The Diffusion of Innovation model, proposed by Everett Rogers, explores how new ideas, products, or practices spread and are adopted within a social system. It identifies five stages of adoption: awareness, interest, evaluation, trial, and adoption. It also categorizes individuals into innovators, early adopters, early majority, late majority, and laggards based on their propensity to adopt innovations. This model emphasizes the role of communication, social networks, and the influence of opinion leaders in the diffusion process. Understanding the diffusion of innovation helps businesses develop targeted strategies to accelerate adoption and maximize the impact of their innovative offerings.
