| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to the defective batteries at A123 Systems' Livonia, Mich., plant was caused by an incorrect calibration of one welding machine, leading to a misalignment of certain components in a battery cell. This misalignment resulted in a break in the electrical insulation and potential short circuit within the battery cells, ultimately causing the batteries to short out and prematurely fail [10641]. The CEO of A123 Systems, David Vieau, mentioned that the defect was isolated to a single automated welding machine at the Michigan plant, indicating an internal system issue within the manufacturing process.
(b) outside_system: The software failure incident was not attributed to factors originating from outside the system. The defect in the prismatic lithium-ion cells was identified as an internal issue within A123 Systems' manufacturing process at their Michigan plant, specifically linked to a misalignment caused by incorrect calibration of a welding machine [10641]. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident in this case was not related to non-human actions but rather to a defect in the manufacturing process of the batteries. The issue was traced back to an incorrect calibration of an automated welding machine at A123 Systems' Michigan plant, which caused a misalignment of components in the battery cells leading to a potential short circuit [10641].
(b) The software failure incident was a result of human actions, specifically the incorrect calibration of the welding machine at the manufacturing plant. The misalignment caused by this human error led to the defect in the battery cells, ultimately resulting in the premature failure of the batteries [10641]. |
| Dimension (Hardware/Software) |
hardware |
(a) The software failure incident in this case is related to hardware. The article mentions that the defect in A123 Systems' prismatic lithium ion cells, causing batteries to short out and prematurely fail, was due to an incorrect calibration of one welding machine at the Michigan plant. This misalignment of components in a battery cell led to a break in electrical insulation and potential short circuit, ultimately originating from a hardware issue [10641]. |

| Intent (Poor/Accidental Decisions) |
accidental_decisions |
The software failure incident described in the article does not directly relate to poor or accidental decisions. Instead, it is attributed to a defect in the manufacturing process of lithium-ion batteries at A123 Systems' plant in Michigan. The issue was traced back to an incorrect calibration of a welding machine, leading to misalignment of components in the battery cells, causing a potential short circuit [10641]. |
| Capability (Incompetence/Accidental) |
unknown |
Unknown |
| Duration |
temporary |
The software failure incident described in the article is not related to a temporary or permanent failure caused by software issues. Instead, it pertains to a defect in A123 Systems' prismatic lithium ion cells, specifically due to an incorrect calibration of a welding machine at the Michigan plant. This defect led to a misalignment of components in the battery cell, causing a break in electrical insulation and potential short circuits in the batteries [10641]. |
| Behaviour |
other |
(a) crash: The software failure incident in the article is not related to a crash where the system loses state and does not perform any of its intended functions. The failure is more related to a defect in the batteries causing them to short out and prematurely fail, leading to issues like the car not starting after being parked [Article 10641].
(b) omission: The software failure incident is not due to the system omitting to perform its intended functions at an instance(s). Instead, the issue is with a defect in the manufacturing process of the batteries that can cause them to fail prematurely [Article 10641].
(c) timing: The software failure incident is not due to the system performing its intended functions correctly but too late or too early. The issue is more related to a defect in the batteries that can lead to failures like the car not starting after being parked [Article 10641].
(d) value: The software failure incident is not due to the system performing its intended functions incorrectly. The issue is more related to a defect in the batteries causing them to short out and fail prematurely, affecting the starting of cars like the Fisker Karma [Article 10641].
(e) byzantine: The software failure incident is not related to the system behaving erroneously with inconsistent responses and interactions. The root cause of the issue was identified as a misalignment of components in the battery cells due to incorrect calibration of a welding machine, leading to potential shorts and failures [Article 10641].
(f) other: The behavior of the software failure incident in the article is more related to a manufacturing defect in the batteries that can cause them to short out and fail prematurely. The issue was traced back to a misalignment of components in the battery cells due to an incorrect calibration of a welding machine, rather than a specific software-related behavior [Article 10641]. |
