Diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system (5). Given that decisions are not authoritative or collective, each member of the social system faces his/her own innovation-decision that follows a 5-step process (162):
1) Knowledge – person becomes aware of an innovation and has some idea of how it functions,
2) Persuasion – person forms a favorable or unfavorable attitude toward the innovation,
3) Decision – person engages in activities that lead to a choice to adopt or reject the innovation,
4) Implementation – person puts an innovation into use,
5) Confirmation – person evaluates the results of an innovation-decision already made.
