What qualifies as a Major DFS?

A Major Defect of Functional Safety (DFS) is a significant issue that directly impacts the functionality, safety, or compliance with critical documents of a system. This means that if a defect qualifies as major, it could have detrimental consequences such as affecting the reliability of a product, endangering users, or leading to legal and regulatory violations. The definition suggests that the defect must relate to areas that are crucial for ensuring that the system operates safely and effectively, aligning with requirements and specifications.

Options that do not represent major DFSs focus on less critical aspects, such as insignificant details or easily reversible errors, which do not pose a serious risk to functionality or compliance. Therefore, only defects that have the potential for major repercussions categorize as Major DFS, emphasizing the importance of thorough quality assurance processes in identifying and addressing such defects.
