Diffusion of innovations is a theory profound by Everett Rogers that seeks to explain diffusion is the process by which an innovation is communicated over time. The Process of Innovation and the. Diffusion of Innovation. THOMAS S. ROBERTSON. "Innovate or Perish" is the nnarketer's cry of the. s. And " Perish as. The origins of the diffusion of innovations theory are varied and span across ..

The reintroduction of regulations in the early s also shows this learning process, which would fit under the stages of knowledge and decision, can be seen as lessons learned by following China's successful growth.
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. These data  can act as a predictor for future innovations. Diffusion curves for infrastructure  reveal contrasts in the diffusion process of personal technologies versus infrastructure.
Consequences of adoption[ edit ] Both positive and negative outcomes are possible when an individual or organization chooses to adopt a particular innovation. Rogers states that this area needs further research because of the biased positive attitude that is associated with innovation. In contrast Wejnert details two categories: public vs. Public consequences usually involve collective actors, such as countries, states, organizations or social movements.
The results are usually concerned with issues of societal well-being. Private consequences usually involve individuals or small collective entities, such as a community. The innovations are usually concerned with the improvement of quality of life or the reform of organizational or social structures.
Costs may be monetary or nonmonetary, direct or indirect. Direct costs are usually related to financial uncertainty and the economic state of the actor. Indirect costs are more difficult to identify. An example would be the need to buy a new kind of pesticide to use innovative seeds. Indirect costs may also be social, such as social conflict caused by innovation. 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.
Main article: Logistic function The diffusion of an innovation typically follows an S shaped curve which often resembles a logistic function. Mathematical programming models such as the S-D model apply the diffusion of innovations theory to real data problems. The interactions that link these individuals are represented by the edges of the network and can be based on the probability or strength of social connections.
In the dynamics of such models, each node is assigned a current state, indicating whether or not the individual has adopted the innovation, and model equations describe the evolution of these states over time.
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. Borrowing from social network analysis, each node is an innovator, an adopter, or a potential adopter.
Potential adopters have a threshold, which is a fraction of his neighbors who adopt the innovation that must be reached before he will adopt. Over time, each potential adopter views his neighbors and decides whether he should adopt based on the technologies they are using. When the effect of each individual node is analyzed along with its influence over the entire network, the expected level of adoption was seen to depend on the number of initial adopters and the network's structure and properties.
Two factors emerge as important to successful spread of the innovation: the number of connections of nodes with their neighbors and the presence of a high degree of common connections in the network quantified by the clustering coefficient. These models are particularly good at showing the impact of opinion leaders relative to others. It is extremely difficult, if not impossible, to measure what exactly causes adoption of an innovation.
Those encouraging adoption of health behaviors or new medical technologies need to be aware of the many forces acting on an individual and his or her decision to adopt a new behavior or technology. Diffusion theories can never account for all variables, and therefore might miss critical predictors of adoption. The pro-innovation bias, in particular, implies that all innovation is positive and that all innovations should be adopted.
The message sender has a goal to persuade the receiver, and there is little to no reverse flow.
They usually rely on the the categories in relation to the adoption information provided by early adopters to use of technological products in business. His a new technology or an innovation. Early majorities between early adopters and early majority.
His interpretation can be of fads.

They are purely cautious people towards adoption of a new innovation. Some of them are so worried that they stay awake all night, tossing and turning, thinking up arguments against it Les Robinson, Because of the limited resources and the lack Figure 2: Attributes of an Innovation Despite their dissent towards innovations, they may sometimes prompt the innovator in Regardless of the nature and characteristics bettering the innovation itself.

Behavioral Change Models
Rogers and Shoemaker that the chasm — the different needs of early observed that five attributes of an innovation majority compared to early adopters — needs are largely involved to influence the adoption to be bridged if an innovation is going to be of an innovation; 1 relative advantage, successful in the mass market.
Moore describes 2 compatibility, 3 complexity, 4 trial- the common delay that accompanies diffusion ability, and 5 observability. It helps give determine between 49 and 87 percent of the meaning to the new idea and regard it variation in the adoption of new products Les as more familiar Francesco, The Robinson, Relative Advantage: A simple yet a which wants to introduce a new line of powerful concept for diffusion of an operations will find it suitable to have a innovation.
If idea, a new product or a service if he the new line will disrupt the existing perceives it to be a better option that operational lines it may increase the cost the one in practice. If a user finds a new involvement and the firm may scrap the innovation more advantageous than the deal.
However one shall not blank out this operational one he will be compelled to possibility that two much compatibility adopt to the new innovation. Thus more can be sometimes a problem as the advantageous the new innovation the users may find it unworthy to try a new more quickly will it diffuse in a social innovation or might not perceive it to be system.
The degree of relative advantage an innovation. Opposite to other attributes The other elements of innovation this attribute has an inverse impact on diffusion like communication channels the rate of adoption of an innovation.
This over current practices and objects. The may not hold good in all situations as faster and reliable the communication some high tech products are perceived system the quicker the rate of diffusion more advantageous because of their of an innovation.
It was reported that adopting the innovation is compatible farmers in the Sudan did not accept new with what people do Kaasinen, It is the degree of examining follow Barnett, It is the easiness with actually adopting to it. Simple example which the results of an innovation are of trainability is the test drive offers not only visible but their communication by the automobile companies where to the prospective users.

It gives the prospective system is able to share the results of an users a sense of sureness to adopt to a innovation the faster its rate of adoption. Triability determines E. Tornatzky and Klein identified This creates a sense of assurance five more attributes of an innovation.

Other researchers have extended degree of exposure to public notice. Trust as the extent to Visibility is the degree to which which the innovation adopter perceives the others can see that an innovation is innovation provider to be trustworthy.
Whether a person actually users to take up internet connections. Roger takes the innovation into experimental and Shoemaker and Rogers and Beal use or applies it on a smaller scale. At this stage the an innovation passes before an individual innovation is taken into continual full takes it into use: Innovation-decision process and information about the innovation.
Figure 3. The Persuasion Stage: Persuasion occurs PROCESS when an individual or other decision- The innovation-decision process is the making unit forms a favourable or process through which an individual or unfavourable attitude toward the other decision-making unit passes from first innovation Rogers, However knowledge of an innovation to forming an Rogers argues that the positive or negative attitude toward the innovation, to a decision attitude formation about the innovation to adopt or reject, to implementation of the may not be directly involved in the decision new idea, and to confirmation of this decision of adoption or rejection of an innovation.
The five steps identified in the A person only forms an attitude about process of Innovation-Decision are: Thus the persuasion stage 1. The Knowledge Stage: The first step of correctly follows the knowledge stage. In this stage more latent and but affective more like the individual comes to know about the feeling centred while as knowledge stage being of an innovation.
The existence is cognitive and known.
Diffusion of Innovation Theory
It is in this stage of an innovation becomes known to a that the uncertainty revolving the use of person through communication channels. The reasons that individuals usually questions posed by an individual cause trust information from close circle peers three types of knowledge formation: Awareness- and filter the information coming from knowledge represents the knowledge outside this circle.
How-to- knowledge: The other type of knowledge, 3. The Decision Stage: Decision occurs when an how-to-knowledge, contains information individual or other decision-making unit about how to use an innovation correctly. The last knowledge to adopt or reject the innovation Rogers, type is principles-knowledge.
This It is chances of adoption or acceptance by the because of these circumstances that the individuals.
The same may not hold good information flow keeps on displacing for all innovations. Rogers says from users to other people. Uncertainty that in the decision stage the individual about the outcomes of the innovation decides to adopt or reject the technology. An individual perceives the innovation favourable and intends to 5. The Confirmation Stage: The lag of time Human behaviour change is motivated in may be because of monetary or other part by a state of internal disequilibrium social issues.
An individual adopts to or eliminate Rogers, According an innovation but rejects it afterwards. The individual is made about an innovation it is human rejects the innovation from its outset and behaviour to seek information about the continues to do so.
The Implementation Stage: In this stage the off the innovation. Rogers argues innovation is applied in daily use or one can that even after the decision of adoption is say the innovation is put to practice.
However, the individual tends exercise. But implementation involves to stay away from these messages and seeks overt behaviour change, as the new idea is supportive messages that confirm his or actually put into practice Rogers, It is in Implementation stage can prove to be a this stage that attitude of a person towards difficult task for a user.
The discontinuance that may idea in a specified period.
So rate of adoption occur in this stage can be of two types: Strategies to appeal to this population include information on how many other people have tried the innovation and have adopted it successfully. Laggards - These people are bound by tradition and very conservative.
They are very skeptical of change and are the hardest group to bring on board. Strategies to appeal to this population include statistics, fear appeals, and pressure from people in the other adopter groups. There are five main factors that influence adoption of an innovation, and each of these factors is at play to a different extent in the five adopter categories. Relative Advantage - The degree to which an innovation is seen as better than the idea, program, or product it replaces.
Compatibility - How consistent the innovation is with the values, experiences, and needs of the potential adopters.
Triability - The extent to which the innovation can be tested or experimented with before a commitment to adopt is made. Observability - The extent to which the innovation provides tangible results. Limitations of Diffusion of Innovation Theory There are several limitations of Diffusion of Innovation Theory, which include the following: Much of the evidence for this theory, including the adopter categories, did not originate in public health and it was not developed to explicitly apply to adoption of new behaviors or health innovations.
It does not foster a participatory approach to adoption of a public health program. It works better with adoption of behaviors rather than cessation or prevention of behaviors. It doesn't take into account an individual's resources or social support to adopt the new behavior or innovation. This theory has been used successfully in many fields including communication, agriculture, public health, criminal justice, social work, and marketing.This presents a critical challenge for health communications, as ties between heterophilous people are relatively weaker, harder to create, and harder to maintain.
One must admit the smartphones. Organizations face more complex adoption possibilities because organizations are both the aggregate of its individuals and its own system with a set of procedures and norms. The theory also benefits the targets of change, since respect and consideration for all involved stakeholders is intertwined with robust strategies for implementing innovative change. The key to adoption is that the person must perceive the idea, behavior, or product as new or innovative.
Why is that? Rogers synthesized research from over diffusion studies across the fields that initially influenced the theory:
