| Postmortem Analysis | |
|---|---|
| Timeline | 1. The software failure incident involving the exploding oven door at IKEA happened less than a year before the article was published on July 16, 2019 [Article 87891]. Therefore, the estimated timeline for the software failure incident would be around July 2018. |
| System | unknown |
| Responsible Organization | unknown |
| Impacted Organization | 1. Customers who purchased the IKEA Mattradition forced-air ovens made by Whirlpool were impacted by the software failure incident as the tempered glass used in the oven doors had a tendency to explode, causing potential safety hazards [87891]. |
| Software Causes | unknown |
| Non-software Causes | 1. The tempered glass used in the IKEA oven door had a tendency to explode due to the way it was manufactured and its brittleness [87891]. |
| Impacts | 1. The oven door of the IKEA Mattradition forced-air oven, made by Whirlpool, exploded, sending hot glass shards all over the kitchen floor, scorching the recently-installed flooring, which cost £600 to install [87891]. 2. The incident caused damage to the new vinyl floor, leading the affected individual to go through the insurance process to get it fixed, causing hassle and inconvenience [87891]. 3. The exploding oven door incident raised safety concerns for the users of the IKEA oven model and highlighted potential dangers associated with tempered glass doors [87891]. |
| Preventions | 1. Proper testing and quality control processes during the manufacturing of the oven door could have potentially prevented the incident. This includes ensuring the tempered glass used in the oven door is of high quality and less prone to shattering [87891]. 2. Implementing stricter safety measures and guidelines for the use and maintenance of the oven door, such as advising consumers not to subject the glass to undue impact or stress, could have helped prevent the door from exploding [87891]. 3. Regular monitoring and investigation of reported incidents related to the oven door's safety could have led to early detection of the issue, allowing for preventive actions to be taken before more incidents occurred [87891]. |
| Fixes | 1. Implementing a redesign of the oven door using a different type of glass that is less prone to exploding, such as using a different manufacturing process for the tempered glass [87891]. | References | 1.

| Recurring | unknown | The articles do not mention any software failure incidents related to either one_organization or multiple_organization. |
| Phase (Design/Operation) | design | Unknown |
| Boundary (Internal/External) | unknown | The articles do not mention any software failure incident related to the IKEA oven door explosion. Therefore, the boundary of the incident in terms of within_system or outside_system factors is unknown. |
| Nature (Human/Non-human) | unknown | The provided article does not contain information about a software failure incident related to non-human or human actions. Therefore, the answer to this question is 'unknown'. |
| Dimension (Hardware/Software) | unknown | The articles do not mention any software failure incident related to hardware or software. Therefore, the information about the software or hardware failure incident is unknown. |
| Objective (Malicious/Non-malicious) | unknown | <Article 87891> does not mention any software failure incident related to a malicious or non-malicious objective. Therefore, the information regarding the objective of the software failure incident is unknown. |
| Intent (Poor/Accidental Decisions) | unknown | Unknown |
| Capability (Incompetence/Accidental) | unknown | <Article 87891> does not mention any software failure incident related to development incompetence or accidental factors. Therefore, the information about the software failure incident related to these specific categories is unknown. |
| Duration | unknown | The articles do not mention any software failure incident related to the IKEA oven door explosion. Therefore, the duration of the software failure incident in this case is unknown. |
| Behaviour | other | (a) crash: The incident described in the article does not involve a software crash. The failure was related to the physical explosion of the oven door, leading to shards of hot glass scattering in the kitchen [Article 87891]. (b) omission: The incident does not involve a software omission. The failure was due to the tempered glass used in the oven door having a tendency to explode, causing shards to scatter [Article 87891]. (c) timing: The incident does not relate to a timing failure. The failure was not about the system performing its intended functions too late or too early [Article 87891]. (d) value: The incident does not involve a software failure related to the system performing its intended functions incorrectly. The issue was with the tempered glass in the oven door shattering, not with the oven's functionality [Article 87891]. (e) byzantine: The incident does not exhibit a byzantine behavior related to inconsistent responses or interactions of the system. The failure was due to the tempered glass in the oven door having a tendency to explode, leading to shards scattering in the kitchen [Article 87891]. (f) other: The behavior of the failure incident in this case is related to a physical failure of the oven door, specifically the tempered glass used in the door having a tendency to explode, causing hot glass shards to scatter in the kitchen. This type of failure is not directly related to software behavior but rather a design or material issue with the oven door [Article 87891]. |

| Consequence | unknown | The articles do not mention any software failure incident. Therefore, the consequence of the software failure incident is unknown. |
| Domain | unknown | The software failure incident reported in the news articles does not directly relate to any specific industry mentioned in the options provided. The incident described a physical failure of an IKEA oven door, which shattered and sent hot glass shards across the kitchen floor. The focus of the incident was on the safety concerns related to the tempered glass used in the oven door, rather than a software-related issue. Therefore, the incident does not fall under any of the specified industry categories. |
