Katz (1957) is also credited for first introducing the notion of opinion leaders, opinion followers and how the media interacts to influence these two groups. DOI is an enduring social science theory. Abrahamson examined this process critically by posing questions such as: How do technically inefficient innovations diffuse and what impedes technically efficient innovations from catching on? I. In 1962, Everett Rogers, a professor of rural sociology, published his seminal work: Diffusion of Innovations. [34][35], Unlike individual decisions where behavioral models (e.g. A system has a structure which due to interpersonal communication channels as farmer to farmer exchange of Communication channels also influenced the innovation decision process. [64], The first interests with regards to policy diffusion were focused in time variation or state lottery adoption,[65] but more recently interest has shifted towards mechanisms (emulation, learning and coercion)[66][67] or in channels of diffusion[68] where researchers find that regulatory agency creation is transmitted by country and sector channels. behaviour and does not reflect on prevention of behaviour. at various stages in order to reduce uncertainty about an innovation. Rate is usually measured by the length of time required for a certain percentage of the members of a social system to adopt an innovation. The theory characterizes five different groups of adopters. This model does not explain and predict the The Theory of Diffusion of Innovation answers several questions. complex and difficult to understand and use than its adoption by individual as the process by which an innovation is communicated through certain channels Whether the decision is made freely and implemented voluntarily, This page was last edited on 11 November 2020, at 05:41. They do have good exposure [7] Although each study applies the theory in slightly different ways, this lack of cohesion has left the theory stagnant and difficult to apply with consistency to new problems. These channels Diffusion of Innovation Theory. This is when the number of individual adopters ensures that the innovation is self-sustaining. Rogers’ diffusion of innovations theory is the most appropriate for investigating the adoption of technology in higher education and educational environments (Medlin, 2001; Parisot, 1995). According to the author, the There are characteristics of an innovation which determine its rate of adoption: Communication is the process one exchange of knowledge between two or more individuals. It is the abstraction of Emerson’s “better mousetrap”, and it has been identified as the most important predictor of an innovation’s adoption rate. While people might hear of an innovation's uses, in Rogers' Los Molinas sanitation case, a network of influence and status prevented adoption. Innovation is a broad category, relative to the current knowledge of the analyzed unit. The author distinguishes innovation decisions into Diffusion of Innovation (DOI) is a theory popularized by American communication theorist and sociologist, Everett Rogers, in 1962 that aims to explain how, why, and the rate at which a product, service, or process spreads through a population or social system Buyer Types Buyer types is a set of categories that describe spending habits of consumers. Since diffusion is more of a that individuals do not evaluate an innovation on the basis of scientific [56] The findings were that opinion leadership tended to be organized into a hierarchy within a society, with each level in the hierarchy having most influence over other members in the same level, and on those in the next level below it. From a social networks perspective, a failed diffusion might be widely adopted within certain clusters but fail to make an impact on more distantly related people. Or is it hard to replace old practices regardless how much new one is superior? The reintroduction of regulations in the early 2000s 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. [11] Diffusion of Innovations and Rogers' later books are among the most often cited in diffusion research. isolated and have limited resource and exposure to communication channels. The study of diffusion of innovations took off in the subfield of rural sociology in the midwestern United States in the 1920s and 1930s. popular model which explain how an innovative idea or technology is spread and adopted Early Majority have above average social status, contact with early adopters and seldom hold positions of, They adopt an innovation after the average participant. The diffusion of innovation theory analysis how the social members adopt the new innovative ideas and how they made the decision towards it. eventually curve begins to slow down as few individuals adopt innovation. The Diffusion of Innovation Theory was first discussed historically in 1903 by the French sociologist Gabriel Tarde (Toews, 2003) who plotted the original S-shaped diffusion curve, followed by Ryan and Gross (1943) who introduced the adopter categories that were later used in the current theory popularized by Everett Rogers. The hardware and software of technology are designed in a way to reduce uncertainty about achieving the desired outcome. The key elements in diffusion research are: Studies have explored many characteristics of innovations. 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. productivity. 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. first try but very interested in trying new things. And the real challenge was to change old An individual might reject an innovation at any time during or after the adoption process. different S-shaped curve. [33] The wider environment of the organization, often an industry, community, or economy, exerts pressures on the organization, too. Late According to the author, diffusion is a particular type of communication Rogers (2003) defined Diffusion of Innovation as “the process by which an innovation is communicated through certain channels over time among the members of a social system” (p. 3). The figure below shows both the type of adopters and S-curve. Therefore, an ideal situation would involve potential adopters who are homophilous in every way, except in knowledge of the innovation. These individuals approach an innovation with a high degree of skepticism and after the majority of society has adopted the innovation. [40] The rates of adoption for innovations are determined by an individual's adopter category. This stage is both intrapersonal (may cause. Even with this high learning curve, potential adopters might adopt the innovation anyway. social status. The Adoption theory is mainly useful when developing new products. An alternative term is 'policy transfer' where the focus is more on the agents of diffusion and the diffusion of policy knowledge, such as in the work of Diane Stone. Two rural sociologists Ryan and Gross did Other research relating the concept to public choice theory finds that the hierarchy of influence for innovations need not, and likely does not, coincide with hierarchies of official, political, or economic status. The social model proposed by Ryan and Gross[37] is expanded by Valente who uses social networks as a basis for adopter categorization instead of solely relying on the system-level analysis used by Ryan and Gross. The origins of the diffusion of innovations theory are varied and span multiple disciplines. possess power, status or technical expertise. [21] These are in line with the characteristics that Rogers initially cited in his reviews. The social and communication structure Innovativeness tells us which an individual or organization is Therefor, it is also hard to measure what are cause of adoption of Public consequences usually involve collective actors, such as countries, states, organizations or social movements. Finally, potential adopters who have the power or agency to create change, particularly in organizations, are more likely to adopt an innovation than someone with less power over his choices.[31]. opinions of others. awareness and knowledge about an innovation to target adopters. The process contains five stages that are slightly similar to the innovation-decision process that individuals undertake. However, the descriptions of the categories have remained similar throughout the editions. [58] Elites are often not innovators, and innovations may have to be introduced by outsiders and propagated up a hierarchy to the top decision makers. Late Majority are typically skeptical about an innovation, have below average social status, little financial liquidity, in contact with others in late majority and early majority and little. individual to see the results of an innovation then there are more chances of [25] Innovations that are disruptive to routine tasks, even when they bring a large relative advantage, might not be adopted because of added instability. following types. ... Diffusion of Innovations is a popular model which explain how an innovative idea or technology is spread and adopted and what are factors which influence this adaptation. Rogers states that this area needs further research because of the biased positive attitude that is associated with innovation. The explanation of such a pattern is not available in 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. Compatibility: New Product Adoption and Diffusion. The results are usually concerned with issues of societal well-being. [81], Such models represent a system of individuals as nodes in a network (or graph). Many studies have proven this interact with individual networks from other cities and countries. This led to the conclusion that advertising was best targeted, if possible, on those next in line to adopt, and not on those not yet reached by the chain of influence. able to cope with uncertainty about innovation and they do not depend on subjective The criterion for the adopter categorization is innovativeness, defined as the degree to which an individual adopts a new idea. The two-year educational campaign was considered to be largely unsuccessful. Incompatible innovations are difficult to be adopted. will be slow. Diffusion is the process by which an innovation is communicated through certain channels over time among the members of a social system (5). [32] Three organizational characteristics match well with the individual characteristics above: tension for change (motivation and ability), innovation-system fit (compatibility), and assessment of implications (observability). This model explains better adoption of Over time, each potential adopter views his neighbors and decides whether he should adopt based on the technologies they are using. corn from 1928 to 1941 and found that only two adopted hybrid corn early and compatible with existing values, norms, and needs of individual and social Compatibility of Technology, Complexity of Technology, Relative Advantage (Perceived Need for Technology) But rate of adoption took off Diffusion of innovation theory attempts to explain how an innovation is spread and why it is adopted at both the micro and macro levels of analysis. It is extremely difficult, if not impossible, to measure what exactly causes adoption of an innovation. system. Diffusion of innovations is a theory that seeks to explain how, why, and at what rate new ideas and technology spread. An alternative term is 'policy transfer' where the focus is more on the agents of diffusion and the diffusion of policy knowledge, such as in the work of Diane Stone. Relative advantage is the degree to which an innovation appears to be better than any other alternatives the potential adopter might have, measured in terms of economics, convenience, satisfaction, and social prestige. Rogers defined the diffusion Failed diffusion does not mean that the technology was adopted by no one. Due to the individualistic nature of this stage, Rogers notes that it is the most difficult stage on which to acquire empirical evidence. Complementary to the diffusion framework, behavioral models such as Technology acceptance model (TAM) and Unified theory of acceptance and use of technology (UTAUT) are frequently used to understand individual technology adoption decisions in greater details. Mathematical programming models such as the S-D model apply the diffusion of innovations theory to real data problems. The Diffusion of Innovations theory is concerned with the manner in which a new technological idea, product, technique, or a new use of an old one, moves from creation to use. These determine the success of a product. Using their definition, Rogers defines homophily as "the degree to which pairs of individuals who interact are similar in certain attributes, such as beliefs, education, social status, and the like". [28] Ability and motivation, which vary on situation unlike personality traits, have a large impact on a potential adopter's likelihood to adopt an innovation. The diffusion of hybrid seed was promoted by Iowa Agriculture Extension Rogers defines an adopter category as a classification of individuals within a social system on the basis of innovativeness. A social system has norms which Costs may be monetary or nonmonetary, direct or indirect. Using his synthesis, Rogers produced a theory of the adoption of innovations among individuals and organizations. Adoption is an individual process detailing the series of stages one undergoes from first hearing about a product to finally adopting it. system. Diffusion of innovations. From this definition, we identify four main elements in diffusion of new ideas: According to the author, innovation is a new idea, practice or object perceived by an individual or any other unit of adoption i.e organization. Time variable informs how individual decides about adopting innovation or rejecting innovation. communication, development studies, public health and organizational studies. The lowest levels were generally larger in numbers and tended to coincide with various demographic attributes that might be targeted by mass advertising. Diffusion of Innovation Theory Diffusion research examines how ideas are spread among groups of people. The champion plays a very similar role as the champion used within the efficiency business model Six Sigma. the S-shaped curve took off as 40% adopted in the next three years in 1936.
