Consider a case where factors that influence technology adoption are identified from literature review and recency/frequency of relevant keywords from available literatures. Now, in order to perform factor analysis/scenario analysis using fuzzy cognitive mapping (FCM) (FCM combines cognitive mapping with artificial neural networks (ANN)) how weights can be assigned to the influencing factors? If it involves collection of survey based primary data then briefly explain the method. Also briefly explain other sources of data. Which sampling method(s) to be used?
