Title: Thinking about technology
Description: We apply a cognitive lens to understanding technology trajectories across the life cycle. We develop a coevolutionary model of technological frames and technical change to explain sources of variation in the era of ferment, conditions under which a dominant design is achieved, the underlying architecture of the era of incremental change and the dynamics associated with discontinuities. We show that interactions of producers, users and institutions shape the development of collective frames around the meaning of new technologies.
