Organizational Development (OD) consultants often face dilemmas when they market their services because there is a gap between clients’ expectation and OD consultants’ role. This book is about how to overcome that dilemma by finding effective marketing strategies for a different approach to consulting. This book focuses on the challenges faced by internal and external consultants in marketing and selling their services. By distinguishing between performance consulting and Organization Development (OD) consulting, this book demonstrates why marketing and selling OD consulting services are unique. This book also delineates marketing and sales discipline to describe how these are different disciples. This book meets not only unique OD consultants’ need by reflecting the philosophical background of OD and unique marketing challenges but also HRD managers’ need who are interested in promoting or selling their change interventions within their organizations.
