In addition, an electronic signature should be attached to each document, so that it can be traced back to the original author.

It is important for manufacturers to understand the details of this requirement, including how to accurately document time and date stamps, issue roles and permissions, and ensure that there is a secure audit trail in place. Furthermore, digital security protocols must be implemented in order to guarantee the accuracy of the records. These may include user authentication, password protection, and encryption measures.

Finally, according to Part 11, all electronic records must be reviewed, verified, and authenticated before being filed. This helps to ensure accuracy and completeness of the records, providing vital evidence for compliance.

Detailed Requirements for System Validation

Manufacturers must ensure that their systems meet the validation requirements of 21 CFR Part 11 in order to comply with the regulations. System validation is the process of ensuring that systems are functioning properly and effectively to handle and store data according to the requirements set out in Part 11. Manufacturers will have to demonstrate that their systems meet these requirements both technically and operationally.

For a system to be validated it must:

  • Be documented and regularly maintained
  • Follow specific user requirements
  • Maintain accurate records of all activities
  • Verify that electronic signatures and records generated are reliable and trustworthy
  • Include protection from unauthorized access, alteration or deletion of data

Validation should include testing to prove that the system is working as expected and any errors are quickly identified and fixed. Manufacturers should also ensure that the test scenarios are sufficient to cover all aspects of the system. The tests should also be performed by qualified individuals to provide evidence that the system is meeting the requirements of 21 CFR Part 11.

Manufacturers are required to keep records of any changes made to their systems and ensure that the changes are compliant with Part 11. They should also have clear policies and procedures in place to ensure that their systems are validated to the applicable standards.
