Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident at Gatwick Airport due to an IT glitch involving Vodafone is a unique incident reported in the article [74457]. There is no mention of a similar incident happening before at Gatwick Airport or with Vodafone. (b) The article [74457] does not provide information about a similar incident happening at other organizations or with their products and services.
Phase (Design/Operation) design (a) The software failure incident at Gatwick Airport, where digital screens failed due to an IT glitch, can be attributed to a design-related issue. The problem was identified as an "ongoing issue with Vodafone," the airport's IT provider, indicating that the glitch was likely caused by factors introduced during system development, updates, or procedures to operate or maintain the system [74457].
Boundary (Internal/External) within_system (a) The software failure incident at Gatwick Airport, where digital screens failed due to an IT glitch, was attributed to an ongoing issue with Vodafone, the airport's IT provider [74457]. The problem was specifically mentioned to be related to a damaged fibre cable used by Gatwick Airport to display flight information, which was fixed by engineers [74457]. This indicates that the contributing factors leading to the software failure incident originated from within the system, specifically related to the infrastructure and components managed by the IT provider.
Nature (Human/Non-human) non-human_actions (a) The software failure incident at Gatwick Airport was attributed to an ongoing issue with Vodafone, the airport's IT provider. The problem was specifically identified as a damaged fibre cable used to display flight information, which was fixed by engineers [74457]. This indicates that the failure was due to non-human actions, specifically a technical issue with the infrastructure. (b) There is no specific mention in the article of the software failure incident being caused by human actions.
Dimension (Hardware/Software) hardware (a) The software failure incident at Gatwick Airport was attributed to a damaged fibre cable, which is a hardware issue. A Vodafone spokesperson mentioned that their engineers fixed the damaged fibre cable used by Gatwick Airport for displaying flight information [74457].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident at Gatwick Airport was non-malicious. The issue was attributed to an IT glitch caused by an ongoing problem with Vodafone, the airport's IT provider. The problem was specifically identified as a damaged fibre cable used to display flight information, which was fixed by engineers [74457].
Intent (Poor/Accidental Decisions) unknown The software failure incident at Gatwick Airport, where flight information screens failed due to an IT glitch, does not provide specific details to determine whether the incident was caused by poor decisions or accidental decisions. The article mentions that the issue was attributed to an ongoing problem with Vodafone, the IT provider, and was resolved by fixing a damaged fibre cable. There is no indication in the article that the failure was a result of poor decisions or accidental decisions.
Capability (Incompetence/Accidental) development_incompetence, accidental (a) The software failure incident at Gatwick Airport, where digital screens failed due to an IT glitch, can be attributed to development incompetence. The issue was identified as an "ongoing issue with Vodafone," the IT provider for the airport. The Vodafone spokesperson mentioned that engineers fixed a damaged fibre cable used for displaying flight information, indicating a technical fault that could have been prevented or resolved earlier with better professional competence [74457]. (b) The incident can also be categorized as accidental, as the Vodafone spokesperson mentioned that the problem was caused by a damaged fibre cable, which could have been an accidental physical damage leading to the software failure incident [74457].
Duration temporary (a) The software failure incident at Gatwick Airport, where the digital screens failed due to an IT glitch, was temporary. The issue was specifically attributed to an ongoing problem with Vodafone, the airport's IT provider. The problem was resolved by Monday evening after engineers fixed a damaged fibre cable used to display flight information [74457].
Behaviour crash, omission (a) crash: The software failure incident at Gatwick Airport resulted in the digital screens failing due to an IT glitch, leading to the need to post flight information on white boards. This can be categorized as a crash where the system lost its state and was unable to perform its intended function [74457]. (b) omission: While the incident caused inconvenience and led to a few people missing their flights, it did not result in flight delays, indicating that the system omitted to perform its intended functions at an instance(s) by not displaying the flight information as expected [74457]. (c) timing: There is no indication in the article that the system performed its intended functions too late or too early. The issue primarily revolved around the screens failing to display flight information, rather than a timing-related failure [74457]. (d) value: The software failure incident did not involve the system performing its intended functions incorrectly. Instead, the issue was with the system not displaying any information, leading to the need for manual intervention through white boards and announcements [74457]. (e) byzantine: The incident at Gatwick Airport did not exhibit characteristics of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. The failure was more straightforward, with the screens not functioning as expected due to an IT glitch [74457]. (f) other: The behavior of the software failure incident can be categorized as a crash due to the system losing its state and failing to display flight information on the digital screens, requiring alternative methods like white boards and announcements to convey the necessary information to passengers [74457].
