Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident related to the iPhone 8 freezing, unexpected restarts, or not turning on is specific to Apple's iPhone 8 model. There is no mention in the provided article of a similar incident happening again within the same organization or with its products and services. Therefore, there is no evidence to suggest that this specific software failure incident has happened again at Apple. (b) The software failure incident related to the iPhone 8 freezing, unexpected restarts, or not turning on is specific to Apple's iPhone 8 model. There is no mention in the provided article of a similar incident happening at other organizations or with their products and services. Therefore, there is no evidence to suggest that this specific software failure incident has happened at multiple organizations.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase is evident in the article as Apple announced a repair program for the iPhone 8 due to issues such as random freezing, unexpected restarts, or not turning on. These issues were specific to some iPhone 8 phones produced between September 2017 and March 2018, indicating a design flaw or fault introduced during the development phase [76255]. (b) The software failure incident related to the operation phase is highlighted in the article as users were instructed to check if their iPhone 8 was eligible for a free repair by following specific steps, including locating the serial number and pasting it into Apple's webpage. This operational procedure indicates that the failure was also influenced by the operation or use of the system [76255].
Boundary (Internal/External) within_system (a) The software failure incident related to the iPhone 8 freezing, unexpected restarts, or not turning on is within the system boundary. This issue is specific to the iPhone 8 model and is not affecting other models like the iPhone 8 Plus or any other iPhone [76255]. Apple has acknowledged the problem and initiated a repair program to address the issue, indicating that the failure is internal to the iPhone 8 devices themselves.
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: - The article mentions that some iPhone 8 phones produced between Sept. 2017 and March 2018 may experience random freezing, unexpected restarts, or won't turn on. This indicates a software failure that is not directly caused by human actions but rather by inherent issues in the production process or software design [76255]. (b) The software failure incident occurring due to human actions: - The article does not provide any information indicating that the software failure incident was caused by human actions. It primarily focuses on the specific issue affecting iPhone 8 devices and the repair program initiated by Apple. Therefore, there is no evidence of human actions contributing to the software failure incident in this case [76255].
Dimension (Hardware/Software) hardware (a) The software failure incident occurring due to hardware: - The article mentions that some iPhone 8 phones produced between September 2017 and March 2018 may experience random freezing, unexpected restarts, or won't turn on. These issues are related to the hardware component, specifically the logic board in the iPhone 8 [76255]. (b) The software failure incident occurring due to software: - The article does not mention any specific software-related issues contributing to the failure incident. Therefore, it is unknown if the failure was due to software factors [76255].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 76255 is non-malicious. Apple announced a repair program for the iPhone 8 due to some phones experiencing random freezing, unexpected restarts, or not turning on. This issue is specific to the iPhone 8 model and is attributed to a potential fault in the logic board of the affected devices. Apple is offering a free repair program for eligible devices to replace the faulty logic board, indicating that the failure was not caused by malicious intent but rather a technical issue within the affected phones [76255].
Intent (Poor/Accidental Decisions) unknown The article does not provide specific information about the intent behind the software failure incident related to the iPhone 8 repair program. Therefore, it is unknown whether the failure was due to poor decisions or accidental decisions.
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not mentioned in the provided article [76255]. (b) The software failure incident related to accidental factors is evident in the article [76255] where Apple announced a repair program for the iPhone 8 due to issues such as random freezing, unexpected restarts, or failure to turn on. These issues were not intentional but occurred accidentally during the production of some iPhone 8 phones between September 2017 and March 2018.
Duration temporary The software failure incident related to the iPhone 8 mentioned in Article 76255 is temporary. The issue with some iPhone 8 phones experiencing random freezing, unexpected restarts, or not turning on is specific to devices produced between September 2017 and March 2018. Apple has announced a repair program for these affected devices, indicating that the failure is not permanent but rather temporary and limited to a specific range of production dates [76255].
Behaviour crash (a) crash: The software failure incident mentioned in Article 76255 involves iPhones experiencing random freezing, unexpected restarts, or not turning on. These behaviors indicate a crash where the system loses its state and fails to perform its intended functions [76255].
