Agile Pain Relief Consulting

Agile Glossary and Reference Library

World’s Largest Opinionated Agile Reference Library. The content is created and the links are curated through the lens of Agile Pain Relief Consulting’s view of what is effective in the practice of Scrum and Agile. We don’t accept submissions, and emails to that effect are marked as spam. Book listings may use affiliate links that could result in a small commission received by us if you purchase, but they do not affect the price at all. From experience, this won’t amount to anything more than a cup of coffee in a year.

We’re always looking for all things Agile. As a result, we’ve amassed a large collection of information covering lots of practical topics, techniques, tips, and case studies which we believe may help you toward your Scrum/Agile goals. They have been curated and organized into one spot, to share with you to help you on your Agile journey. We routinely scan for broken links, but if you spot one before we do, please let us know.
