Your opportunities on the Web are vast, but so are the difficulties of delivering a site that customers will give high marks for content, ease of use, performance, trustworthiness, and overall satisfaction. These problems are not insurmountable if you solve them with the set of principles, processes, and patterns we have described.
In the rest of this book you will find more reasons to implement customer-centered design, descriptions of techniques to use in your current projects, and dozens of design patterns proven to enhance your customers' experience. Guidelines for instituting customer-centered design will help you through the process.
This book is meant as the first step in an ongoing conversation to improve the Web. We have not identified all of the useful Web design patterns. New patterns will be found, and the patterns we describe here will evolve as new techniques are invented and customer knowledge and skills change. We encourage you to join in the conversation and keep moving the Web toward the new, raised bar for success.
