Consultants are brought into a business to analyse data around problems and challenges, and then offer expert advice and recommendations to address those issues.

A coach may indeed take on a consultancy approach at the initial stage of a coaching relationship, by asking insightful questions to determine what is really going on, what the specific objectives are, how they will be measured etc. but that is where the similarity ends. Subsequently, the coach will work with the client / organisation, as an equal partner, to find solutions, identify blocks and overcome the challenges, with no agenda other than to support the client.
