Duet consultants are experienced process consultants.
Edgar Schein, the guru of Process Consulting, explains:
“The process consultant can play a key role in sharpening the client’s understanding of what is wrong and how to deal with it, and may provide ideas and alternatives to consider that (which) may not have occurred to the client. But he strongly encourages the client to take ultimate responsibility for deciding what to do, how to intervene in the situation”.
(P 30 “Process Consultation – Volume 11 – Lessons for Managers and Consultants” Addison Wesley OD Series)
In our approach, you can see the overlap between Process Consulting and Coaching.
