Implement AUDIT TRAIL 21CFR in FACTORYTALK OPTIX

What does this application do?

21 CFR Part 11 is a regulation issued by the U.S. Food and Drug Administration (FDA) in 1997. It establishes the criteria under which electronic signatures and records are accepted as legal equivalents to handwritten signatures and paper records in the life sciences industry (pharmaceutical, biotechnology, medical device, etc.).

Its objective is to ensure that computer systems used in manufacturing, quality control, and regulatory documentation meet standards of:

• Authenticity
• Integrity
• Confidentiality
• Non-repudiation (a signature cannot be rejected as non-genuine)

Implementing 21 CFR is useful because it:

• Replaces paper: Reduces storage, printing, and physical handling costs.
• Streamlines processes: Enables legally valid digital workflows.
• Efficient auditing: Facilitates tracking of actions and changes in electronic records.
• Regulatory compliance: This is mandatory for companies operating under the FDA.
