Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident having happened again at one_organization: - Tesla has faced claims of brake failure in China before, with a Chinese car owner being ordered by a court to publicly apologize and compensate the firm after making comments about brake issues inconsistent with the facts [134997]. - Last year, a customer protested at the Shanghai auto show about malfunctioning brakes involved in a car accident, with Tesla attributing the crash to speeding violations but promising to improve how it addressed customer complaints [134997]. (b) The software failure incident having happened again at multiple_organization: - There is no specific mention in the provided article about similar incidents happening at other organizations or with their products and services.
Phase (Design/Operation) design, operation (a) The software failure incident in the Tesla crash in China could potentially be related to the design phase. Tesla mentioned that their data showed the car's brake pedal was never engaged while it was speeding through town, indicating a possible issue with the system design or automatic features of the vehicle [134997]. (b) The software failure incident could also be related to the operation phase. The family of the driver mentioned that the 55-year-old man lost control of the car and that it would not respond when he stepped on the brake pedal, suggesting a failure related to the operation or use of the vehicle [134997].
Boundary (Internal/External) within_system, outside_system (a) within_system: The software failure incident involving the Tesla Model Y speeding through the streets of a Chinese province and causing fatalities and injuries seems to have elements of a within_system failure. Tesla mentioned that their data showed issues such as there being no action to step on the brakes throughout the vehicle's journey, indicating a potential internal system failure related to the car's braking system [134997]. (b) outside_system: On the other hand, there are indications of potential contributing factors originating from outside the system as well. The family of the driver mentioned that the 55-year-old man lost control of the car and that it would not respond when he stepped on the brake pedal, suggesting a possible external factor affecting the car's response [134997]. Additionally, the incident took place in a real-world environment with interactions with other vehicles and pedestrians, which could have introduced external factors contributing to the failure.
Nature (Human/Non-human) non-human_actions, human_actions (a) The software failure incident occurring due to non-human actions: - The incident involving the out-of-control Tesla speeding through the streets of a Chinese province, killing two and injuring three, was attributed to potential issues with the car's automatic features [134997]. - Tesla mentioned that their data showed the car's brake pedal was never engaged while it was speeding through town, indicating a potential malfunction in the automatic braking system [134997]. (b) The software failure incident occurring due to human actions: - The family of the driver involved in the incident stated that the 55-year-old man lost control of the car and that it would not respond when he stepped on the brake pedal, suggesting a potential human error or misjudgment in handling the vehicle [134997]. - There were claims of brake failure in China related to Tesla vehicles in the past, including instances where customers raised complaints about malfunctioning brakes [134997].
Dimension (Hardware/Software) hardware, software (a) The software failure incident occurring due to hardware: - The incident involving the out-of-control Tesla speeding through the streets of a Chinese province, resulting in two deaths and three injuries, was initially reported to have occurred due to the driver losing control of the car and the vehicle not responding when the brake pedal was pressed [134997]. - Tesla mentioned that their data showed the car's brake pedal was never engaged while the car was speeding through town, indicating a potential hardware issue with the brake system [134997]. (b) The software failure incident occurring due to software: - The incident highlighted potential issues with Tesla's automatic features being fingered as potential culprits in the wreck [134997]. - Tesla stated that videos showed the car's brake lights were not on when the car was speeding, and their data indicated there was no action to step on the brakes throughout the vehicle's journey, suggesting a software-related anomaly [134997].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident in the news articles does not indicate any malicious intent or actions by humans to harm the system. The incident seems to be related to potential non-malicious factors such as a malfunction in the car's brake system or automatic features [134997]. The family of the driver mentioned issues with the brake pedal, and Tesla's data showed that the car's brake pedal was never engaged while it was speeding through town. Tesla cautioned against rumors and stated they were working with local authorities to identify the truth of what led to the accident. Additionally, Tesla mentioned that a Chinese car owner had been ordered by a court to publicly apologize and compensate the firm after comments he made about issues with his brakes were ruled inconsistent with the facts [134997].
Intent (Poor/Accidental Decisions) unknown The articles do not provide specific information about the intent of the software failure incident in terms of whether it was due to poor decisions or accidental decisions. Therefore, it is unknown from the provided articles.
Capability (Incompetence/Accidental) accidental (a) The software failure incident in the Tesla crash in China does not seem to be directly related to development incompetence. The incident was primarily focused on the car's brake system not engaging properly, leading to the out-of-control situation. Tesla mentioned that their data showed issues such as there being no action to step on the brakes throughout the vehicle's journey, indicating a potential technical malfunction rather than a development incompetence issue [134997]. (b) The software failure incident in the Tesla crash in China appears to be more related to accidental factors. The incident involved the car's brake system not engaging properly, leading to the car speeding uncontrollably through the streets and causing a fatal crash. Tesla mentioned that their data showed issues such as there being no action to step on the brakes throughout the vehicle's journey, indicating a potential technical malfunction that occurred accidentally rather than intentionally [134997].
Duration unknown The articles do not provide specific information about the duration of the software failure incident related to the Tesla incident in China. Therefore, it is unknown whether the software failure incident was permanent or temporary.
Behaviour crash, omission (a) crash: The software failure incident in the article can be categorized as a crash. The Tesla vehicle lost control, sped through the streets, and ultimately crashed into a building, resulting in fatalities and injuries [134997]. (b) omission: The incident involved a failure of the system to respond when the driver stepped on the brake pedal. Tesla's data showed that the car's brake pedal was never engaged while it was speeding through town, indicating an omission of the intended function [134997]. (c) timing: There is no specific information in the articles to suggest that the software failure incident was related to timing issues. (d) value: The software failure incident did not involve the system performing its intended functions incorrectly. (e) byzantine: The incident did not exhibit characteristics of a byzantine failure where the system behaves erroneously with inconsistent responses and interactions. (f) other: The behavior of the software failure incident could be described as a combination of a crash (loss of control leading to the vehicle speeding and crashing) and an omission (failure to respond to the driver's actions on the brake pedal).
