Consultants offering services around change management and adoption generally fall into one of two categories. Either they support major technology implementation efforts by developing strategies for communication, training and change management that encourage adoption of the new technology, or they offer ad hoc strategies for improving the adoption of a firm's existing technology stack. Traveling Coaches is perhaps the best known vendor in the former space, though Fireman & Company has recently expanded its services here; Baretz + Brunelle offer services in the latter category.
