The concept of user stories has its roots as one of the main tenets of Extreme
Programming. In simple terms, user stories represent an effective means of
gathering requirements from the customer (roughly akin to use cases). This
book describes user stories and demonstrates how they can be used to properly
plan, manage, and test software development projects. The book highlights
both successful and unsuccessful implementations of the concept, and provides
sets of questions and exercises that drive home its main points. After absorbing
the lessons in this book, readers will be able to introduce user stories in their
organizations as an effective means of determining precisely what is required of
a software application.
Thoroughly reviewed and eagerly anticipated by the agile community, User Stories Applied offers a requirements process that saves time, eliminates rework, and leads directly to better software.
The best way to build software that meets users' needs is to begin with "user stories": simple, clear, brief descriptions of functionality that will be valuable to real users. In User Stories Applied , Mike Cohn provides you with a front-to-back blueprint for writing these user stories and weaving them into your development lifecycle.
You'll learn what makes a great user story, and what makes a bad one. You'll discover practical ways to gather user stories, even when you can't speak with your users. Then, once you've compiled your user stories, Cohn shows how to organize them, prioritize them, and use them for planning, management, and testing.
