Process Validation stages continued process verification

Third stages in Process Validation is Continued Process Verification, Some points in process validation during continued process verification are as follows, So let us see one by one all the points:

The main goal of continued process verification in process validation is to ensure that the process remains in a state of control during manufacturing of commercial products.

The data is collected and evaluated in order to determine process variability.

During this process the problems are identified if any and the corrective actions are suggested and implemented. 

The data of process trends, in-process materials, finished products and the quality of the incoming materials or other components are checked.

Statistical and qualitative tools are used in order to check any variations.

Routine sampling and continuous monitoring  of the particular product or particular process is done.
