In this book, you’ll: • Get an overview of scrum fundamentals for web and mobile projects • Become familiar with scrum’s roles: scrum master, product owner, team members, and interested observers • Understand scrum’s rituals: sprint planning meetings, daily standups, work process, demos, and sprint retrospectives • Gain a thorough understanding of the tools used in scrum: burndown charts, story cards, sprint backlogs, product backlogs, and more • Troubleshoot typical scrum issues • Discover how to effectively put scrum to work in your team SUPERCHARGE YOUR TEAM’S EFFICIENCY WITH SCRUM YOUR AUTHOR M.

Preface If you haven't heard about scrum, and you work in web or mobile development, it's time you did. Scrum is a way of organizing engineering teams around time-tested techniques to improve communication, increase the flexibility of the product devel- opment process, support constant improvement, and provide a sustainable rhythm for productivity with less pain and more participation. Scrum offers a core set of operating principles, and supports incredible flexibility for a team to adapt the process to their particular needs. Properly applied, scrum insulates engineers against interruptions and micromanagement while giving product managers the flexibility to adapt to market changes regularly, and the ability to predict how much work the team can take on and complete. In this book, you will be introduced to the fundamentals of scrum, and given ex- amples that you can apply immediately. And since scrum is as much about the people as it is about the processes, we will introduce you to a typical web and mobile development team, and show you the impact of scrum on their jobs, their working relationships, and the things they care about most in their professions. Whether you're not sure what scrum is, or you think your scrum process isn't all that it should be, this book can help. Scrum isn't magic, but the results it can produce are well worth taking the time to learn how to apply it effectively. Who Should Read This Book This book is for anyone who works in a team to build web or mobile apps: engineers, QA, management, designers, and product managers. It assumes no familiarity with scrum or other project management techniques. While it's aimed at readers who have little understanding of scrum, it will also be useful to those who are currently using scrum, but aren't sure that they're getting the results that they want from it.
