Lean Made Simple

Ryan Tierney

Transforming Sperrin Metal

Ryan set out a clear, ambitious target – build the world’s best lean organization and make Ireland the standard-bearer for what manufacturing can achieve. One question drives everything at Sperrin Metal: “How Can I Improve This?” Simple. Relentless. Contagious.

Lean Leadership: Change Yourself First

Brian walked a 20-year batch-and-queue business from chaos to lean in 14 months – and he was honest about what that felt like from the inside. Three rules. No going backwards. And yes, he really did burn the binders in the parking lot and walk on stage blindfolded.

Beyond 2025

Be first inline

Gemba Summit 2025 was the beginning. What happened in that room at Titanic Belfast is already rippling outward into factories, government departments, hospitality businesses, and manufacturing floors across three continents.

The Summit will return in 2027, and we’ll be hosting some other tours, activities and meet-ups before then. We’re not announcing dates yet, but when we do, the people on this list hear first. Sign up to stay in the loop on speakers, dates, and early-access tickets.
