As technology systems have become more complex, so it is increasingly difficult for human operators to comprehend how the system is behaving. There is a need to better understand the causes of human-error in the context of the situational variables. The specific case under examination is the process of landing an aircraft. This paper applies a production engineering perspective. By production-process, we refer to the set of actions that are necessary to move a system from one state to a desired new state. Such processes involve mechanisms for taking inputs and converting them to the desired outputs, under certain controls and constraints. Human error is thus treated as a constraint on the processes. A novel process methodology is developed to represent how technical systems, situational variables, external factors, and human error evolve over time in a process. The applicability is demonstrated with a dataset of case studies. In parallel, a new categorization of human errors is derived for this situation. The method permits cases to be examined individually, and also collectively for patterns. The results show that the initial landing approach is often the point of error initiation. For the specific case of landing accidents the methodology identifies that the failure causality was the lack of attention to establish procedure at the very start of descent, followed by persistent disregard of disconfirmatory evidence at the initial landing approach, especially under conditions of poor visibility. The paper makes a methodological contribution as well as suggesting new insights for how human error occurs at landing.

“…These objective measures correlated with subjective ratings of cognitive workload by the pilots. 22 Similarly, in the TGC protocol, the blood glucose level has to be interpreted in context of the current, possibly physiologically complex state of the patient when that data was obtained. Svensson and colleagues study suggests that this interpretation might be easier for expert nurses than for less experienced nurses.…”

Abbreviations: (ICU) intensive care unit, (TGC) tight glucose controlKeywords: computerized decision support, nursing staff, insulin, practice guidelines, protocols, tasks, work SYMPOSIUM AbstractCritically ill patients require intensive nursing care. Intensive care unit (ICU) nurses, who care for these physiologically unstable patients, are continuously occupied with the integration of assessments, monitoring, and interventions that are responsive to a patient's evolving state. Since 2005, numerous evidenced-based clinical protocols have been implemented in the critical care unit. Individually, each may not appear to be burdensome but, collectively, these clinical protocols add to the cognitive work of ICU nurses. While nurses are central to the successful implementation of these protocols, little is written about the cognitive burden imposed on them by the addition of these clinical protocols. This article explores the impact of clinical protocols on the cognitive burden of ICU nurses, using a tight glucose control (TGC) protocol as an exemplar case. Research from management, ergonomics, systems engineering, and nursing is used to build the concept of cognitive burden. Future research can build upon this understanding to facilitate successful implementation of clinical protocols.

“…Gaze tracking systems have become tools in usability studies, where researchers are interested in recording the eye movements of humans as they interact with computer interfaces [32], navigate websites [9], perceive advertising in the Yellow Pages [55] and even fly a plane [93]. In addition to recording eye gaze for subsequent analysis, the human computer interaction (HCI) community has studied real-time eye gaze tracking systems as input devices [44].…”
