"DoI Theory is concerned with the manner in which a new technological idea, artefact or technique, or a new use of an old one, migrates from creation to use. According to DoI theory, technological innovation is communicated through particular channels, over time, among the members of a social system.

The stages through which a technological innovation passes are:
knowledge (exposure to its existence, and understanding of its functions);
persuasion (the forming of a favourable attitude to it);
decision (commitment to its adoption);
implementation (putting it to use); and
confirmation (reinforcement based on positive outcomes from it). "

- unique (“a universe of one”) " requiring learning when no one knows the
answer"
