Okoli et al. (2013) asserted that critical decision-making process is a retrospective interview approach that utilizes a set of cognitive inquiries to specific non-routine incidents that required expert judgment or decision making (Klein, Calderwood & MacGregor, 1989; cited in Okoli et al., 2013). CDM was preferred to others within the cognitive task analysis family for two reasons: First, CDM produces a robust theoretical basis, and it is highly instrumental in defining the emerging field of Naturalistic Decision Making (Hoffman, Crandall, & Shadbolt, 1998; cited in Okoli et al., 2013). Second, CDM has remained widely used in different ways to elicit expert knowledge across different domains. Hence, the validity and reliability of CDM have continued proven (Wong, 2000; cited in Okoli et al.,
