The A3 Thinker's
Action Deck
71 cards to frame, analyze & eradicate problems systematically
Systematic Problem-Solving,
One Card at a Time
Based on Toyota's renowned A3 thinking methodology, the Action Deck guides teams through a structured 10-stage problem-solving sequence. Each card poses thought-provoking questions that sharpen your thinking and keep conversations focused on what matters.
Printed on casino-quality card stock and designed to fit in your pocket, the deck is built for the real world — whiteboard sessions, gemba walks, team retrospectives, and coaching conversations.
With hundreds of questions across 10 stages plus a dedicated mentoring section, the Action Deck gives you the scaffolding to tackle any problem with clarity and rigor.
