The restoration of the functionality after fixing the bug indicates that it was an unintended issue rather than a result of deliberate decisions [18327]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article. Therefore, it is unknown if the bug resulting in the disappearance of Facebook's search history tool was due to a lack of professional competence by humans or the development organization.
(b) The software failure incident related to an accidental cause is evident in the article. Facebook acknowledged that a bug led to the sudden disappearance of its search history tool. The company mentioned that a technical glitch was responsible for the absence of the feature in the user settings area. This indicates that the software failure was accidental rather than intentional [18327]. |
| Duration |
temporary |
(a) The software failure incident in this case was temporary. Facebook acknowledged that a bug led to the sudden disappearance of its search history tool, and they mentioned that the bug has been fixed [18327]. The functionality was restored after the bug was addressed, indicating that the failure was not permanent. |
| Behaviour |
omission, other |
(a) crash: The software failure incident in the article is not related to a crash where the system loses state and does not perform any of its intended functions. The incident described a bug that resulted in the disappearance of a search history tool on Facebook, which was later fixed [18327].
(b) omission: The software failure incident can be categorized as an omission where the system omitted to perform its intended functions at an instance(s). The bug led to the absence of the search history tool in the user settings area, causing users to not be able to access their search history as intended [18327].
(c) timing: The software failure incident is not related to a timing issue where the system performs its intended functions correctly but too late or too early. The incident described a bug that affected the availability of a specific feature rather than the timing of its execution [18327].
(d) value: The software failure incident is not related to a value issue where the system performs its intended functions incorrectly. The incident described a bug that caused the disappearance of a feature, rather than the feature functioning incorrectly when accessed [18327].
(e) byzantine: The software failure incident is not related to a byzantine behavior where the system behaves erroneously with inconsistent responses and interactions. The incident described a bug that led to the absence of a specific feature, which was later fixed without mentioning inconsistent behavior [18327].
(f) other: The software failure incident can be categorized as an omission where the system omitted to perform its intended functions at an instance(s). The bug resulted in the sudden disappearance of the search history tool on Facebook, which was later fixed [18327]. |
