资料:People differ greatly in their readiness to try new products. In each product area,there are“consumption pioneers”and early adopters. Other individuals adopt new products much later. After a slow start,an increasing number of people adopt the new product.
The five-adopter groups have different values. Innovators are venturesome-they try new ideas at risk. Early adopters are guided by respect-they are opinion leaders in their communities and adopt new ideas early but carefully. The early majority are deliberate-although they rarely are leaders,they adopt new ideas before the average person. The late majority skeptical-they adopt an innovation only after a majority of people have tried it. Finally,laggards are tradition bound-they are suspicious of changes and adopt the innovation only when it has become something of a tradition itself.
