The selection and evaluation of consultants, consultancies, and consulting services belong to probably the most critical issues in management consulting research. However, the research in these areas is still sparse and does not yet reflect their importance in an adequate manner. Additionally, in recent years new developments in management consulting have taken place, which have still not yet been covered. Observations of the consulting market indicate that both clients’ firms and consultancies have begun to professionalize their selection and evaluation procedures. This, in turn, changes the previous rules in the consulting market and stimulates the birth of new business models such as e-consultancies or meta consultancies. This book tries to capture these new developments, and intends to consolidate the existing research and stimulate new research implications in the area of selection and evaluation in management consulting.
