Contribution of management consultants to value creation: the case of consulting in Tunisia.

Summary The need for management consultants is a unifying point between theorists, practitioners, users of consulting and institutional actors. The problem lies in the fact that it is difficult to identify with precision the appropriate concepts and measures to evaluate the contributions of management consultants. In order to measure the contribution of management consultants, we proceeded to identify the type of contributions that can be made by them and the key success factors of the missions related to the consultant (or team of consultants) and the client (the client-system in general), and to set up measures that provide information on the double creation of value that can be achieved. The latter have been validated with a population of consultants and clients in the context of change management missions (such as assistance missions for the implementation of an information system) in Tunisia.
