What is meant by 'System Release' in clinical trial documentation?

• A. The formal approval and deployment of a system used in the trial.
• B. A review of data quality.
• C. Training for system users.
• D. The decommissioning of a trial system.

Answer: (A)

System Release is the formal authorization to move a system into production for use in the trial. It means the system has been validated, all required documentation is in place, access and security controls are set, configurations are finalized, and the system is officially deployed so trial staff can start using it to capture and manage data. This step precedes active use and is distinct from ongoing activities like data quality reviews, which happen after data is in the system; training is important but is a separate readiness activity, and decommissioning is about retiring a system, not releasing it for use.
