#171: Why Agile Teams Succeed—or Don’t with Colin Fisher

Most teams aren’t broken because of individual incompetence. They’re struggling because the group itself isn’t set up to thrive. In this episode, author and researcher Colin Fisher joins Brian to reframe how we think about team performance, conflict, and psychological safety through the lens of real science, real practice, and a little jazz. Overview Group dynamics aren’t fluff. They’re the operating system behind every Agile team’s success (or struggle). Colin Fisher, author of The Collective Edge, joins Brian to share what decades of research and hands-on observation reveal about high-performing teams. From ideal team size (spoiler: it’s 4.5), to avoiding the trap of blaming individuals for systemic issues, Colin offers a practical, thought-provoking look at how to build more resilient, collaborative, and human-centered teams. Expect fresh insights on team launch moments, role clarity, feedback culture, remote collaboration and how to keep your team “groupy” in the best possible way.
