How does the IA handle data integrity when multiple technicians are involved in a single task?

• A. Verify each step is completed per approved data, review the overall result, and ensure final sign-off reflects the complete work.
• B. Allow each technician to sign off independently without cross-check.
• C. Delegate all verification to the lead technician.
• D. Review only the final outcome, not each step.

Answer: (A)

Data integrity with multiple technicians is protected by confirming every step against approved data and by documenting progress so the complete work is verifiable. When several people are involved, each action must be performed per the approved instructions and then reviewed as part of the overall result. The final sign-off should accurately reflect the entire task, showing that all steps were completed and properly verified, not just the last action. This approach prevents omissions or deviations from being hidden in the process. Signing off independently without cross-checking can let errors slip through, delegating verification to one person creates a single point of failure, and only reviewing the final outcome misses intermediate steps where mistakes can occur.
