Software Taxonomy of Faults

Category Option Rationale
Recurring unknown (a) The software failure incident having happened again at one_organization: The article does not mention any specific incident of software failure happening again within the same organization or with its products and services. Therefore, there is no information available to indicate a repeated software failure incident within the same organization. (b) The software failure incident having happened again at multiple_organization: The article does not provide information about similar incidents of software failure happening at other organizations or with their products and services. Hence, there is no mention of a repeated software failure incident across multiple organizations in the articles provided.
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase: The article mentions that the German Navy's latest warship, the Baden-Württemberg, has faced delays and technology challenges, particularly with its central computer system not passing necessary tests. The ship had to return to port to resolve unspecified technology issues related to the IT infrastructure [66978]. (b) The software failure incident related to the operation phase: The article discusses that troubleshooting the IT problems on the ship can be a tough task, as all software and hardware faults of the IT systems used on the ship must be eliminated for acceptance trials to be carried out. The spokesman mentioned that defects are often found at interfaces between subsystems, making their analysis more difficult [66978].
Boundary (Internal/External) within_system (a) The software failure incident related to the German Navy's Baden-Württemberg warship appears to be primarily within_system. The articles mention that the ship's central computer system faced technology challenges and had not passed necessary tests, leading to delays in trials and operability issues [66978]. The spokesman for Thyssenkrupp, the company leading the consortium building the ships, mentioned that necessary revisions caused delays in proving the ship's operability, indicating internal software issues [66978]. Additionally, troubleshooting activities were planned to be carried out by the consortium to address IT problems within the ship's systems [66978]. (b) The software failure incident does not seem to have significant contributing factors originating from outside the system. The reported issues, such as problems with radar, electronics, flameproof coating, and the ship listing slightly to its starboard side, were mentioned as internal challenges being resolved by the ARGE F125 consortium [66978]. The criticism about the ship lacking necessary weaponry for anti-submarine warfare also pertains to internal design decisions rather than external factors impacting the software failure incident.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: The software failure incident related to the German Navy's Baden-Württemberg warship was primarily attributed to technology challenges and issues with the ship's central computer system during sea trials. The ship's IT infrastructure faced problems that needed to be resolved, leading to delays in the trials to prove its operability [66978]. (b) The software failure incident occurring due to human actions: The delays and technology challenges faced by the Baden-Württemberg warship were also influenced by human actions, such as necessary revisions and troubleshooting activities carried out by the ARGE F125 consortium and the Federal Office of Bundeswehr Equipment, Information Technology, and In-Service Support (BAAINBw). The integration of various systems and fulfilling increased reliability requirements associated with intensive use posed significant challenges for the manufacturers and project participants [66978].

Domain government (a) The failed system was intended to support the defense industry. The software failure incident was related to the delays and technology challenges faced by the German Navy's new F-125 class frigate, the Baden-Württemberg. The ship's central computer system had not passed necessary tests, leading to delays in trials and the need for troubleshooting activities [66978]. The frigate is a technically sophisticated vessel with new technologies, and the software and hardware faults of the IT systems used on the ship needed to be eliminated for the acceptance trials to be carried out [66978]. (l) The failed system was also related to the government industry. The F-125 class frigate, Baden-Württemberg, is part of the German military's fleet and is being built for the Bundeswehr, the German military, with a total price tag of around €2 billion [66978]. The ship is expected to be handed over to the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw) [66978]. The German military's involvement in the project and the need for the ship to meet military standards indicate the government industry's connection to this software failure incident.
