As the IS discipline matures, it is important to establish common terms and definitions to achieve the long- sought goal of a cumulative tradition in the field. It is with this intent that this paper attempts to synthesize some key literature in the area of IS/IT adoption and implementation for developing the concept of “success of adoption” as the key adoption success construct. The paper further develops this construct and suggests that there are two dimensions to "success of adoption" - diffusion and infusion. The paper finally concludes by reconciling some terms that have been used in the IS adoption and implementation literature using this "success of adoption" construct.
