Critical defects are significant flaws in a product or system that can lead to serious issues, such as safety hazards or major operational failures. These defects often require immediate attention and resolution, as they can impact the overall functionality and reliability of the item. Identifying critical defects is essential in quality control processes to ensure that products meet safety and performance standards. In industries like manufacturing and software development, critical defects can result in costly recalls or system outages. Organizations often implement rigorous testing and quality assurance measures to detect these defects early. Addressing critical defects promptly helps maintain customer trust and ensures compliance with regulations related to safety standards and product quality.
