Verifikációvalvalidációval

Verifikációvalvalidációval is a term that describes the intertwined processes of verification and validation, commonly employed in software development, engineering, and other fields. Verification focuses on ensuring that a product or system is built correctly, meaning it meets its specified requirements and design. This often involves reviews, inspections, and testing at various stages of development to confirm that the implementation accurately reflects the intended design and specifications. Essentially, verification answers the question, "Are we building the product right?"

Validation, on the other hand, concentrates on ensuring that the product or system built is the right product, meaning it meets the needs and expectations of its intended users or stakeholders. This typically involves testing the final or near-final product in its intended environment to confirm that it fulfills its purpose and solves the problem it was designed to address. Validation answers the question, "Are we building the right product?"

The processes are distinct but complementary. Without verification, a system might be built to spec but still not be what the user needs. Without validation, a system might meet user needs but be riddled with errors or not function as intended. Effective development processes integrate both verification and validation throughout the lifecycle to produce high-quality, fit-for-purpose outputs.
