  • ✓ Use responses from users and stakeholders to prioritize features and tasks
  • ✓ Incorporate feedback into prototyping and experimentation
  • ✓ Building the good habits of a good software developer

Reliable and regular feedback is the core of successful software development.

In The Feedback-Driven Developer, you'll learn how to establish the kind of development process that helps you eliminate wasted time and ensure what you're delivering is working, reliable and most importantly, valuable.

About the book

The Feedback-Driven Developer distills veteran coder Ashley Davis's 30 years of experience into a comprehensive approach to creating a rapid, quality-focused development process.

This entertaining and personal book introduces dozens of practical techniques for using feedback throughout the dev lifecycle. You’ll see each idea demonstrated hands-on as you explore a full-stack web application. You'll learn how to plan for change, effectively refactor, set up and automate tests, and ship your software to production.

As you go, you’ll also explore refactoring into desktop and mobile versions of your applications, expanding the reach of your software. Once your software is in production, Ashley reveals how you can ensure it runs reliably with vital techniques for debugging and triaging problems in live systems.

"Ever wonder how the experts manage to develop high quality software at a rapid rate?..... Software development can be slow and difficult. What if you had a superpower to make it faster and easier?..... It's no secret, it's all about feedback, how to get it, and what to do with it. The Feedback Driven Developer does a great job of presenting a solid way of working through the guided development of an example web application."
