The base case is an organisation with nodes N xA

With respect to the treatment of explanations, Wang and image Benbasat [85] rigorously developed and validated three types of explanations for RAs, namely, the how explanations, the why explanations, and the guidance. We adapted these explanations for this Y27632 research. In particular, the how explanations reveal the logical processes and the line of reasoning used by the RA. The why explanations justify the importance and the purpose of the questions asked by the RA to elicit users\' preferences, as well as the basis for the product advice provided. The guidance, also referred to as tradeoff [85], provides information about the options provided by an RA for its users to indicate their attribute preferences.
For RAs in the “with explanation” conditions, three buttons (corresponding to the three types of explanations) are provided for each question in the user–RA dialogue. When a user points the mouse to any of these buttons, the corresponding explanation is displayed on the screen (as shown in Fig. A2). In a pretest, we checked the comprehensibility of these explanations by asking pretest participants the extent to which sex linkage agreed with the statement “This explanation was easy to understand.” The how, why, and guidance explanations received average scores of 4.1, 4.2, and 4.2, respectively, on a five-point scale, indicating that these explanations were generally easy to understand. After the pretest, several suggestions regarding the clarity of wording were incorporated into the explanations used in the main experiment 2.
