Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident of Xbox Series X controllers disconnecting and reconnecting has happened again within the same organization, Microsoft. The issue with the controllers was reported earlier by The Verge and has led to hundreds of complaints on Microsoft's Xbox forum [110581]. The problem has affected both the blue and black versions of the controllers and has been ongoing since mid-November when the console was released. Customers have been experiencing frequent disconnects, with some stating that the only solution is to repair the controllers, and others mentioning that the controllers only work when plugged in. Microsoft has acknowledged the issue and is actively working on a solution to be included in a future update.
Phase (Design/Operation) design (a) The software failure incident in the article is related to the design phase. Microsoft acknowledged an issue with some Xbox Series X controllers where they continually disconnect and reconnect. The problem was reported to occur across both the blue and black versions of the controllers, with complaints starting in mid-November when the console was released. Microsoft mentioned actively working on a solution to be included in a future update, indicating that the issue was introduced during the development or design phase of the controllers [110581]. (b) The software failure incident is not related to the operation phase or misuse of the system. The reported issue with the Xbox Series X controllers was not caused by the operation or misuse of the controllers but rather by a design flaw that led to the disconnect and reconnect problem. Users complained about the controllers not staying connected even when plugged in, indicating a technical issue rather than misuse [110581].
Boundary (Internal/External) within_system (a) within_system: The software failure incident with the Xbox Series X controllers disconnecting and reconnecting is reported to be due to an issue within the system itself. Microsoft is actively working on a solution to be included in a future update to fix the problem [110581]. The complaints about the controllers' disconnects are originating from users who are experiencing the issue with both the blue and black versions of the controllers, indicating an internal system issue rather than an external factor.
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case seems to be related to non-human actions. The issue causing some Xbox Series X controllers to continually disconnect and reconnect is attributed to a fault in the controllers themselves, as mentioned by Microsoft. The company is actively working on a solution to be included in a future update to correct this issue [110581].
Dimension (Hardware/Software) hardware (a) The software failure incident reported in Article 110581 is related to hardware. Microsoft acknowledged an issue causing some Xbox Series X controllers to continually disconnect and reconnect. The problem was reported across both the blue and black versions of the controllers, with complaints from users about frequent disconnects and the need to constantly repair or plug in the controllers [110581].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in the article is non-malicious. Microsoft acknowledged the issue with some Xbox Series X controllers disconnecting and reconnecting, and they are actively working on a solution to be included in a future update. The problem seems to be related to a firmware issue in the controllers, as Microsoft is recommending customers to update to the latest controller firmware to address the disconnects. The complaints on Microsoft's Xbox forum indicate that users are facing issues with the controllers, such as frequent disconnections and the controllers only working when plugged in. There is no indication in the article that the failure was caused by malicious intent; rather, it appears to be a technical issue that Microsoft is addressing ([110581]).
Intent (Poor/Accidental Decisions) accidental_decisions (a) The software failure incident related to the Xbox Series X controllers disconnecting and reconnecting does not seem to be directly linked to poor decisions. Instead, it appears to be a technical issue with the controllers themselves that Microsoft is actively working to address through a firmware update [110581]. (b) The incident seems to be more aligned with accidental decisions or unintended consequences rather than poor decisions. Users are experiencing issues with the controllers disconnecting and reconnecting, which is causing frustration and inconvenience. Microsoft is responding to these complaints and working on a solution to be included in a future update, indicating that the problem was not intentionally introduced but rather an unintended issue that arose after the console's release [110581].
Capability (Incompetence/Accidental) accidental (a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article. (b) The software failure incident related to accidental factors is evident in the article. The issue causing some Xbox Series X controllers to continually disconnect and reconnect was reported to occur across both the blue and black versions of the controllers. This issue was not intentional but rather an accidental flaw that affected numerous customers, leading to complaints and the need for a future update to address the problem [110581].
Duration temporary The software failure incident related to Xbox Series X controllers disconnecting and reconnecting is temporary. This is evident from the fact that Microsoft is actively working on a solution to be included in a future update for the faulty controllers [110581]. Additionally, users have reported that the controllers work only when plugged in, indicating a temporary issue that can potentially be resolved with a software update.
Behaviour value, other (a) crash: The software failure incident described in the article is not related to a crash where the system loses state and does not perform any of its intended functions. The issue with the Xbox Series X controllers is about disconnecting and reconnecting rather than a complete system crash [110581]. (b) omission: The software failure incident is not related to omission where the system omits to perform its intended functions at an instance(s). The issue with the controllers is about disconnecting and reconnecting, not about the system omitting functions [110581]. (c) timing: The software failure incident is not related to timing where the system performs its intended functions correctly but too late or too early. The issue with the controllers is about disconnecting and reconnecting, not about timing problems [110581]. (d) value: The software failure incident is related to the value where the system performs its intended functions incorrectly. In this case, the Xbox Series X controllers are disconnecting and reconnecting, causing inconvenience to users and requiring frequent repairs [110581]. (e) byzantine: The software failure incident is not related to a byzantine behavior where the system behaves erroneously with inconsistent responses and interactions. The issue with the controllers is consistent in terms of disconnecting and reconnecting [110581]. (f) other: The behavior of the software failure incident is related to intermittent disconnection and reconnection of the Xbox Series X controllers, leading to a situation where the controllers do not stay connected for more than a few seconds. Users are experiencing frequent disconnects, requiring them to unplug and repair the controllers often [110581].
