Personas, an essential step to successful product development, are profiles of target customers created to focus development teams on user need, context, and pain points. The Persona Lifecycle , published by Morgan Kaufmann in 2007, is a comprehensive treatment of persona creation, use, and evaluation, complete with case studies, justifications, and methodology. The groundbreaking book has received 17 five-star reviews on Amazon and accolades from gurus in the field. While the book is a must-have for user experience practitioners, the industry has called for a shorter, quick-reference edition that features just the basic steps for creating and using personas. The Persona Lifecycle: Practitioners' Quick Reference is a low-priced, condensed version that borrows just the basic steps from the parent book and presents a how-to for students, those new to the field, and practitioners wanting a quick refresher while on the job.
