Software Taxonomy of Faults

Category Option Rationale
Recurring one_organization (a) The software failure incident related to the overheating issue affecting first-generation iPod Nanos has happened again at Apple. In 2008, Apple issued a recall for first-generation Nanos in Japan for the exact same reasons, citing battery overheating problems traced back to a single supplier that delivered batteries with a manufacturing defect. This recurrence of the issue within the same organization suggests a persistent problem with the batteries in these devices [9076]. (b) The software failure incident related to the battery overheating issue in first-generation iPod Nanos has not been reported to have occurred at other organizations or with their products and services. The articles specifically mention Apple's recall in 2008 and the recent recall, indicating that this issue has been isolated to Apple's first-generation iPod Nano devices [9076].
Phase (Design/Operation) design, operation (a) The software failure incident related to the design phase is evident in the articles. The issue with the first generation iPod Nano MP3 players overheating was traced back to a manufacturing defect in the batteries supplied by a single supplier. This defect in the design of the batteries led to the overheating problem, causing failure and deformation of the iPod Nano [9076]. (b) The software failure incident related to the operation phase is also highlighted in the articles. Apple recommended that owners of the affected iPod Nanos stop using the units to prevent any safety risks posed by the overheating batteries. This recommendation indicates that the failure was due to factors introduced by the operation or misuse of the devices [9076].
Boundary (Internal/External) within_system (a) within_system: The software failure incident of the battery overheating issue in the first generation iPod Nano was attributed to a manufacturing defect in the batteries supplied by a single supplier. This defect originated from within the system, specifically from the manufacturing process of the batteries used in the iPod Nano devices [9076].
Nature (Human/Non-human) non-human_actions (a) The software failure incident related to non-human actions in this case is the overheating issue affecting some first-generation iPod Nano MP3 players. This issue was traced back to a manufacturing defect in the batteries supplied by a single supplier, leading to the batteries aging poorly and potentially overheating, causing failure and deformation of the iPod Nano [9076].
Dimension (Hardware/Software) hardware (a) The software failure incident in the article is related to hardware. The issue with the first generation iPod Nano MP3 players was caused by a battery overheating problem, which poses a safety risk. This hardware issue was traced back to a single supplier that delivered batteries with a manufacturing defect [9076].
Objective (Malicious/Non-malicious) non-malicious (a) The software failure incident related to the overheating issue in first-generation iPod Nano MP3 players was non-malicious. The failure was attributed to a manufacturing defect in the batteries supplied by a single supplier, leading to overheating and posing a safety risk to users. This issue was not caused by any malicious intent but rather by a flaw in the manufacturing process [9076].
Intent (Poor/Accidental Decisions) unknown The software failure incident related to the iPod Nano recall was not directly caused by poor or accidental decisions related to software. The issue was traced back to a manufacturing defect in the batteries supplied by a single supplier, leading to overheating problems in the affected iPod Nanos [9076].
Capability (Incompetence/Accidental) accidental (a) The articles do not mention any software failure incident related to development incompetence. (b) The software failure incident related to accidental factors is the overheating issue affecting some first-generation iPod Nano MP3 players. This issue was traced back to a single supplier that delivered batteries with a manufacturing defect, leading to the batteries overheating and posing a safety risk [9076].
Duration temporary The software failure incident related to the overheating issue affecting first-generation iPod Nano MP3 players can be considered as a temporary failure. The articles mention that the battery overheating problem was traced to a single supplier that delivered batteries with a manufacturing defect. This indicates that the failure was due to specific circumstances related to the manufacturing defect in the batteries, rather than a permanent issue affecting all units. The incident was not a universal problem but rather specific to the affected units sold between September 2005 and December 2006 [9076].
Behaviour other (a) crash: The software failure incident in the article does not involve a crash where the system loses state and does not perform any of its intended functions. The issue mentioned is related to a battery overheating problem in first-generation iPod Nanos, leading to a safety risk and potential failure of the device [9076]. (b) omission: The software failure incident does not involve omission where the system omits to perform its intended functions at an instance(s). The issue is specifically related to a battery overheating problem in the iPod Nano devices, leading to a safety risk and potential device failure [9076]. (c) timing: The software failure incident does not involve timing issues where the system performs its intended functions correctly but too late or too early. The issue discussed in the article is related to a battery overheating problem in first-generation iPod Nanos, potentially causing device failure [9076]. (d) value: The software failure incident does not involve a value issue where the system performs its intended functions incorrectly. The main problem highlighted in the article is the battery overheating in first-generation iPod Nanos, leading to safety concerns and potential device failure [9076]. (e) byzantine: The software failure incident does not exhibit a byzantine behavior where the system behaves erroneously with inconsistent responses and interactions. The issue discussed in the article is related to a specific hardware problem (battery overheating) in the iPod Nano devices, leading to safety risks and potential device failure [9076]. (f) other: The software failure incident in the article is primarily related to a hardware issue (battery overheating) in first-generation iPod Nanos, leading to a safety risk and potential device failure. The failure is not directly attributed to software issues but rather to a manufacturing defect in the batteries supplied for the devices [9076].
