In the design community “time” is rapidly replacing “space” as the key to success. A person’s age is now usually a greater determinant of design requirements than the place where she or he lives. Further, the response times of products, systems or services are now a greater determinant of success than most other characteristics.
John Tomlinson’s thought provoking text provides an introduction to these matters via a thorough historical review and a careful elaboration of the concept of “immediacy”. The book is a “must read” for today’s designers.
