Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The articles do not mention any software failure incidents related to either one_organization or multiple_organization. Therefore, the information about the software failure incidents happening again at the same organization or at multiple organizations is unknown.
Phase (Design/Operation) design Unknown
Boundary (Internal/External) within_system (a) within_system: The software failure incident related to the engine fire recall for Hyundai vehicles is primarily within the system. The issue was identified as improperly heat-treated piston oil rings, which could lead to a fire occurring in the engine compartment. This defect originates from within the system of the vehicles, specifically related to the manufacturing process of the piston oil rings [115010].
Nature (Human/Non-human) unknown (a) The articles do not mention any software failure incident related to non-human actions or factors introduced without human participation. (b) The articles do not mention any software failure incident related to human actions or factors introduced by human actions.
Dimension (Hardware/Software) unknown (a) The article does not mention any software failure incident related to hardware contributing factors originating in hardware. (b) The article does not mention any software failure incident related to software contributing factors originating in software.
Objective (Malicious/Non-malicious) unknown Unknown
Intent (Poor/Accidental Decisions) unknown Unknown
Capability (Incompetence/Accidental) unknown Unknown
Duration unknown The articles do not mention any software failure incident related to the Hyundai and Kia vehicle recalls. Therefore, the duration of the software failure incident is unknown.
Behaviour unknown (a) crash: The articles do not mention any software failure incident related to a crash where the system loses state and does not perform any of its intended functions [115010]. (b) omission: The articles do not mention any software failure incident related to omission where the system omits to perform its intended functions at an instance(s) [115010]. (c) timing: The articles do not mention any software failure incident related to timing where the system performs its intended functions correctly, but too late or too early [115010]. (d) value: The articles do not mention any software failure incident related to value where the system performs its intended functions incorrectly [115010]. (e) byzantine: The articles do not mention any software failure incident related to a byzantine failure where the system behaves erroneously with inconsistent responses and interactions [115010]. (f) other: The articles do not mention any other specific behavior of a software failure incident not covered by the options provided [115010].
