Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident having happened again at one_organization: The article does not mention any previous occurrences of similar incidents within Apple or with its products and services. Therefore, there is no evidence of this specific software failure incident happening again within the same organization. (b) The software failure incident having happened again at multiple_organization: The article does not mention any previous occurrences of similar incidents at other organizations or with their products and services. Therefore, there is no evidence of this specific software failure incident happening again at multiple organizations.
Phase (Design/Operation) design (a) The software failure incident related to the design phase is highlighted in the article. The iOS 16.0.3 update by Apple addresses bugs on iPhone 14 models, including issues with delayed or undelivered incoming calls and notifications, low microphone volume during CarPlay phone calls, camera problems like slow launch speed or mode switching, and a Mail app crash caused by a malformed email. These issues indicate failures introduced during the system development or updates [134202].
Boundary (Internal/External) within_system (a) within_system: The software failure incident addressed in the article is within the system. The iOS 16.0.3 update released by Apple specifically targets bugs and issues within the iPhone 14 models and the Mail app, indicating that the failures originated from within the system itself [134202].
Nature (Human/Non-human) non-human_actions (a) The software failure incident related to non-human actions in this case includes bugs on some iPhone 14 models such as delayed or undelivered incoming calls and notifications, low microphone volume during CarPlay phone calls, camera issues like slow launch speed or spontaneously switching between camera modes, and an issue where a malformed email could cause the Mail app to crash. These issues were addressed in the iOS 16.0.3 update released by Apple [134202]. (b) The software failure incident related to human actions is not explicitly mentioned in the provided article.
Dimension (Hardware/Software) hardware (a) The software failure incident related to hardware in this case is the low microphone volume during CarPlay phone calls on some iPhone 14 models, as mentioned in Article 134202. This issue is a result of hardware-related factors affecting the software functionality.
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident mentioned in Article 134202 is non-malicious. The update, iOS 16.0.3, addresses bugs on iPhone 14 models and other general issues, such as delayed or undelivered incoming calls, low microphone volume during CarPlay phone calls, camera issues, and a problem with the Mail app crashing due to a malformed email. These issues are not caused by malicious intent but rather by unintentional software bugs and glitches. [134202]
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to the iOS 16.0.3 update for iPhone 14 models can be attributed to poor_decisions. This is evident from the fact that the update addresses bugs such as delayed or undelivered incoming calls, low microphone volume during CarPlay phone calls, camera issues like slow launch speed, and spontaneously switching between camera modes, as well as a Mail app crash caused by a malformed email. These issues indicate that there were poor decisions made during the development or testing phases that led to these bugs [134202].
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not mentioned in the provided article [134202].
Duration temporary The software failure incident mentioned in Article 134202 is temporary. The article discusses specific bugs and issues that were addressed in the iOS 16.0.3 update, such as delayed or undelivered incoming calls, low microphone volume during CarPlay phone calls, camera issues, and a Mail app crash caused by a malformed email. These issues were not permanent but rather specific to certain circumstances or conditions on the affected iPhone 14 models.
Behaviour crash, value (a) crash: The article mentions an issue where a malformed email could cause the Mail app to crash [134202]. (b) omission: No specific mention of omission-related software failure incidents in the provided article. (c) timing: No specific mention of timing-related software failure incidents in the provided article. (d) value: The article mentions issues such as delayed or undelivered incoming calls and notifications, low microphone volume during CarPlay phone calls, camera problems like slow launch speed or switching between camera modes, which can be categorized as failures due to the system performing its intended functions incorrectly [134202]. (e) byzantine: No specific mention of byzantine-related software failure incidents in the provided article. (f) other: The article does not provide information on any other specific behavior of the software failure incident.
