In contract management, the role of Contract Managers changes on the type of an organization. One of the differences between organizations lies in the extent of authority and accountability that Contract Managers have for making contract changes. Another difference is the extent to which the Contract Manager’s function in the organization has solely deal-based responsibility, versus a more strategic role in overall company policy and commercial / contractual strategy. For example, does the function simply implement and protect other people’s rules, or does it advocate change and participate in key policy discussions? It is thus, the needs of an organization which dictates the roles of contract management personnel.
