Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to delayed or unavailable rearview image displays has happened again at Tesla Inc. The article mentions that this recall is the latest in a series of recalls Tesla has conducted for software issues in recent months. Additionally, it states that Tesla began deploying firmware to a limited number of vehicles, which led to an abnormal frequency of computer resets among Model 3 vehicles, ultimately leading to an engineering investigation that identified a software error as a potential cause for further assessment [125569]. (b) The software failure incident related to delayed or unavailable rearview image displays has not been explicitly mentioned to have happened at other organizations in the provided article. Therefore, there is no information available regarding similar incidents at multiple organizations.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase is evident in the article. Tesla is recalling 947 vehicles in the United States because the rearview image may not immediately display when they begin to reverse. This issue is attributed to a software error identified during an engineering investigation into the condition, which was potentially caused by a software error introduced during the development or update of the firmware deployed to the vehicles [125569]. (b) The software failure incident related to the operation phase is also highlighted in the article. The delayed rearview camera image, which increases the risk of a crash, is a result of the operation or use of the vehicles equipped with Autopilot Computer 2.5 and certain firmware releases. The issue was identified through consumer complaints about delayed or unavailable rearview image displays during the operation of the vehicles [125569].
Boundary (Internal/External) within_system (a) The software failure incident in the Tesla vehicles is within_system. The article mentions that Tesla identified a software error as a potential cause for further assessment after an engineering investigation into the condition [125569]. This indicates that the failure originated from within the system itself.
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case was primarily due to non-human actions. The article mentions that Tesla is recalling vehicles because the rearview image may not immediately display when they begin to reverse, which is a result of a software error identified during an engineering investigation into the condition [125569]. This indicates that the failure was introduced through software and not directly due to human actions.
Dimension (Hardware/Software) hardware, software (a) The software failure incident in the article is related to hardware. Tesla is recalling vehicles because the rearview image may not immediately display when they begin to reverse, which is caused by a software error in the Autopilot Computer 2.5 and certain firmware releases [125569].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident described in Article 125569 is categorized as non-malicious. The failure was due to a software error identified by an engineering investigation as a potential cause for further assessment. Despite not finding a noncompliance in the tests conducted by Tesla, a recall determination was made out of an abundance of caution to recognize the potential presence of a noncompliance in affected vehicles [125569].
Intent (Poor/Accidental Decisions) unknown (a) The software failure incident related to the Tesla recall was not explicitly attributed to poor decisions but rather to a software error identified during an engineering investigation into the condition [125569]. The recall was initiated out of an abundance of caution despite not finding a noncompliance in the tests conducted by Tesla. This indicates that the failure was not due to poor decisions but rather a precautionary measure taken to address potential software issues.
Capability (Incompetence/Accidental) accidental (a) The software failure incident in the Tesla vehicles was not attributed to development incompetence. The article mentions that the issue was identified as a software error during an engineering investigation, and despite not finding a noncompliance in the tests conducted by Tesla, a recall was initiated out of caution [125569]. (b) The software failure incident in the Tesla vehicles was more aligned with an accidental failure. The article highlights that the delayed rearview camera image issue was identified after deploying firmware to a limited number of vehicles, and an abnormal frequency of computer resets was observed, leading to an engineering investigation that identified a software error as a potential cause [125569].
Duration temporary The software failure incident reported in Article 125569 regarding Tesla's recall of 947 vehicles in the United States due to a rearview image display issue can be categorized as a temporary failure. The article mentions that Tesla identified a software error as a potential cause for further assessment after an engineering investigation into the condition [125569]. Additionally, despite not finding a noncompliance in the tests conducted by Tesla, a recall determination was made out of an abundance of caution to recognize the potential presence of a noncompliance in affected vehicles [125569]. These details indicate that the software failure incident was temporary and not a permanent issue.
Behaviour value (a) crash: The software failure incident in the article is not described as a crash where the system loses state and does not perform any of its intended functions [125569]. (b) omission: The software failure incident in the article is not described as an omission where the system omits to perform its intended functions at an instance(s) [125569]. (c) timing: The software failure incident in the article is not described as a timing issue where the system performs its intended functions correctly, but too late or too early [125569]. (d) value: The software failure incident in the article is described as a value issue where the system performs its intended functions incorrectly. Specifically, the rearview image may not immediately display when the vehicles begin to reverse, which increases the risk of a crash [125569]. (e) byzantine: The software failure incident in the article is not described as a byzantine failure where the system behaves erroneously with inconsistent responses and interactions [125569]. (f) other: The software failure incident in the article is not described as any other specific behavior beyond the value issue mentioned above [125569].
