TheHandbook concludes with an assessment of areas of future research and debate. By bringing together a wide range of research and thinking on management consultancy across different disciplines, sub-disciplines, and conceptual approaches, the Handbook provides a comprehensive understanding of both current thinking and future directions for research.
