The purpose of this study is to develop the measurement scales for consultative selling which has not been actively examined by the previous studies. This study, based on the analysis of how to execute consultative selling and the role of the salespeople in that process, identified 6 dimensions of consultative selling and developed items for each dimension. Initially through the literature review and salespeople focus group interview 48 items were developed. And then by reflecting the opinions of professors, sales consultants, sales managers and veteran salespeople about the initial items, several items were modified and several items were added. Finally 51 items were included in the survey. One hundred and sixty eight salespeople from various kinds of B2B companies participated in the survey. Using the exploratory factor analysis, 6 factors and 21 items were extracted. Each of the 6 factors were named 'careful selection of potential customers', 'extensive precontact research', 'identification of customized customer needs', 'creative value proposition', 'proactive mobilization of company resources', and 'improvement of long-term relationship with current customers'. Confirmatory factor analysis confirmed the meaningfulness of 6 factor structure and the additional analysis confirmed the discriminant validity of that structure. Finally managerial implications, limitations, and future research direction were discussed.
