Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to Volkswagen's newest Golf model involved data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. Volkswagen had to halt sales and develop a software update to address the issue, affecting both future models and the 15,000 vehicles already sold [101643]. This incident indicates a software failure within the same organization, Volkswagen, with its product. (b) There is no information in the provided article about a similar incident happening at other organizations or with their products and services.
Phase (Design/Operation) design (a) The software failure incident in the Volkswagen case was related to the design phase. The article mentions that Volkswagen discovered data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. This issue was identified in the system design, leading to the voluntary halt in sales and the development of a software update for the control unit of the online connectivity unit to remedy the situation [101643].
Boundary (Internal/External) within_system (a) The software failure incident reported in Article 101643 was within_system. Volkswagen discovered that data transfer problems in an online connectivity unit within the Golf model could interfere with an emergency assist functionality. The company developed a software update for the control unit of the online connectivity unit to address this issue, indicating that the failure originated from within the system itself [101643].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in the Volkswagen Golf model was due to non-human actions. Specifically, it was caused by data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. Volkswagen developed a software update to address this issue, indicating that the failure was not directly caused by human actions [101643].
Dimension (Hardware/Software) hardware (a) The software failure incident in the article was related to hardware. Volkswagen halted sales of its newest Golf model due to data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. The issue was addressed by developing a software update for the control unit of the online connectivity unit, indicating that the root cause of the failure originated in the hardware component [101643].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident reported in Article 101643 was non-malicious. Volkswagen voluntarily halted sales of its newest Golf model after discovering data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. The company developed a software update to address the issue and resumed deliveries of the affected vehicles. There is no indication in the article that the failure was due to malicious intent; rather, it was a technical issue that needed to be fixed to ensure the proper functioning of the vehicles [101643].
Intent (Poor/Accidental Decisions) poor_decisions (a) The software failure incident related to Volkswagen's newest Golf model was due to data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. Volkswagen voluntarily halted sales and developed a software update to address the issue. This incident could be attributed to poor decisions in the design or implementation of the online connectivity unit software [101643].
Capability (Incompetence/Accidental) accidental (a) The software failure incident in the Volkswagen Golf model was not explicitly attributed to development incompetence. Instead, it was mentioned that the issue arose from data transfer problems in an online connectivity unit that could interfere with emergency assist functionality. Volkswagen addressed the problem by developing a software update for the control unit of the online connectivity unit [Article 101643]. (b) The software failure incident in the Volkswagen Golf model was described as an issue related to data transfer problems in an online connectivity unit that could interfere with emergency assist functionality. This indicates that the failure was accidental rather than intentional [Article 101643].
Duration temporary The software failure incident reported in Article 101643 was temporary. Volkswagen voluntarily halted sales of its newest Golf model in mid-May due to data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality. The company developed a software update to address the issue, which will be installed on future Golf 8 models as standard and also on the 15,000 vehicles affected by the recall. This indicates that the failure was temporary and could be resolved through a software update [101643].
Behaviour value, other (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 [101643]. (b) omission: The software failure incident is not described as an omission where the system omits to perform its intended functions at an instance(s) [101643]. (c) timing: The software failure incident is not described as a timing issue where the system performs its intended functions correctly, but too late or too early [101643]. (d) value: The software failure incident is described as a value issue where the system performs its intended functions incorrectly. In this case, data transfer problems in an online connectivity unit could interfere with an emergency assist functionality, leading to the recall of 15,000 vehicles and the development of a software update to address the issue [101643]. (e) byzantine: The software failure incident is not described as a byzantine failure where the system behaves erroneously with inconsistent responses and interactions [101643]. (f) other: The software failure incident in the article is specifically related to data transfer problems in an online connectivity unit that could interfere with an emergency assist functionality, leading to the need for a software update and a temporary halt in sales of the Golf model by Volkswagen [101643].
