Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) In the provided articles, it is mentioned that the issue of "insufficient privileges" during software updates is not unique to a specific software or organization. The error has been associated with various software programs distributed by different companies, including Apple, Microsoft, Skype, and Mozilla. For example, the article discusses how users encountered this error while updating iTunes, Office, Skype, Firefox, and Thunderbird. The incidents of software update failures related to insufficient privileges have occurred across different software products within the same organization (e.g., Microsoft Office) and across multiple organizations (e.g., Apple, Mozilla) [18851]. (b) The article also highlights that the problem of software update failures due to insufficient privileges is a common issue faced by users across different software applications and organizations. It mentions that the error has been associated with various software programs distributed by different companies, including Apple, Microsoft, Skype, and Mozilla. Users have reported encountering similar issues with different software products, indicating that the problem is not limited to a specific organization but is a widespread issue affecting multiple organizations and their products [18851].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the article where the Apple Software Update program encountered an issue while trying to install iTunes version 11.0.3 on a Windows 7 PC. The installer reported "insufficient privileges" despite the user being logged in as an administrator. This design flaw in the software update process led to the failure of the update [18851]. (b) The software failure incident related to the operation phase can be observed in the same article where users encountered "insufficient privilege" errors when trying to update various software programs like Office, Firefox, and Windows 8. These errors were associated with access-denied issues during the operation or use of the software, indicating failures introduced during the operation or misuse of the system [18851].
Boundary (Internal/External) within_system, outside_system From the provided articles, we can extract information related to the boundary of the software failure incident: (a) within_system: The software failure incident described in the articles is related to an update glitch with the Apple Software Update program while trying to install iTunes version 11.0.3 on a Windows 7 PC. The error message "insufficient privileges" was reported during the installation process, indicating an issue originating from within the system [18851]. (b) outside_system: The software failure incident also highlights the importance of keeping software up-to-date to combat malware attacks. Malware authors exploit weaknesses in software, and developers patch their programs to block such attacks. However, if software updates fail, it can leave systems less secure, indicating that external factors like malware attacks can also contribute to software failures [18851].
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: The article discusses a software update failure related to the Apple Software Update program encountering an "insufficient privileges" error while trying to install iTunes version 11.0.3 on a Windows 7 PC. This failure was not due to human actions but rather a glitch or fault within the software update process itself. The solution involved repairing the Apple Software Update program through the Programs and Features app, indicating that the issue was related to the software's functionality rather than human error [18851]. (b) The software failure incident occurring due to human actions: The article mentions that access-denied errors like "insufficient privilege" are common with various software updates, including Office, Firefox, and Windows 8. Suggestions provided by contributors include ensuring the user is running as an administrator and changing folder properties to allow everyone access to the update folder. These actions are related to human interactions with the software and system settings, indicating that human actions can contribute to software update failures [18851].
Dimension (Hardware/Software) hardware, software (a) The software failure incident occurring due to hardware: - The article discusses how computer malware authors exploit weaknesses in software, leading to software update failures that leave systems less secure [18851]. - It mentions a specific incident where the Apple Software Update program failed to install iTunes due to an "insufficient privileges" error, which was resolved by repairing the software update program [18851]. (b) The software failure incident occurring due to software: - The article highlights that software update failures can occur, mentioning issues like "insufficient privilege" errors associated with various software programs [18851]. - It provides examples of software update failures related to different programs like Office, Firefox, and Windows 8, indicating that such errors are common across various software distributions [18851].
Objective (Malicious/Non-malicious) malicious, non-malicious (a) The article mentions computer malware authors exploiting weaknesses in software to launch attacks, indicating a malicious intent to harm systems [18851]. (b) The article discusses software update failures that occur when attempting to install updates, such as the iTunes update glitch due to "insufficient privileges." These failures are non-malicious in nature, as they are not intentional but rather result from technical issues [18851].
Intent (Poor/Accidental Decisions) accidental_decisions Accidental_decisions: The software failure incident described in the article is related to accidental decisions or mistakes. Specifically, the failure occurred during an attempt to update iTunes on a Windows 7 PC, where the installer reported "insufficient privileges" despite the user being logged in as an administrator. The solution involved repairing the Apple Software Update program in Win7's Programs and Features app, indicating that the failure was not due to intentional poor decisions but rather an accidental issue during the update process [18851].
Capability (Incompetence/Accidental) development_incompetence (a) The article discusses software-update failures that occur when users encounter errors like "insufficient privileges" during the installation of updates. These failures are attributed to issues related to access permissions and privileges within the software and operating system environment. Users may face challenges in updating software such as iTunes, Skype, Office, Firefox, and Windows due to insufficient privilege errors. The need to repair or change folder properties to allow updates to proceed indicates a lack of professional competence in ensuring seamless software updates without encountering access-denied errors [18851]. (b) The article also mentions that software-update failures, such as the "insufficient privilege" error, are common and can be associated with various software programs like Office, Firefox, and Windows 8. Users may encounter accidental failures during software updates when they face issues related to access permissions and privileges, leading to errors that prevent the successful installation of updates. The accidental introduction of access-denied errors can result in failed software updates, requiring users to troubleshoot and make adjustments to folder properties to enable the update process to proceed [18851].
Duration permanent, temporary (a) The article discusses software update failures that are not as simple to diagnose and cure, indicating that some software failure incidents can be permanent due to contributing factors introduced by all circumstances [18851]. (b) The article also provides examples of specific software update failures that were resolved through repairs or changes in settings, suggesting that some software failure incidents can be temporary due to contributing factors introduced by certain circumstances but not all [18851].
