Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident having happened again at one_organization: The article [118650] discusses the release of iOS 15 beta by Apple and highlights various known bugs and issues in the software. This indicates a recurring pattern of software issues with Apple's beta releases, where users are warned about potential problems and advised not to install the beta on their primary devices due to bugs. The article mentions specific problems such as Finder becoming unresponsive, camera issues, CarPlay connectivity problems, files quitting unexpectedly, Find My network issues, home screen widget problems, and SharePlay unavailability in the iOS 15 beta. Therefore, it can be inferred that Apple has experienced software failure incidents with its beta releases in the past, as indicated by the cautionary approach and the list of known bugs provided in the article. (b) The software failure incident having happened again at multiple_organization: There is no information in the provided article to suggest that the software failure incident discussed has happened again at multiple organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article [118650]. It discusses the iOS 15 public beta released by Apple and highlights various known bugs and issues in the software. For example, the article mentions problems such as Finder becoming unresponsive, camera issues like live text being unavailable, and unexpected results in Panorama mode when the iPhone is in Low Power mode. These issues indicate failures introduced during the development phase of the software, as they are related to bugs and glitches in the system that need to be addressed by Apple through workarounds or updates. (b) The software failure incident related to the operation phase can also be observed in the same article [118650]. For instance, the article mentions connectivity issues with CarPlay when sharing the screen in a SharePlay session, files quitting unexpectedly when choosing to open in a new window, and problems with the Find My network feature. These issues are more related to the operation or usage of the software rather than inherent design flaws, indicating failures introduced during the operation or misuse of the system.
Boundary (Internal/External) within_system (a) within_system: The software failure incident mentioned in the articles is primarily due to bugs and issues within the iOS 15 public beta software released by Apple. The article highlights various known bugs and problems within the iOS 15 beta, such as Finder becoming unresponsive, camera issues, CarPlay connectivity problems, files quitting unexpectedly, Find My network issues, home screen widget problems, and SharePlay unavailability. These issues are all internal to the software system and are part of the beta testing phase to identify and fix bugs before wider launches [118650].
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: - The article discusses various bugs and issues present in the iOS 15 public beta, such as Finder becoming unresponsive, camera problems, CarPlay connectivity issues, files quitting unexpectedly, Find My network issues, home screen widget problems, and SharePlay unavailability. These issues are examples of software failures caused by non-human factors like bugs and glitches [118650]. (b) The software failure incident occurring due to human actions: - The article does not mention any software failure incidents caused by human actions.
Dimension (Hardware/Software) hardware, software (a) The software failure incident occurring due to hardware: - The article mentions a specific issue related to the Finder becoming unresponsive when installing the iOS 15 public beta using Restore Images, which is a hardware-related problem [118650]. (b) The software failure incident occurring due to software: - Various software-related issues are highlighted in the article, such as camera problems, CarPlay connectivity issues, files quitting unexpectedly, Find My network problems, home screen widget problems, and SharePlay unavailability. These issues are all related to software bugs and glitches in the iOS 15 beta release [118650].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident mentioned in the articles is non-malicious. The issues highlighted in the iOS 15 public beta are related to known bugs and problems that users may encounter while testing the beta version of the software. These issues include Finder becoming unresponsive, camera problems, CarPlay connectivity issues, files quitting unexpectedly, Find My network problems, home screen widget problems, and SharePlay unavailability. Apple has provided workarounds for some of these issues, indicating that they are not intentional but rather unintended consequences of using a beta version of the software [118650].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to the iOS 15 public beta can be attributed to poor decisions made by users who choose to download and install beta software on their primary devices despite Apple's warning against it. Apple explicitly mentioned that they do not recommend downloading a beta version of any software on your primary device due to bugs, and users should only download the public beta if they have a secondary device for testing [118650]. This indicates that the failure was influenced by poor decisions made by users who did not follow Apple's recommendations.
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the iOS 15 public beta release by Apple. The article mentions that Apple disclosed a variety of known bugs in its iOS 15 release notes, which is pretty standard for beta releases. It also advises against downloading beta versions on primary devices due to bugs and recommends using a secondary device for testing [118650]. This indicates that the software failure incidents in the beta version were a result of development incompetence leading to the presence of various bugs and issues. (b) The software failure incident related to accidental factors is highlighted in the article discussing problems in the iOS 15 public beta. For example, issues like Finder becoming unresponsive, camera problems, CarPlay connectivity failures, files quitting unexpectedly, and Find My network issues are mentioned. These issues are not intentional but are accidental side effects of using the beta version, indicating software failure due to accidental factors [118650].
