Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident related to high disk utilization in Windows 10 has been reported to have happened again within the same organization, Microsoft. The issue was specifically attributed to a firmware bug in some computers with solid-state drives [68264]. (b) The software failure incident of high disk utilization in Windows 10 has also been reported to have occurred with third-party programs like Google Chrome and Skype, as well as certain browser extensions, file-syncing services, and busy antivirus software scanning Windows during startup. This indicates that similar incidents have happened with products and services from multiple organizations beyond just Microsoft [68264].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase is evident in the article as it mentions a firmware bug in some computers with solid-state drives causing the disk usage to be at 100 percent during start-up in Windows 10 [68264]. This issue is attributed to a design flaw introduced during the development of the system. (b) The software failure incident related to the operation phase is highlighted in the article through various factors such as third-party programs like Google Chrome and Skype causing disk slowdowns, busy antivirus software scanning during startup affecting system responsiveness, and malware or spyware potentially hogging resources if a security program is not running [68264]. These operational factors contribute to the system's performance degradation and failure.
Boundary (Internal/External) within_system, outside_system (a) The software failure incident discussed in the articles is primarily within_system. The issue with Windows 10 causing the disk usage to spike to 100 percent is attributed to various internal factors such as firmware bugs in some computers with solid-state drives, software and services jamming up the system, problematic programs like Windows Desktop Search and SuperFetch, third-party programs like Google Chrome and Skype, browser extensions, file-syncing services, busy antivirus software, and potential malware or spyware hogging resources [68264].
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident related to non-human actions is attributed to a firmware bug in some computers with solid-state drives causing the disk utilization to reach 100 percent at startup in Windows 10 [68264]. (b) The software failure incident related to human actions includes factors such as third-party programs like Google Chrome and Skype, certain browser extensions, file-syncing services, busy antivirus software scanning during startup, and the presence of malware or spyware hogging resources [68264].
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware is attributed to a firmware bug in some computers with solid-state drives causing the disk utilization to reach 100 percent at startup [68264]. (b) The software failure incident related to software is linked to various factors such as third-party programs like Google Chrome and Skype, certain browser extensions, file-syncing services, busy antivirus software scanning, and potential malware or spyware hogging resources [68264].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in the articles does not indicate any malicious intent. Instead, it points to various non-malicious factors such as firmware bugs, software conflicts, and system resource issues causing the problem with Windows 10, leading to high disk utilization and system unresponsiveness [68264].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to the high disk usage in Windows 10 appears to be more aligned with poor_decisions, as it is attributed to various factors such as a firmware bug in some computers with solid-state drives, third-party programs like Google Chrome and Skype causing slowdowns, busy antivirus software scanning during startup, and potential malware or spyware hogging resources [68264]. These issues point towards a combination of factors that may have been influenced by poor decisions in software design, compatibility, and resource management.
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident related to development incompetence is evident in the article as it mentions a firmware bug in some computers with solid-state drives causing the disk usage to be at 100 percent, leading to unresponsiveness and system slowdowns [68264]. (b) The software failure incident related to accidental factors is also present in the article, where it discusses how other software and services, such as Google Chrome, Skype, browser extensions, file-syncing services, and busy antivirus software scanning, can inadvertently contribute to disk slowdowns and system responsiveness issues [68264].
Duration temporary (a) The articles mention that the software failure incident related to Windows 10's drive use being at 100 percent at start-up is not permanent. It is attributed to various contributing factors such as a firmware bug in some computers with solid-state drives, third-party programs like Google Chrome and Skype, certain browser extensions, file-syncing services, busy antivirus software scanning, and potential malware or spyware hogging resources. The incident is not a permanent failure but rather a temporary issue that can be addressed through troubleshooting steps and optimizations [68264].
Behaviour crash, other (a) crash: The software failure incident described in the article is related to a crash behavior. Users are experiencing a situation where their computers become unresponsive, and the disk usage is at 100 percent, making it impossible to open applications for a significant amount of time [68264]. (b) omission: The article does not mention any omission-related failures in the software incident. (c) timing: The software failure incident is not related to timing issues where the system performs its intended functions but at the wrong time. (d) value: The software failure incident is not related to the system performing its intended functions incorrectly. (e) byzantine: The software failure incident is not related to the system behaving erroneously with inconsistent responses and interactions. (f) other: The behavior of the software failure incident is mainly characterized by system unresponsiveness and high disk usage, leading to a crash-like scenario where users are unable to use their computers effectively [68264].
