Andrew Johnson is a leadership advisor and author of Iron Sharpens Iron, where he explores how the operating systems of elite sport can help businesses build stronger accountability, execution, and performance cultures. Drawing from lessons in professional sport, particularly the NFL, Andrew translates concepts like scoreboard clarity, roster discipline, standards under pressure, and “tape review” into practical frameworks leaders can apply inside modern organisations. His work focuses on helping companies move from average to elite by creating cultures where accountability is visible, standards are consistent, and performance improves because there is nowhere to hide. As a podcast guest, Andrew brings a practical and thought-provoking perspective on leadership, competition, talent, and sustained high performance.
