Software Taxonomy of Faults

Category Option Rationale
Recurring unknown The articles do not provide information about the software failure incident happening again at either the same organization or at multiple organizations.
Phase (Design/Operation) design (a) The software failure incident reported in the articles seems to be related to the design phase. The incident was described as a major technical issue that caused delays in the programming schedule of BBC One. The delay was attributed to technical difficulties that occurred after the One Show finished, prompting the channel to put up an error message and struggle to get the Panorama episode on air, with several failed attempts including audio issues [107344]. (b) The software failure incident does not seem to be directly related to the operation phase or misuse of the system. The focus of the incident was on technical difficulties during the broadcast and delays in programming rather than issues caused by the operation or misuse of the system.
Boundary (Internal/External) within_system (a) within_system: The software failure incident reported in the article about BBC One going off-air was due to major technical issues within the system. The incident caused delays in the scheduled programming, including EastEnders starting 14 minutes later than planned. The channel experienced problems after The One Show finished, leading to an error message being displayed and the announcer trying to reassure viewers about the ongoing technical difficulties [Article 107344].
Nature (Human/Non-human) non-human_actions (a) The software failure incident in this case was primarily due to non-human actions. The incident was described as a result of 'major technical issues' that caused BBC One to go off-air for ten minutes, delaying the start of EastEnders [Article 107344]. The problems with the flagship channel led to a red screen being displayed to viewers with a message apologizing for the break in programming and indicating efforts to correct the fault. The technical difficulties also caused delays in other programs like Panorama, with the announcer acknowledging the issues and reassuring viewers that they were working on resolving them. Additionally, failed attempts were made to air the Panorama episode, including an instance where the audio failed on the program [Article 107344]. (b) While human actions may have played a role in addressing the issue and communicating with viewers, the root cause of the software failure incident was attributed to technical issues rather than human actions. The announcer, believed to be Delroy Haynes, provided updates and reassurances to viewers during the incident, but the primary focus was on resolving the technical difficulties that caused the disruption in programming [Article 107344].
Dimension (Hardware/Software) hardware (a) The software failure incident reported in Article 107344 was primarily due to hardware issues. The incident caused BBC One to be off-air for ten minutes, delaying the start of programs like Panorama and EastEnders. Viewers were greeted by a red screen and a statement apologizing for the break in the program, indicating a hardware-related problem. The announcer mentioned technical difficulties and reassured viewers that normal programming would resume as soon as possible, further suggesting hardware issues [107344].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident reported in the articles does not indicate any malicious intent behind the failure. It appears to be a non-malicious failure caused by technical issues and errors during the broadcast on BBC One [107344]. The incident was described as major technical issues that led to delays in the scheduled programming, including the start of Panorama and EastEnders. The announcer mentioned technical problems and reassured viewers that they were working on resolving them, indicating a non-malicious nature of the failure.
Intent (Poor/Accidental Decisions) unknown From the provided article, there is no specific information indicating whether the software failure incident related to the BBC One outage was due to poor decisions or accidental decisions. The incident seems to be primarily attributed to technical issues without clear details on the root cause being explicitly mentioned in the article.
Capability (Incompetence/Accidental) accidental (a) The software failure incident reported in the article seems to be more related to accidental factors rather than development incompetence. The incident was described as a result of 'major technical issues' that caused delays in the BBC One programming schedule, leading to the off-air situation and the need to display error messages to viewers. The announcer mentioned technical difficulties and reassured viewers that they were working on resolving the issues [Article 107344]. These aspects point more towards accidental factors causing the failure rather than development incompetence.
Duration temporary The software failure incident reported in Article 107344 was temporary. The BBC One channel experienced major technical issues that caused a 10-minute off-air period, delaying the start of programs like EastEnders and Panorama. The announcer reassured viewers that they were working on resolving the technical problems, indicating that the failure was not permanent but rather caused by specific circumstances [107344].
Behaviour crash, omission, other (a) crash: The software failure incident in the article resulted in a crash as BBC One was plunged off-air for ten minutes, causing major technical issues and delaying the start of programs like Panorama and EastEnders [Article 107344]. (b) omission: The software failure incident also involved omission as the system omitted to perform its intended functions at the instance when viewers were greeted by a red screen and a statement apologizing for the break in the program [Article 107344]. (c) timing: Timing was another aspect of the software failure incident as the delay caused the BBC One schedule to run five minutes late, impacting the timing of programs like Panorama and EastEnders [Article 107344]. (d) value: The software failure incident did not specifically mention the system performing its intended functions incorrectly, so this aspect is unknown based on the provided article. (e) byzantine: The software failure incident did not exhibit behaviors of inconsistent responses or interactions, so the byzantine behavior is unknown based on the provided article. (f) other: The other behavior observed in the software failure incident was the announcer trying to reassure viewers intermittently and updating them on the situation, indicating a form of communication or response management during the technical difficulties [Article 107344].
