Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident related to fast-draining iPhone batteries due to the Facebook app has happened again within the same organization. The article mentions that Facebook was accused of using background tricks to stay active even when not being used, leading to battery drain issues. Although Facebook admitted bugs existed and fixed them, questions about the app's impact on battery life remained [40942]. (b) The software failure incident related to battery drain caused by the Facebook app has also been reported with the Android version of the app. Similar concerns about Facebook's Android app led to the discovery that deleting the app saves up to 20% of a phone's battery. This indicates that the issue of excessive battery consumption by the Facebook app is not limited to iOS devices but also affects Android devices [40942].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase can be seen in the case of the Facebook app causing fast-draining iPhone batteries. The article mentions that Facebook was accused of using background tricks to stay active even when it wasn't being used, leading to battery drain issues. Facebook admitted bugs existed in the app and fixed them, but questions about the app's impact on battery life remained [40942]. (b) The software failure incident related to the operation phase is evident in the discovery that deleting the Facebook app on Android devices saves up to 20% of the phone's battery. Similarly, on iPhones, uninstalling the Facebook iOS app and switching to Safari can save up to 15% of iPhone battery life. This indicates that the operation of the Facebook app itself was contributing to excessive battery consumption on mobile devices [40942].
Boundary (Internal/External) within_system (a) within_system: The software failure incident related to the Facebook app causing fast-draining iPhone batteries was primarily due to bugs within the app itself. Facebook admitted that bugs existed in the app and fixed them, but the issues with battery drainage persisted [40942]. The article mentions that uninstalling the Facebook app and using the social network in Safari instead resulted in significant battery life improvements, indicating that the problem originated within the Facebook app's design and functionality.
Nature (Human/Non-human) non-human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident related to fast-draining iPhone batteries caused by the Facebook app was attributed to bugs and background tricks within the app itself. Facebook admitted that bugs existed and fixed them, but questions about the app's impact on battery life remained [40942]. (b) The software failure incident occurring due to human actions: The article does not provide specific information about the software failure incident being directly caused by human actions.
Dimension (Hardware/Software) hardware, software (a) The software failure incident related to hardware: - The article discusses how Facebook's iOS app was causing fast-draining iPhone batteries, indicating a hardware-related issue where the app was impacting the battery life of the devices [40942]. (b) The software failure incident related to software: - The article mentions that Facebook admitted bugs existed in their app, which were fixed, but questions about the app's impact on battery life remained. This indicates a software-related failure where bugs in the app were causing issues [40942].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident related to the Facebook app causing fast-draining iPhone batteries was non-malicious. The issue was attributed to bugs in the app that caused it to use background tricks to stay active even when not in use, impacting battery life [40942]. Facebook admitted the existence of bugs and worked to fix them, indicating that the failure was not due to malicious intent but rather unintended consequences of the app's behavior.
Intent (Poor/Accidental Decisions) poor_decisions, accidental_decisions The software failure incident related to the Facebook iOS app causing fast-draining iPhone batteries can be attributed to both poor_decisions and accidental_decisions. 1. Poor_decisions: The incident involved poor decisions by Facebook in the design and implementation of their iOS app. The app was accused of using background tricks to stay active even when not in use, leading to excessive battery drain. Facebook admitted to bugs in the app and fixed them, but questions about the app's impact on battery life persisted [40942]. 2. Accidental_decisions: On the other hand, the discovery that deleting the Facebook app could save up to 20% of a phone's battery was more of an accidental decision or unintended consequence. Users found that uninstalling the app and using Facebook in Safari instead resulted in significant battery savings, which was not the intended design of the app [40942].
Capability (Incompetence/Accidental) development_incompetence (a) The software failure incident related to development incompetence is evident in the case of Facebook's iOS app causing fast-draining iPhone batteries. The app was accused of using background tricks to stay active even when not in use, leading to significant battery drain issues. Facebook admitted to bugs existing in the app and had to fix them to address the problem. Despite the fixes, questions remained about the app's impact on battery life, indicating a failure in the development process that allowed such issues to persist [40942]. (b) The software failure incident related to accidental factors is seen in the discovery that deleting the Facebook app on Android devices saves up to 20% of the phone's battery. This accidental revelation led to further investigation into the impact on iPhone battery life, where it was found that uninstalling the Facebook iOS app and using Safari instead can save up to 15% of iPhone battery life. This accidental discovery highlights how a simple action like deleting an app can have unintended positive consequences on device performance [40942].
Duration temporary The software failure incident related to the impact of Facebook's iOS app on iPhone battery life can be categorized as a temporary failure. The incident was temporary because it was caused by specific factors introduced by the app's background tricks and bugs, which were later acknowledged and fixed by Facebook. The issue was not inherent to the app itself but rather due to specific behaviors and inefficiencies that were addressed [40942].
Behaviour value, other (a) crash: The articles do not mention any crash of the Facebook app causing a failure incident. (b) omission: The failure incident related to the Facebook app was not about omitting to perform its intended functions at an instance(s). (c) timing: The failure incident was not related to the system performing its intended functions correctly, but too late or too early. (d) value: The software failure incident related to the Facebook app was about the app impacting iPhone battery life due to background tricks and bugs, leading to fast-draining batteries [40942]. (e) byzantine: The articles do not describe the Facebook app behaving erroneously with inconsistent responses and interactions. (f) other: The software failure incident involved the Facebook app consuming significant battery life on iPhones due to background tricks and bugs, even when not in use, leading to concerns and impacting user experience [40942].
