Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization, multiple_organization (a) The software failure incident having happened again at one_organization: The article mentions various quality control problems faced by Tesla, including electrical gremlins, poor panel alignment, rattles, and other issues reported by Tesla owners [59545]. These issues indicate recurring software and manufacturing problems within the organization. (b) The software failure incident having happened again at multiple_organization: The article discusses how Tesla's quality control problems pose a significant challenge as the company transitions to mass manufacturing, indicating that other automakers also face similar issues with recalls and complaints [59545]. This suggests that software failure incidents are not unique to Tesla but are common across the automotive industry.
Phase (Design/Operation) design, operation (a) The article mentions quality control problems at Tesla as the company transitions from a boutique automaker to mass manufacturer, gearing up to build the $35,000 Model 3 sedan. Issues such as electrical gremlins, poor panel alignment, rattles, and other problems have been reported by Tesla owners, indicating failures in the design phase of the software or system development [59545]. (b) The article also discusses complaints and issues reported by Tesla owners, such as a cracked windshield pillar, unexpected shutdowns, and a lawsuit alleging the Autopilot feature is unsafe. These issues could be attributed to failures in the operation phase, where factors introduced by the operation or misuse of the system contribute to the software failure incidents [59545].
Boundary (Internal/External) within_system (a) within_system: The software failure incident reported in the articles is primarily related to issues within the system. The articles mention various quality control problems faced by Tesla, such as electrical gremlins, poor panel alignment, rattles, cracked windshield pillar, unexpected shutdowns, and issues with the Autopilot feature. These issues point towards internal factors within Tesla's manufacturing and software systems leading to the reported failures [59545].
Nature (Human/Non-human) human_actions (a) The software failure incident occurring due to non-human actions: The articles do not specifically mention any software failure incident occurring due to non-human actions. (b) The software failure incident occurring due to human actions: The articles mention various quality control problems and complaints reported by Tesla owners, such as electrical gremlins, poor panel alignment, rattles, and other issues [59545]. These issues are likely a result of human actions during the manufacturing or design process. Additionally, the article discusses how Tesla is working to address problems reported by customers, indicating that human actions play a role in resolving software failure incidents as well.
Dimension (Hardware/Software) unknown (a) The articles do not specifically mention a software failure incident occurring due to hardware issues.
