"I’m pleased to see Avi Parush publishing this book. He provides us with a well-thought out, well-illustrated analytical framework and methodology to bring to bear on a wide range of interface/interaction design and development problems. I personally have long believed and tried to practice the idea that interaction and interface architecture/design can and should be done separately from actual implementation during software development. An intertwined and intermingled focus on implementation, with implementation driving design thinking, often leads to premature choices that close off later opportunities created by having learned more about the user’s tasks and goals. The book provides us with a way of thinking about interface/interaction design and development that helps sort through the often confusing demands created by the need to do both, often iteratively. I think that both the experienced professional and the aspiring interaction designer will be able to find value in the framework and methodology described by Avi Parush. His work is grounded in both knowledge of cognition and in experience with actual design and development." --Thomas Hewett, Ph.D., Professor Emeritus of Psychology and of Computer Science, Department of Psychology, Drexel University
