Essential Skills for the Agile Developer

Essential Skills for the Agile Developer
A Guide to Better Programming and Design
Essential Skills for the Agile Developer

by Alan Shalloway, Scott L. Bain, Ken Pugh, and Amir Kolsky.

This book answers the question many developers have after taking some initial Agile/Scrum training – “OK, how do I write code now that we are building our software in iterations?” This book provides over a dozen proven practices that help developers improve their coding practices and make their code more easily changeable and maintainable in Agile projects. Please read the preface to better understand how to read this book.

Here's what Dean Leffingwell, creator of Scaled Agile Framework and author of Agile Software Requirements had to say about Essential Skills:

This book clearly meets the promise of the title, as it truly does describe the "essential skills that every agile developer should possess". With all the focus on agile software project management techniques like Scrum and Kanban these days, it’s refreshing to see that the folks at Net Objectives understand that no matter how we manage, or how we scale, it’s all for nought unless the developers and testers create better quality code at the origin. That’s what this book is about. It’s a short, understandable and essential read for every practitioner interested in improving the quality, agility, and maintainability of the code that ultimately, we all depend on.
