2.1 INTRODUCCIÓN
2.1.2 Análisis de los Sistemas
A study by Ryan and Gross (1943) was pivotal in establishing the theory of innovation diffusion. The researchers used funding from the Iowa Agriculture Experimental Station to study the dissemination of hybrid corn among growers. This quantitative study found the adoption process began with a small number of farmers who adopted hybrid corn soon after its release. When neighbouring farmers saw the results of this innovation, they quickly adopted the new strains of corn; thus a strategy of targeting influential farmers hastened the innovation process, facilitating greater productivity (Strang & Soule 1998).
By 1954, Rogers (1962) was part of another research team at the Experimental Station to study factors that militated against adoption of innovative farming practices. The insights gained from this research were crystallised from a plethora of research over the next half-century as Rogers explored factors affecting the adoption or rejection of innovative techniques. This culminated in the theory of innovation diffusion distilled in several versions of Rogers’ opus Diffusion of Innovation (Rogers 2003). Rogers (2003)
defined diffusion as ‘the process by which an innovation is communicated through certain channels over time among the members of social system’ (p. 5). The key elements in diffusion research are innovation, types of communication channels, time or rate of adoption, and the social system which frames the innovation decision process (Rogers 2003). The Diffusion of Innovation model includes five major characteristics:
• relative advantage: the degree to which it is perceived to be better than that
superseded;
• compatibility: consistency with exacting values, past experience, and needs; • complexity: difficulty of understanding;
53
• trialability: the degree to which it can be experimented on a no-limit basis;
and
• observability: the visibility of its results(Rogers 1962).
The innovation diffusion process, Rogers found, occurs in stages before and after the decision category. These stages assist investigators to understand factors and events in the diffusion process (see Figure 3.1).

Figure 3.1: Stages in the innovation-decision process
Rogers’s five stages of Diffusion Decision Process:
1. Knowledge: availability or perception of sufficient knowledge of the
innovation and its issues and outcomes to proceed;
2. Persuasion: when individuals seek reassurance from the innovator regarding
issues they raise;
3. Decision: based on existing knowledge, past experience and the information
from the innovator, an individual will accept or reject the innovation;
4. Implementation: when accepted, the individual harbours concerns regarding
the innovation, balanced by enthusiasm based on the innovator’s claims; and 5. Confirmation: when the adopter does not require further encouragement, and
on balance, accepts the innovation.
Adopter Categories, Rogers (2003) categorised the adopters into five groups, dependent on their engagement with innovation over time (Figure 3.2).
