What does the Absence of Errors Fallacy imply?

The Absence of Errors Fallacy highlights the misconception that simply eliminating all visible defects or bugs from a system results in a perfectly functioning product. Therefore, while it's important to address bugs, the overall quality of software encompasses more than just defect resolution. Usability is vital to the user experience; even if a piece of software has no bugs, if it is difficult to use or does not meet the users' needs effectively, it can be deemed unsuccessful.

The fallacy suggests that a focus solely on defects without considering other critical quality aspects—like usability, performance, and user satisfaction—can lead to a false sense of confidence in the software's reliability. Thus, the most accurate interpretation of the Absence of Errors Fallacy is that usability and users' perceptions remain key components, regardless of how well the software has addressed its defects.
