“Writing a book has been the most complex information architecture challenge of my life. The permutations in which you can sculpt, exclude, clarify and link information are staggering. No surprise then that we relied on our familiar design process, heading up the chain of goals, structure, content and surface. We appropriated the tools of our trade: personas, content analysis, user feedback and deep iteration—but it was trial and error that finally unearthed the process that worked for us.” (Cennydd Bowles)
