Most design research is ineffective because it isn't asking or answering the right questions.  Just Enough Research is here to help.  Whether you're just starting out in your design career, in the middle of a whole mess of product decisions, or trying to help your colleagues get over their fear of admitting ignorance, there is something in this book for you.  Just Enough Research has remained a popular handbook for over a decade, outlasting several technology hype cycles. It's brief. It's practical. It's got jokes.  Read this book. You will experience delight.
