Technology adoption life cycle

The technology adoption lifecycle is a sociological model that describes the adoption or acceptance of a new product or innovation, according to the demographic and psychological characteristics of defined adopter groups. The process of adoption over time is typically illustrated as a classical normal distribution or "bell curve". The model indicates that the first group of people to use a new product is called "innovators", followed by "early adopters". Next come the early majority and late majority, and the last group to eventually adopt a product are called "Laggards" or "phobics." For example, a phobic may only use a cloud service when it is the only remaining method of performing a required task, but the phobic may not have an in-depth technical knowledge of how to use the service. The demographic and psychological (or "psychographic") profiles of each adoption group were originally specified by agricultural researchers in 1956: innovators – had larger farms, were more educated, more prosperous and more risk-oriented early adopters – younger, more educated, tended to be community leaders, less prosperous early majority – more conservative but open to new ideas, active in community and influence to neighbors late majority – older, less educated, fairly conservative and less socially active laggards – very conservative, had small farms and capital, oldest and least educated The model has subsequently been adapted for many areas of technology adoption in the late 20th century, for example in the spread of policy innovations among U.S. states. The model has spawned a range of adaptations that extend the concept or apply it to specific domains of interest. In his book Crossing the Chasm, Geoffrey Moore proposes a variation of the original lifecycle. He suggests that for discontinuous innovations, which may result in a Foster disruption based on an s-curve, there is a gap or chasm between the first two adopter groups (innovators/early adopters), and the vertical markets. Disruption as it is used today are of the Clayton M.

Modèle d'acceptation de la technologie

vignette|Modèle d'Acceptation de la Technologie tel que proposé par Davis, Bagozzi et Warshaw, Management Science 35(8), 1989 Le modèle d'acceptation de la technologie (MAT ou, plus fréquemment, TAM pour Technology Acceptance Model) est employé depuis 1989 pour tenter de prédire si un individu utilisera ou refusera d'utiliser une application informatique quelconque, d'entreprise ou grand-public, en fonction de deux facteurs : la facilité d'utilisation perçue de cette application et son utilité perçue.

Primo adoptant

thumb|Cycle de diffusion de l'innovation d'après Everett Rogers (1962). Un primo adoptant (en early adopter) est un client précoce d'un produit ou d'une technologie. Le terme original provient du livre Diffusion of Innovations (1962) d'Everett Rogers. Généralement, un primo adoptant sera un client qui, en plus d'utiliser le produit ou la technologie du fournisseur, participera également à évaluer ce dernier pour aider le vendeur à affiner ses futures versions de produits, ainsi que les moyens associés de distribution ou de service.

Diffusion of innovations

Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. The theory was popularized by Everett Rogers in his book Diffusion of Innovations, first published in 1962. Rogers argues that diffusion is the process by which an innovation is communicated over time among the participants in a social system. The origins of the diffusion of innovations theory are varied and span multiple disciplines.
