Solution:Rogers (1983) has developed a theoretical framework for diffusion of innovations based on his extensive study of agricultural innovations.Diffusion: Diffusion is formally defined as a process by which an innovation is communicated through certain channels over time, among the members of a social system.
The four main elements in this definition are innovation, communication channels, time and the social system. The key members of the social system are innovators, diffusers and adopters.
These are creators of innovations, intermediaries who assist in diffusing innovations, and target users of innovations, respectively. Rogers’ framework identifies the characteristics of these elements and provides an understanding of the role they play in the diffusion of innovations.
Innovation: Innovation is defined as an idea, a practice or an object which is perceived to be new by the persons who are targets for its adoption.
Communication Channel: Diffusion uses a communication process that results in the transmission of new ideas. In a diffusion context, this involves diffusers, adopters, and communication channels that connect them.
Time: Time is an important dimension in the study of diffusion for at least two reasons. First, diffusion is a continuous process which takes place over a period of time with a predictable life cycle of distinct stages.
Second, the level of adoption of any innovation as a function of time turns out to be a S-shaped curve, which has interesting implications.
Social System: The fourth element in Rogers’ framework is the social system. It is the environment in which diffusion processes take place and it includes aspects such as social structures, cultural norms and value systems.
