“…Many of the methods that were used in safety-critical system design to involve expert users relied on mock-ups and prototypes to make the solutions tangible and to elicit users' experiences on the new designs (Healey et al, 2013;Koskinen et al, 2013b;Lu et al, 2007). The evaluation of mock-ups and prototypes was often also enriched with some scenario descriptions (i.e., series of hypothetical actions and events) or simulations emulating the key characteristics of that specific operating environment, thereby helping the users to experience the different functionalities of the proposed design solution (Hjelseth et al, 2015;Oggioni et al, 2021;Tideman et al, 2008). Another used method was applying different kinds of individual channels such as questionnaires and feedback reporting systems through which the expert users could express their opinions and concerns (dos Johannessen & Ellingsen, 2008).…”
