#170: Leadership Lessons from the Marine Corps with Tanner Wortham

What can Agile leaders learn from the Marines? In this episode, Tanner Wortham joins Brian to share how principles of military leadership—like building authority into the trenches, experimenting under pressure, and prioritizing shared mission over ego—map surprisingly well to modern Agile teams.

Overview

In this conversation, Brian sits down with Marine Corps veteran and Execution Architect Tanner Wortham to explore the parallels between leading Marines and leading Agile teams. Drawing from both military and coaching experience, Tanner unpacks how the Corps’ “rule of three,” mission-first mentality, and obsession with experimentation mirror the best of Agile thinking.

They discuss how effective leadership empowers decision-making at the edges, why conflict shouldn't be avoided but navigated with curiosity, and how facing toward hard problems—rather than away from them—builds high-performing, resilient teams. Whether you're coaching a Scrum team or leading large-scale transformations, Tanner’s insights offer a fresh lens on what it really means to lead with agility.
