Credit. We believe that acknowledging credit and precedent are vital to the free flow and development of good ideas and sound practices. We always try to cite sources and grant credit for ideas and inspiration. That's why you'll find extensive reference lists in most of our publications. In turn, we appreciate being credited and referenced wherever credit is due.
 

Novelty. Usage-centered design did not spring from a vacuum, but we did coin the phrase "usage-centered design," developed many of its core concepts and techniques, and pioneered its practice. In case any one asks, yes, we invented essential use cases and believe we were the first to publish the idea of abstraction and intention as keys to better use cases. (See the bibliography on use cases.)
