A Cognitive Work Analysis of Cardiac Care Nurses Performing Teletriage

A formative approach to the strategies analysis phase of cognitive work analysis

“…This can be done only by understanding the range of strategies possible and by identifying features of the work system that shape strategy selection and intervention outcomes. Whether a strategy is successful depends on the match between the strategy, the task, the worker and the situation , Can˜as et al 2003, Peters 2005, Naikar 2006, Burns et al 2009). …”

“…More recently, Burns et al (2009), Roth (2009 and Peters (2005) used interviews and observations to elicit strategies actually or potentially being used for problem solving in medical, railroad and university domains. However, Burns et al (2009) found that the empirical approach was not always successful.…”

“…Workers might also change how they perform the task while they are doing it, especially if circumstances change. The outcome from using a strategy can be success or failure, depending on the match between the worker, the strategy, the task and the situation , Can˜as et al 2003, Peters 2005, Naikar 2006, Burns et al 2009). Therefore, to make work systems as resilient as possible, designers must understand the range of strategies that workers can use to carry out tasks and the factors that lead to one strategy being selected over others.…”

“…Since Rasmussen's work, methods for performing Strategies Analysis have been developed and demonstrated by various researchers, including Vicente (1999), Ahlstrom (2005), Naikar (2006), Peters (2005), Hilliard et al (2008), Burns et al (2009), Roth (2009) and Cornelissen et al (2012). Nonetheless, much work reporting Strategies Analysis from the CWA perspective tends to present domain-specific strategies that workers recalled, or that investigators observed, albeit at different levels of generality.…”

Team Cognitive Work Analysis

“…CWA was developed explicitly for the purpose of analyzing complex systems in which unanticipated events could occur. CWA has shown success in modeling the work of single operators (e.g., Bisantz & Mazaeva, 2009;Burns, Enomoto, & Momtahan, 2009;Effken, Brewer, Logue, Gephart, & Verran, 2011;Flach & Amelink, 2003;Groppe, Pagliari, & Harris, 2009;Ho & Burns, 2003;Kilgore, St-Cyr, & Jamieson, 2009;Naikar, 2009), but relatively few attempts have been made to use CWA for modeling team situations (e.g., Ashoori & Burns, 2010;Burns, Torenvliet, Chalmers, & Scott, 2009;Burns & Vicente, 1995;Euerby & Burns, 2012;Naikar, Moylan, & Pearce, 2006;Rasmussen, Pejtersen, & Schmidt, 1990).…”
