In this solo episode, Hilary Corna challenges a common misconception in continuous improvement: doing “Lean” activities won’t automatically produce Toyota-level performance. She explains why many organizations copy the visible symptoms of Lean (boards, workshops, language) instead of building the system behind it—Toyota’s management architecture. Hilary breaks down what “architecture” really means in day-to-day leadership, why structure always wins over tools, how Lean becomes performative when the system isn’t designed for it, and the key questions leaders can ask to rebuild an environment where improvement becomes inevitable and sustainable.
