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 All

In working with schedules and costs we use SPI and CPI as indexes for project controls.I am wondering if there is an index of quality,I was thinking like rework hours/budgeted hours what do you think,what is the quality approach for projects contrls.

Thanks in advance
AA

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!

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.

Budgetplanned costs across a specified time period; the project’s estimated costs
BCWSBudgeted 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
ACWPActual Cost of Work Performed during a given time period; money spent up to the current date
BCWPBudgeted Cost for Work Performed; Earned Value; the dollar amount of work that was actually accomplished; [Budget] X [percent complete]
Schedule VarianceSV = BCWP - BCWS; the value of what you have accomplished to date, versus what you planned to have accomplished to date
Cost VarianceCV = BCWP - ACWP; the value of what you have accomplished to date, versus what you have spent to date
Schedule Performance IndexSPI = BCWP / BCWS
Cost Performance IndexCPI = BCWP / ACWP

SPI is Schedule performance index
CPI is Cost performance index
