“…Perhaps no scholar is clearer about this distinction as van der Heijden (, p. 114) when stating that “[e]xternal scenarios are derived from shared and agreed upon mental models of how the external world works,” which “is the part of the environment where we have little or no influence, but which impacts on us in a major way.” Reference to events in the external environment typically render them as sequences of events, as in Kahn and Weiner’s (, p. 6) view of scenarios as “hypothetical sequences of events,” or as a course of events, as in Dyner and Larsen’s (, p. 1,152) references to dictionary definitions of scenarios as “stories about how the future could be or, as one dictionary describes it: “an outline of a natural or expected course of events.”” Reference to conditions is varied, but is always contextual, and includes “current conditions” (Swart et al, , p. 139), “test conditions” (van der Heijden, , p. 114), or, more generally, “the conditions under which the systems ... are assumed to be performing” (Brown, , p. 299‐300). Similarly, situation is varied but contextually‐oriented (Aligica, , p. 309; Durance & Godet, , p. 1,488); situations can be “anticipated” (Gordon, , p. 3), “current” (van der Heijden, , p. 153), in the “present” (Heinecke, & Schwager, , n.p. ), or “possible” (Gracht & Darkow, , p. 47).…”
