The Rogers’ Innovation Adoption Curve, developed by communication theorist Everett Rogers, also known as Diffusion of Innovations theory, explains how new ideas or innovations spread within a population or a social group. It’s a useful framework to understand how change is often adopted unevenly and at different rates through an organisation.

The curve is divided into five main segments representing different groups of adopters and is commonly used to strategize and tailor communication approaches based on the characteristics of each group. Here are the key ideas:

Adoption Groups

Innovators (2.5%)

  • Innovators are the first individuals to adopt a new idea or technology.
  • They are risk-takers and are eager to try new things.
  • Innovators often have a high social status and financial resources.

Early Adopters (13.5%)

  • Early Adopters are the second group to adopt innovations.
  • They are opinion leaders in their social circles and are well-connected.
  • Early Adopters carefully consider and evaluate new ideas before adopting them.

Early Majority (34%)

  • The Early Majority represents the average members of a social system.
  • They adopt innovations after seeing the success and acceptance by the Innovators and Early Adopters.
  • Early Majority members seek information from early adopters before making decisions.

Late Majority (34%)

  • The Late Majority adopts innovations after the average member of the social system has accepted them.
  • They may be sceptical of change and adopt new ideas out of necessity rather than willingness.

Laggards (16%)

  • Laggards are the last to adopt innovations.
  • They are resistant to change and may only adopt when it becomes necessary for survival.
  • Laggards often rely on traditional methods and are skeptical of new ideas.

Critical Mass

Critical Mass is the point at which the adoption of an innovation becomes self-sustaining. Once a critical mass of the population has adopted an innovation, it tends to spread more rapidly. This usually occurs when the Early Majority begins to adopt the change.

The Chasm

In the context of the Innovation Adoption Curve, the “chasm” is a concept introduced by Geoffrey A. Moore in his book “Crossing the Chasm’. Moore’s book builds upon Everett Rogers’ Diffusion of Innovations theory and focuses on the challenges that innovations face when transitioning from early adoption to mainstream adoption.

In the context of change management, the chasm represents a gap or a discontinuity between the Early Adopters (those who are open to trying new ways of working) and the Early Majority (the pragmatists who adopt new methods more cautiously).

Successfully crossing the chasm is crucial for a change management project to achieve widespread adoption and implementation.

While Innovators and Early Adopters are often motivated by novelty and being first to try new things, the Early Majority are pragmatists who need more concrete evidence of an innovation’s value and reliability. This is when the communication strategy needs to shift from an emphasis on novelty and originality to messages based on practical needs and a clear value proposition of the benefits to this change.
