It is nothing but APR.

For RM, u can incorporate the same with the Performance of Vendor. Normally we are not analyze RMs for each and every lot, when we get from a approved vendor.

U can incorporate
RM / PM
Production performance (details of all batches mfd.)
Production equip. performance
Deviations
Change controls
Inprocess data
QC data
Stability
Yield
Rejections
Reworks
complaints
Recalls

Along with trend charts u can use Mean charts and Range evaluation.

Dear forum,

Retrospective PV can only be accepted for established process espescially for non-sterile products. All information should include most information as normal validation process.

RM and PM information is considered important during assessment. Different RM manufacturer will supplied different type of RM even though it was from approved supplier. You should explain and justify it in risk assessment.

Then by using ‘Process Capability Index’ and ‘Sigma Calculation’ you should prove the data and critical parameters are consistent and capable to be produced consistently.
