How Do You Deal with Legacy Computerized Systems?
You are probably familiar with this issue. Your company still relies on old computerized systems. These systems are often critical for operations or provide valuable process data and analysis. Yet, when it comes to their validation status, there is often uncertainty.
Let’s be honest: deep down, you may already know the answer. The system is no longer fully compliant.
So, what should you do?
1. Understand the Current Situation
The first step is awareness. Start the discussion about the system and assess its current status.
Ask yourself:
- Is the system truly non-compliant?
- Which requirements are no longer being met?
- What are the GMP-critical gaps? Don’t miss the data generation integrity and regulatory complliance risks here.
- What are the potential business and compliance risks?
A structured assessment will help distinguish assumptions from facts and provide a realistic picture of the situation.
2. Determine the System's Business Value
Next, define the primary purpose of the system.
- Which processes does it support?
- What GMP-critical functions does it perform?
- Is replacement a realistic option?
- Is the system so unique, complex, or costly that replacement will take a long period?
Understanding the system’s role helps determine the most appropriate strategy going forward.
3. Develop a Risk-Based Mitigation Plan
If replacement is not immediately possible, identify all gaps and issues in detail. For every issue, define an appropriate mitigation measure.
Consider:
- User-related controls
- Technical solutions
- Procedural controls
- Additional monitoring activities
- Paper-based supporting evidence where appropriate
Think creatively, but remain practical. Solutions must be realistic, sustainable, and acceptable from a compliance perspective.
4. Document
Implement the mitigation measures and ensure they are properly documented.
Good documentation demonstrates that the risks are understood, assessed, and mitigated. Be realistic about the final outcome.
5. Be Realistic
Some systems are simply too old, rigid, or unsupported to be fully remediated.
In those situations:
- Clearly document all known deficiencies
- Mitigate risks as far as reasonably possible
- Increase oversight where needed, for example through more frequent periodic reviews
- Develop and execute a roadmap for system replacement
Remember: not every legacy system can be made fully compliant again, but every organization can make informed, risk-based decisions about managing it.
6. Easier Said Than Done
Writing about legacy systems is much easier than dealing with them in practice. Assessing risks, defining mitigations, balancing compliance expectations, and planning replacements can be challenging, especially when operations depend on the system every day.
