Robertson’s Consumer adoption method

• Problem perception—the time when a consumer recognizes a need for change.

• Awareness—the stage at which the consumer becomes aware of the innovation.

• Comprehension—the learning period during which the consumer explores the characteristics and function of the innovation.

• Attitude formation—the result of a period of evaluating the innovation.

Legitimation—an optional stage during which the consumer seeks additional information about the innovation.

• Trial—the stage of trying on or experimenting with the innovation.

• Adoption—the ownership stage.

Dissonance—a stage that occurs only when the consumer questions the adoption decision and seeks reassurance.
