Here's an overdue report on a book put out this year by Adapative Path, a product experience strategy and design consulting firm. Their blog is a great source of info on ideas and approaches to innovative product development. This year they released the book Subject to Change: Creating Great Products and Services for an Uncertain World (O'Reilly). The book outlines the trend of using the customer experience to inform the entire product design and development process and reviews the associated attitudinal and cultural changes necessary to embrace this approach to new product development. Here's a quick overview of some of the book's main points from a few of the early chapters.
