Continuous Process Verification (What it takes for a rapid set up?)

ICH Q10 Guidance and Process Validation Guidance published by FDA in 2011 both emphasizes routine process monitoring and continued process verification (CPV) as an integral part and a third and final stage of process validation and its life-cycle management.






A nice and very detailed case study has been published by BPOG (Biophorum Operations Group) on how to implement CPV. Though this case study is very detailed, here below is summarized in a flow chart the steps involved in setting up CPV. This gives an idea of what procedures, tools and efforts needed to rapidly setup a CPV program at your organization.




For definitions of CPP, KPP and MP refer to our July 27, 2015 blog on SPC.

Steps 1 through 4 involves scientific judgement hence cannot be automated.  This will involve some initial lag time to establish a CPV program. However an efficient knowledge management platform can greatly help in rapidly identifying parameters to monitor and establishing trending techniques and can significantly help in reducing time of deployment.

Steps 5 through 11 require fair amount of labor and can become a daunting task to routinely monitor hundreds of parameters (especially for complex biologic products), investigate trends and keep updating/adjusting the control limits to keep a check on process variability and capability. Adding to this if your site/organization is a multi product commercial manufacturing site this activity become impossible to perform manually and keep up the frequent reviews of processes with limited resources (FTE's) available. Most of the steps from Steps 5 through 11 can easily be automated and a specially designed software tool for CPV purpose can prove to be great advantage having capabilities in terms of:

  • data integration and warehousing of all relevant historical process information
  • lot traceability and genealogy
  • performing correlations across process steps for quick troubleshooting
  • overlaying batch trends
  • templating specific process parameters for routine periodic trending
  • historical limits management
  • validated reporting

Few tools in this space have emerged recently (in last few years) catering to process data management and particularly CPV. 

Our ProcessPad platform is industry first completely web-based bioprocess data management software for rapidly deploying CPV in your organization. Contact us for more information at info@simplyfeye.com.

Statistical Process Control (SPC) and Continuous Process Verification (CPV)

Simplyfeye team is recently involved in a major project with a multinational pharma company where we are helping the company setup a process monitoring program of all its commercial manufacturing processes using our product ProcessPad.

We all know SPC is an important ingredient of CPV and a process control chart (as shown below) forms the central piece of the puzzle for SPC and any process monitoring program.

Here is how we help setup a Process Monitoring program.

Step 1: What to SPC?

Figure 2: Selecting parameters for routine monitoring

Step 2: What limits to apply?

Figure 3: Controlling the process within limits

Step 3: How to estimate control limits?

Figure 4: Statistical rules to estimate control limits

Step 4: How to identify a trend?


Step 5: How it all ends up in ProcessPad?

Figure 5: Outcome of Steps 1 through 4 in real life

Step 5 above shows how ProcessPad platform provides a tool set for rapidly deploying a process monitoring program for your continuous process verification efforts that can be easily validated in GMP environments with minimal efforts.
