never a good idea!
