The authors present survey results from faculty at 44 universities on the role of student consulting projects in developing business students' critical thinking. They conclude that students can improve critical thinking by engaging in guided primary and secondary research to inform their business assumptions that underpin business planning and financial modeling in consulting projects. Results also suggest that instructors newer to the practice of using student consulting tend to emphasize objective results (e.g., application of disciplinary skills and research methods), whereas experienced users seem to focus on the subjective consulting process (e.g., managing client relationships and evaluating information quality and fit for the project).
