| Recurring |
one_organization, multiple_organization |
(a) The software failure incident related to Sabre has happened again within the same organization. The article mentions that the same system experienced a failure in March, indicating a recurring issue within Sabre's software [83128].
(b) The software failure incident related to Sabre has also happened at multiple organizations. The article mentions that Sabre is not the only system of its kind, with major competitors like Amadeus, Travelport, and TravelSky. This suggests that similar incidents could potentially occur with these other systems as well [83128]. |
| Phase (Design/Operation) |
design, operation |
(a) The software failure incident related to the design phase can be attributed to the technical glitch experienced by a number of airlines due to the Sabre system. The article mentions that Sabre, a software system used by airlines for various purposes like tracking bookings and calculating baggage weight, experienced a failure causing delays and backups across the country [83128].
(b) The software failure incident related to the operation phase can be linked to the challenges faced in recovering from a glitch in the Sabre system. The article highlights that Sabre is responsible for tracking hundreds of millions of data points, and when a part of the system goes down, it creates a backlog, making the recovery process challenging [83128]. |
| Boundary (Internal/External) |
within_system, outside_system |
(a) The software failure incident involving Sabre, which caused delays for multiple airlines, was due to contributing factors that originated from within the system itself. Sabre is a crucial back-end system used by airlines for various functions like tracking bookings and scheduling flight crews. When the system experiences a glitch, it can have widespread effects on the global flight network, indicating that the failure was within the system [83128].
(b) Additionally, the article mentions that Sabre interfaces with various other systems, indicating that external factors could also contribute to the software failure incident. However, the primary cause of the delays and glitches was attributed to issues within the Sabre system itself [83128]. |
| Nature (Human/Non-human) |
non-human_actions |
(a) The software failure incident with Sabre system was due to non-human actions, specifically a technical glitch within the system itself. This glitch caused delays for multiple airlines and impacted various back-end functions like tracking bookings and calculating baggage weight [83128].
(b) The article does not mention any specific human actions contributing to the software failure incident. |
| Dimension (Hardware/Software) |
software |
(a) The software failure incident mentioned in the article was not attributed to hardware issues but rather to a technical glitch in the Sabre software system used by airlines [83128]. The glitch in the software caused delays and backups across the country, impacting the operations of multiple airlines.
(b) The software failure incident was specifically related to a technical glitch in the Sabre software system, which is a critical back-end system used by airlines for various functions like tracking bookings and scheduling flight crews [83128]. The article highlights how even a small snag in the software system can have significant ripple effects across the global flight network, emphasizing the importance of software reliability in such systems. |
| Objective (Malicious/Non-malicious) |
non-malicious |
(a) The software failure incident related to the technical glitch in the Sabre system that caused delays for airlines was non-malicious. The glitch was not caused by any malicious intent but rather by a technical issue within the system itself, leading to backups across the country [83128]. |
| Intent (Poor/Accidental Decisions) |
unknown |
(a) The software failure incident related to the Sabre system causing delays for airlines was not due to poor decisions but rather a technical glitch in the system itself. The incident was attributed to a snag in the software, which caused backups across the country, affecting airlines like Alaska, American, and JetBlue [83128].
(b) The software failure incident was not due to accidental decisions but rather a technical glitch in the Sabre system, which is a crucial back-end system used by airlines for various functions like tracking bookings and calculating baggage weight. The failure was not a result of mistakes or unintended decisions but rather a system issue that caused disruptions in airline operations [83128]. |
| Capability (Incompetence/Accidental) |
accidental |
(a) The software failure incident related to development incompetence is not explicitly mentioned in the provided article. Therefore, it is unknown whether the failure was due to contributing factors introduced due to lack of professional competence by humans or the development organization.
(b) The software failure incident related to an accidental cause is mentioned in the article. The article describes how a technical glitch in the Sabre system, a crucial software system used by airlines, caused delays and backups across the country. This glitch was not intentional but occurred accidentally, leading to disruptions in airline operations [83128]. |
| Duration |
temporary |
(a) The software failure incident related to Sabre causing delays for airlines was temporary. The article mentions that the technical glitch in the Sabre system caused delays for airlines on Monday, but it was not a permanent failure. The effects of the glitch rippled across the global flight network, but the system was eventually fixed [83128]. |
| Behaviour |
crash, value, other |
(a) crash: The software failure incident related to Sabre system experiencing a technical glitch causing delays for airlines can be categorized as a crash. The glitch led to backups across the country, impacting the airlines' operations and causing frustration among travelers [83128].
(b) omission: The article does not specifically mention the failure as an omission where the system omitted to perform its intended functions at an instance(s).
(c) timing: The software failure incident related to the Sabre system does not align with a timing failure where the system performed its intended functions too late or too early.
(d) value: The failure of the Sabre system can be attributed to a value failure as it did not perform its intended functions correctly, leading to delays and disruptions in airline operations [83128].
(e) byzantine: The software failure incident related to the Sabre system does not exhibit a byzantine behavior where the system behaves erroneously with inconsistent responses and interactions.
(f) other: The behavior of the software failure incident can be described as a glitch that caused disruptions in the airline operations, impacting the system's reliability and leading to delays across the global flight network [83128]. |
