Every information system brought into service in every type of organisation requires user acceptance testing. It is by far the most common activity carried out by non-IT specialists. This book is designed to be a hands-on manual for non-testing specialists to plan and carry out an effective acceptance test of an information system. It provides a structured and step-by-step approach to effective acceptance testing and identifies ways of making the process as simple and cost-effective as possible. "A UAT guide for users: that is a novel thought! This fills a gap in my bookshelf, a volume I wish I had years ago. It would have helped me to help the business. But more than that: it would have helped business users to help themselves, and see that UAT is more than just a necessary evil, but has clear purpose, methods, goals and skills. This is a step by step guide that is clear and praise worthy. You never know, it could be a recruiting arm for professional testers in the future, brought in from the business." Peter Morgan, Testing Practitioner.
