| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase can be seen in the case of Facebook's iPhone app update (3.4.3). The update was intended to fix bugs but ended up causing crashes, freezes, slowness, and other issues for users. This failure can be attributed to issues introduced during the system development and update process. Users reported problems with the chat mode not working and a host of other issues, indicating a failure in the design or development phase of the software [6894].
(b) The software failure incident related to the operation phase can be observed in the complaints from users about the performance issues with Facebook's iPhone app after the update to version 3.4.3. Users experienced crashes, freezes, and slowness, which are indicative of issues arising from the operation or use of the system. The failure in the operation phase is evident from the user complaints about the app not functioning properly after the update [6894]. |
| Boundary (Internal/External) |
within_system |
(a) within_system: The software failure incident related to Facebook's iPhone app was primarily within the system. The issues were caused by bugs within the app itself, leading to crashes, freezes, slowness, and a chat mode that didn't work. Users reported these problems after updating to version 3.4.3 of the Facebook iPhone app [6894]. Additionally, Facebook acknowledged that there were bugs in version 3.4.3 that caused performance issues, indicating that the failure originated from within the system [6894]. |
| Nature (Human/Non-human) |
non-human_actions, human_actions |
(a) The software failure incident occurring due to non-human actions:
- The software failure incident with Facebook's iPhone app was primarily due to bugs introduced in the 3.4.3 update released on June 29, which led to crashes, freezes, slowness, and other issues [6894].
- Facebook acknowledged that bugs in version 3.4.3 of the iPhone app caused performance issues, leading to the need for a new version (3.4.4) to address these problems [6894].
(b) The software failure incident occurring due to human actions:
- One potential factor contributing to the software failure incident was the lack of internal resources, with only one engineer working on Facebook's iPhone app full-time [6894].
- The departure of Joe Hewitt, the developer of the iPhone app, in May could have also impacted the app's maintenance and updates, as he switched to working on Facebook's Android app [6894]. |
| Dimension (Hardware/Software) |
software |
(a) The software failure incident related to hardware:
- The article does not mention any specific hardware-related issues contributing to the software failure incident [6894].
(b) The software failure incident related to software:
- The software failure incident is primarily attributed to bugs and glitches in the latest update (3.4.3) of Facebook's iPhone app, causing crashes, freezes, slowness, and issues with the chat mode [6894]. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the Facebook iPhone app update (3.4.3) does not appear to be malicious. Users reported crashes, freezes, slowness, and other issues after the update was released, indicating that the failure was likely due to unintentional bugs or faults in the update [6894]. Additionally, Facebook acknowledged the bugs in the app and was working on releasing a new version (3.4.4) to address the performance issues, which suggests a non-malicious intent to fix the problems [6894]. |
| Intent (Poor/Accidental Decisions) |
poor_decisions |
(a) The software failure incident related to the Facebook iPhone app update can be attributed to poor decisions made by Facebook. The article mentions that Facebook had only one engineer working on its iPhone app full-time, which could have contributed to the issues faced by users with the 3.4.3 update [6894]. Additionally, the decision to focus on a new mobile Web-based interface (Project Spartan) based on HTML5 instead of prioritizing the iPhone app may have also played a role in the failure [6894]. These poor decisions regarding resource allocation and priorities likely led to the software failure incident. |
| Capability (Incompetence/Accidental) |
development_incompetence, accidental |
(a) The software failure incident related to development incompetence can be seen in the case of Facebook's iPhone app update. The article mentions that the latest update (3.4.3) was supposed to fix bugs but instead caused crashes, freezes, slowness, and other issues, leading to a significant number of one-star reviews on the App Store [6894]. Additionally, it is highlighted that Facebook had only one engineer working on the iPhone app full-time, which could indicate a lack of sufficient internal resources dedicated to maintaining and improving the app [6894].
(b) The software failure incident related to accidental factors is evident in the case of the Facebook iPhone app update as well. The article mentions that the bugs in version 3.4.3 of the app led to performance issues, indicating that these issues were not intentional but rather unintended consequences of the update [6894]. |
| Duration |
temporary |
(a) The software failure incident related to Facebook's iPhone app can be considered temporary. The article mentions that the latest update (3.4.3) to the Facebook iPhone app introduced various bugs causing crashes, freezes, slowness, and other issues [6894]. Users were in an uproar over these problems, leading to almost 19,000 one-star reviews in the App Store. Facebook acknowledged the bugs and was working on pushing out a new version (3.4.4) to address the performance issues. This indicates that the failure was not permanent but rather a result of specific circumstances introduced by the update. |
