My colleague Celine Pering just picked up this book by Kim Goodwin of Cooper, and it’s a stunner. A real tome at 700+ pages, it covers a huge swath of the design research and development process for complex digital products, with an unsurprising emphasis on Cooper’s persona process. It’s well organized, with a nice balance of theory and practical advice, and highly visual. For a comprehensive hands-on guide with lots of examples, this is the best I’ve yet seen. Kudos to Kim, this must have been a big undertaking.
