What is conducted to determine a system's operational effectiveness and suitability?

• A. Verification test
• B. Developmental test
• C. Operational test
• D. Validation test

Answer: (C)

The correct answer is operational test, as this type of testing is specifically designed to evaluate a system's effectiveness and suitability in real operational environments. Operational tests assess whether the system meets the necessary operational requirements and performs as intended when used by the intended end-users under realistic conditions. This includes evaluating the system’s performance, user-friendliness, and reliability in scenarios that closely mimic actual operational use.

On the other hand, verification tests focus on confirming that a system was built correctly, aligning with its specifications. Developmental tests precede operational tests and are typically conducted to refine the design and detect defects early in the development cycle. Validation tests generally ensure that the product fulfills its intended purpose and meets the needs of stakeholders, but they may not encompass the broad operational context necessary for an effective evaluation of a system's overall performance in a real-world setting.
