| Recurring |
unknown |
(a) The software failure incident related to the Microsoft Teams bug blocking Android emergency calls has not been reported to have happened again within the same organization (Microsoft) or with its products and services. The incident appears to be an isolated case caused by an unintended interaction between the Teams app and the Android operating system [122326].
(b) The incident involving the Microsoft Teams bug blocking Android emergency calls has not been reported to have occurred at other organizations or with their products and services. It seems to be a specific issue related to the Microsoft Teams app on Android devices [122326]. |
| Phase (Design/Operation) |
design, operation |
(a) The software failure incident in the article can be attributed to the design phase. The bug that blocked Android users from making emergency calls was caused by an "unintended interaction" between the Microsoft Teams app and the Android operating system. This unintended interaction between the app and the operating system led to the issue where users were unable to make emergency calls, highlighting a failure introduced during the design or development phase of the software [122326].
(b) The software failure incident can also be linked to the operation phase. Users reported that the issue occurred when they were not logged into the Teams app. This suggests that the problem arose during the operation or use of the system, as it was dependent on the user's login status within the app. Additionally, the temporary fix suggested by Google involved either being signed in to the Teams app or uninstalling and reinstalling it, indicating that the operation or use of the app was a contributing factor to the failure [122326]. |
| Boundary (Internal/External) |
within_system |
(a) The software failure incident involving the Microsoft Teams app blocking Android emergency calls was primarily within the system. The issue was caused by an "unintended interaction" between the Teams app and the Android operating system [Article 122326]. The bug was specifically related to the behavior of the Microsoft Teams app when a user was not logged in, indicating an internal software issue within the app itself. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident in this case was due to a non-human action. The bug involving the Microsoft Teams app on Android devices causing the inability to make emergency calls was described as an "unintended interaction" between the Teams app and the Android operating system [Article 122326]. This unintended interaction led to the issue where the phone got stuck immediately after one ring when attempting to make an emergency call, highlighting a failure introduced without direct human participation. |
| Dimension (Hardware/Software) |
hardware, software |
(a) The software failure incident related to hardware:
- The incident was caused by an "unintended interaction" between the Microsoft Teams app and the Android operating system, indicating a contributing factor originating in the hardware [Article 122326].
(b) The software failure incident related to software:
- The bug that blocked Android users from making emergency calls was specifically related to an issue with the Microsoft Teams app, highlighting a contributing factor originating in the software itself [Article 122326]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident described in the article is non-malicious. The issue was caused by an "unintended interaction" between the Microsoft Teams app and the Android operating system, leading to a bug that prevented some Android users from making emergency calls [122326]. Both Google and Microsoft are actively working on a fix to address the problem, indicating that the failure was not due to malicious intent but rather an unintentional issue in the software. |
| Intent (Poor/Accidental Decisions) |
accidental_decisions |
(a) The software failure incident involving the Microsoft Teams bug that blocked Android emergency calls can be attributed to poor decisions. The incident was caused by an "unintended interaction" between the Teams app and the Android operating system, leading to the bug that prevented users from making emergency calls [Article 122326]. Additionally, some users speculated that the issue arose because Microsoft Teams, which can handle voice calls, may have attempted to handle the emergency call instead of allowing the default phone dialing app to manage it. This decision raised concerns among users about the reliability of the phone in critical situations [Article 122326]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident in Article 122326 was not explicitly attributed to development incompetence. The issue was described as an "unintended interaction" between the Microsoft Teams app and the Android operating system, leading to the bug that blocked Android users from making emergency calls. Google and Microsoft were actively working on a fix to address the problem, indicating a proactive response to the issue.
(b) The software failure incident in Article 122326 was categorized as accidental. The bug that prevented some Android users from making emergency calls was described as an "unusual bug" by Google. The incident was not intentional but rather an unexpected issue that arose from the interaction between the Teams app and the Android OS. Both Google and Microsoft acknowledged the seriousness of the problem, especially given that it impacted emergency calls, and were prioritizing a solution to resolve the issue promptly. |
| Duration |
temporary |
(a) The software failure incident in this case was temporary. The issue was caused by an "unintended interaction" between the Microsoft Teams app and the Android operating system, specifically affecting emergency calls on a small number of devices with the Teams app installed when the user is not logged in [Article 122326]. Google and Microsoft were actively working on a fix to address the bug, and in the meantime, users could temporarily resolve the problem by either being signed in to the Teams app or uninstalling and reinstalling it. |
| Behaviour |
crash, other |
(a) crash: The software failure incident in the article can be categorized as a crash. The bug involving the Microsoft Teams app caused some Android users to be unable to make emergency calls, with the phone getting stuck immediately after one ring, preventing the user from completing the call [Article 122326].
(b) omission: The incident does not directly involve omission as the system was not omitting to perform its intended functions but rather crashing and preventing users from making emergency calls [Article 122326].
(c) timing: The incident does not relate to timing issues where the system performs its intended functions but at the wrong time [Article 122326].
(d) value: The incident does not involve the system performing its intended functions incorrectly but rather failing to perform them at all due to the crash [Article 122326].
(e) byzantine: The incident does not exhibit byzantine behavior where the system behaves erroneously with inconsistent responses and interactions [Article 122326].
(f) other: The other behavior observed in this software failure incident is the unintended interaction between the Microsoft Teams app and the Android operating system, leading to the crash that blocked users from making emergency calls [Article 122326]. |
