Evaluation of the diffusion of innovation theory

When promoting an innovation to a target population, it is important to understand the characteristics of the target population that will help or hinder adoption of the innovation. Two major communication channels were described by Rogers: They enjoy leadership roles, and embrace change opportunities.

Diffusion signifies a group phenomenon, which suggests how an innovation spreads. Laggards - These people are bound by tradition and very conservative. The pro-innovation bias, in particular, implies that all innovation is positive and that all innovations should be adopted.

Diffusion of Innovation Theory

Observability - The extent to which the innovation provides tangible results. These individuals typically have an aversion to change-agents. Extensions of the theory[ edit ] Policy[ edit ] Diffusion of Innovations has been applied beyond its original domains.

The key to adoption is that the person must perceive the idea, behavior, or product as new or innovative. In contrast Wejnert details two categories: It originated in communication to explain how, over time, an idea or product gains momentum and diffuses or spreads through a specific population or social system.

Over time, each potential adopter views his neighbors and decides whether he should adopt based on the technologies they are using. Katz is also credited for first introducing the notion of opinion leaders, opinion followers and how the media interacts to influence these two groups.

Conclusion The Diffusion of Innovation theory is a very important theory that can serve administrators, information technologists, nursing informatics experts, and change agents well. The multiple parameters that influence decisions to adopt, both individual and socially motivated, can be represented by such models as a series of nodes and connections that represent real relationships.

These technologies include radio, television, VCR, cable, flush toilet, clothes washer, refrigerator, home ownership, air conditioning, dishwasher, electrified households, telephone, cordless phone, cellular phone, per capita airline miles, personal computer and the Internet.

The residents had no knowledge of the link between sanitation and illness. Late Majority - These people are skeptical of change, and will only adopt an innovation after it has been tried by the majority. The lowest levels were generally larger in numbers and tended to coincide with various demographic attributes that might be targeted by mass advertising.

These individuals approach an innovation with a high degree of skepticism and after the majority of society has adopted the innovation. The person implementing the change controls the direction and outcome of the campaign.

Rate of Adoption — time is also involved when looking at the ultimate rate of adoption, say within an organization, from start to finish, and how many people of the total population have adopted the innovation. Time Time is involved in three distinct dimensions of the innovation process Innovation Adoption Process — including first knowledge of the innovation through to final acceptance or rejection of its utility and ultimate implementation, as discussed earlier.

Within this theory, the goal is not to move people within the five adopter categories into another category, but to streamline the innovation to meet the needs of all five categories. The theory fits nursing informatics well, and provides a scaffold for planning informatics related innovations.

Behavioral Change Models

Failed diffusion[ edit ] Failed diffusion does not mean that the technology was adopted by no one. It is quite important for a marketer to understand the diffusion process so as to ensure proper management of the spread of a new product or service.

Unlike some of the previous categories, individuals in this category show little to no opinion leadership. It is extremely difficult, if not impossible, to measure what exactly causes adoption of an innovation. They do not need information to convince them to change.

In public health, Diffusion of Innovation Theory is used to accelerate the adoption of important public health programs that typically aim to change the behavior of a social system.

It does not foster a participatory approach to adoption of a public health program. Electronic communication social networks[ edit ] Prior to the introduction of the Internet, it was argued that social networks had a crucial role in the diffusion of innovation particularly tacit knowledge in the book The IRG Solution — hierarchical incompetence and how to overcome it.

People tend to be close to others of similar health status. The Two-Step Flow of Communication: Innovators - These are people who want to be the first to try the innovation. As a result, homophilous people tend to promote diffusion among each other.

Potential adopters have a threshold, which is a fraction of his neighbors who adopt the innovation that must be reached before he will adopt. Rogers states that this area needs further research because of the biased positive attitude that is associated with innovation. The adoption of an innovation follows an S curve when plotted over a length of time.

These characteristics also provide a valuable evaluation list for technology project leaders to apply when first considering innovative changes. Adoption means that a person does something differently than what they had previously i.The most striking feature of diffusion theory is that, for most members of a social system, the innovation-decision depends heavily on the innovation-decisions of the other members of the system.

In fact, empirically we see the successful spread of an innovation follows an S-shaped curve (23). The diffusion of innovation theory does not quite give a clear prediction of how the innovation will be successful after going through the S curve.

An innovation may mutate in the process of diffusion thereby affecting the diffusion process. Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers inis one of the oldest social science theories.

It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system.

Diffusion of innovations

The end result. Diffusion of Innovations Theory Diffusion of innovations is a theory profound by Everett Rogers that seeks to explain how, why, and at what rate new ideas and technology spread. Rogers argues that diffusion is the process by which an innovation is communicated over time among the.

Diffusion of Innovations Diffusion of Innovations seeks to explain how innovations are taken up in a population. An innovation is an idea, behaviour, or object that is perceived as new by its audience.
