This study compared how people working in three different types of organisations in the United States (K-12 schools, higher education, and business) rank the importance of eight conditions that have been shown to facilitate the implementation of innovations. The study also sought to determine if the nature of the innovation (i.e., technology or process innovation) affected the rankings. Technology innovations are those that require the use of a new tool or product such as an innovative communications device or new piece of manufacturing equipment. Process innovations are those that require a new method or system such as a new method for performance evaluations or new budget approval process. A total of 635 participants completed an online instrument to determine their individual ranking of the eight conditions, 315 participants responded to questions specific to technology innovation while 320 responded to process specific questions. Analysis of variance was used to compare differences between the groups. Significant differences were found on five of the eight conditions in the technology sample and on seven of the eight conditions in the process sample. In addition, there were differences within groups based on the nature of the innovation. Change agents must adapt their strategies to account for the different rankings of the eight implementation conditions based on type of organisation and the nature of the innovation. The results of this study provide a framework for understanding and accounting for the group differences. This is the first study to address the prescriptive value of the eight implementation conditions. (Contains 4 tables.)
