When implementing an innovation, a multitude of components interact to change not only the users, but the innovation as well. This guide explains the concept of innovation configurations, or adaptations made in innovations during implementation. After presenting and discussing past research on innovation changes, the report outlines a five step procedure for identifying these changes. A one year study testing these steps is described. The report concludes with a discussion of problems arising in implementation and evaluation of an innovation, including evaluator subjectivity, degree of change in the individual or innovation, and the complete alteration of the innovation.
