What is the main purpose of verification and validation documentation?

• A. To show how each safety function fulfills its requirements.
• B. To note related effects and considerations impacting safe operation.
• C. To determine whether the safety system does what it is required to do.
• D. Both showing fulfillment of requirements and noting related effects.

Answer: (D)

The main purpose of verification and validation documentation encompasses both showing how each safety function fulfills its requirements and noting the related effects and considerations that impact safe operation. This dual focus ensures that a safety system is rigorously assessed not just on whether it meets its specified requirements, but also on how it interacts with other system components and the environment in which it operates. By documenting these aspects, an organization can demonstrate that the safety functions are not only designed to meet their intended goals but also are evaluated for any potential effects that could compromise safety. Verification involves confirming that the safety system design meets specified requirements, while validation focuses on whether the implemented system meets the operational needs and remains effective in its context. Together, these components provide a comprehensive understanding of the system's safety integrity and support the overall goal of achieving functional safety.
