What aspect is not addressed during Factory Acceptance Testing regarding system functionality?

• A. Interaction between components
• B. Identifying potential faults
• C. Testing safety mechanisms
• D. Performance under untested conditions

Answer: (D)

During Factory Acceptance Testing (FAT), the primary focus is on validating that the system meets the specified functional and safety requirements as per the design documents and contractual obligations. While interaction between components, identifying potential faults, and testing safety mechanisms are all essential aspects of this testing stage, the evaluation of a system's performance under untested conditions typically falls outside the scope of FAT. FAT is performed using predefined test cases based on known configurations and expected operating scenarios. It is designed to ensure that the system operates correctly according to its specifications under normal and anticipated conditions. Testing performance under untested conditions would be more characteristic of operational testing or reliability testing, which may be conducted later in the development lifecycle or during field testing. Thus, this aspect is not a primary concern during FAT, making it the correct answer.
