This study empirically analyzed what consulting model has tendency to choose between fact-based model and process-based model and also analyzed which factors management consultants in Korea prefer when choosing consulting models. We concluded that in order to create performance on consulting projects, models of management consulting have been developed in a way either fact-based or action-based, not a mixed model. In addition, this study concluded that consulting performance is affected by professionalism, and consulting satisfaction during consulting projects is created by building interaction and trust with customers. Our major findings showed that the impact of professionalism on consulting performance would be higher than that of customer-orientation because consultants are qualified with professionalism. The impact of customer-orientation on consulting satisfaction would be higher than that of professionalism as consultants are qualified with customer orientation. This study, adopting questionnaire used in a precedent study, has a limitation with a view to the majority of respondents group that mostly consists of prospective consultants. In addition to, all of the variables used in the empirical study were collected from one source and this could have been a source of common method bias.
