Program validation ensures that software meets the needs and expectations of end-users or stakeholders by confirming it performs its intended functions accurately. Unlike verification, which checks adherence to specifications, validation focuses on real-world usability and functionality. It typically occurs after development through activities like testing, prototyping, and user feedback analysis to confirm the software aligns with client requirements and stakeholder expectations[1][2][5].
