Is Google Developing a Culture of Testing?

In part two of this two-part episode on The DevOpsHandbook, Second Edition, Gene Kim speaks with coauthors Dr. Nicole Forsgren and Jez Humble about the past and current state of DevOps. Forsgren and Humble share with Kim their DevOps aha moments and what has been the most interesting thing they’ve learned since the book was released in 2016.

Jez discusses the architectural properties of the programming language PHP and what it has in common with ASP.NET. He also talks about the anguish he felt when Mike Nygard’s book, Release It!, was published while he was working on his book, Continuous Delivery.

Forsgren talks about how it feels to see the findings from the State of DevOps research so widely used and cited within the technology community. She explains the importance of finding the link between technology performance and organizational performance as well as what she's learned about the importance of culture and how it can make or break an organization.

Humble, Forsgren, and Kim each share their favorite case studies in The DevOps Handbook.
