“…FsQCA accepts alternative combinations of causal conditions, equifinality and asymmetry (Fiss, ) that when applied to the present case, allow for more than one combination (or configuration) of causal conditions that lead to ROI; alternative causal configurations can lead to ROI, and causal conditions of ROI can differ from causal conditions of its absence. Although several antecedents of training results can be considered, we are limited by the existing data and opt to use four factors that influence the values of the ROI for training programs: (1) the program’s topic (Chochard & Davoine, ; Fregonese et al , ; Giangreco et al , ; Grohmann & Kauffeld, ), (2) its number of participants (Chochard & Davoine, ; Giangreco et al , ), its duration (Chochard & Davoine, , ; Dmitry & Manokhina, ; Giangreco et al , ; Grohmann & Kauffeld, ) and (3) its cost (Asadullah et al , ; Dmitry & Manokhina, ). Thus, the causal conditions in this study are the variables related to each training program: Training topic (top), Number of participants (part), Duration (dur) and Total cost (cost).…”
