Postmortem Analysis
Timeline 1. The software failure incident mentioned in the article did not have a specific date or timeline associated with it. 2. Therefore, the timeline of the software failure incident is unknown.
System Unknown
Responsible Organization unknown
Impacted Organization unknown
Software Causes unknown
Non-software Causes 1. Extreme weather conditions with temperatures as low as -24 degrees Celsius [Article 55551] 2. Repetitive wind events triggered by the topography of Dead Mountain [Article 55551] 3. Infrasound waves produced by high winds resonating due to the shape of the mountains [Article 55551]

Software Taxonomy of Faults

Category Option Rationale
Recurring unknown unknown
Phase (Design/Operation) design unknown
Boundary (Internal/External) unknown The articles do not contain information about a software failure incident, so the boundary of the software failure incident related to within_system or outside_system cannot be determined from the provided articles.
Nature (Human/Non-human) unknown unknown
Dimension (Hardware/Software) unknown Unknown
Objective (Malicious/Non-malicious) unknown unknown
Intent (Poor/Accidental Decisions) unknown unknown
Capability (Incompetence/Accidental) unknown Unknown
Duration unknown Unknown
Behaviour other (a) crash: The software failure incident described in the articles does not involve a crash where the system loses state and does not perform any of its intended functions. The incident discussed is related to the mysterious deaths of nine skiers in the Siberian wilderness in 1959, with a proposed explanation involving infrasound affecting the behavior of the skiers [Article 55551]. (b) omission: The software failure incident does not involve a failure due to the system omitting to perform its intended functions at an instance(s). The incident is focused on the deaths of the skiers and the potential influence of infrasound on their behavior [Article 55551]. (c) timing: The software failure incident is not related to a failure due to the system performing its intended functions correctly but too late or too early. The focus of the incident is on the behavior of the skiers and the potential impact of infrasound on their actions [Article 55551]. (d) value: The software failure incident is not characterized by a failure due to the system performing its intended functions incorrectly. The incident discussed in the articles is about the mysterious deaths of the skiers and the potential role of infrasound in influencing their behavior [Article 55551]. (e) byzantine: The software failure incident does not exhibit a byzantine behavior where the system behaves erroneously with inconsistent responses and interactions. The incident described pertains to the Dyatlov Pass incident and the potential explanation involving infrasound affecting the skiers' actions [Article 55551]. (f) other: The software failure incident does not fit into the categories of crash, omission, timing, value, or byzantine behaviors. The incident is unique in nature, focusing on the mysterious circumstances surrounding the deaths of the skiers and the proposed scientific explanation involving infrasound [Article 55551].
