Jez Humble, a DevOps thought leader, discusses his book "Accelerate," co-authored with Nicole Forsgren and Gene Kim, which explores the intersection of Lean software development and DevOps to build high-performing technology organizations. The book is a culmination of years of research, including insights from the State of DevOps Report, and offers a comprehensive look at how technical practices, culture, product management, and leadership predict and enhance IT and organizational performance. Humble emphasizes that while tools and processes are important, real transformation requires cultural change and leadership support, which can be difficult within traditional organizational structures. He also highlights the importance of continuous improvement and the challenges of balancing day-to-day work with long-term development goals. Humble's approach to writing "Accelerate" involved using continuous integration tools like CircleCI, demonstrating a commitment to the practices he advocates. The book is aimed at a broad audience, providing both validation for experts and insights for newcomers into the scientific principles underpinning effective software delivery and organizational change.
