Dear colleagues, I am conducting a research regarding discontinuance of an innovation (an intranet), but I am troubled in conceptualizing/operationalizing discontinuance. In Rogers' framework, discontinuance is located in confirmation stage and mainly occurs due to dissonance between users' expectation and the functions/results provided by the innovation, and negative information obtained from users' communication network. And, Rogers (1983) argues that 'discontinuance is one indication of incomplete routinization and institutionalization.' The point is, however, that routinization and institutionalization should be achieved during implementation stage, which is why Rogers posits that actual innovation adoption process ends here. So, my question is whether we should understand routinization and institutionalization as pre-conditions for discontinuance or not. In addition, in Rogers' model, actual use starts at implementation stage since adoption stage concerns mental process rather than behavioral change. Thus, implementation stage intrinsically includes trials and evaluations. If, this understanding is correct, a seemingly important questions raise; why we need a separate stage of confirmation; if implementation and confirmation differ, what we confirm during confirmation stage; if confirmation stage aims to confirm the existence of new innovations (ideas) including comparisons between an adopted innovation and new innovations, confirmation stage intrinsically includes components of a new innovation adoption process.
