Darren is the Director and Leadership Coach at Making Lean Work Ltd and holds a master’s degree from the Lean Enterprise Research Centre at Cardiff University. He brings more than 25 years of experience helping leaders transform organizations in automotive, aerospace, medical devices, energy, and healthcare.

In this episode, Darren and Mark explore why so many Lean and continuous improvement programs fail to sustain—and how leaders can build the right systems and habits to make improvement last. Darren explains the three common pitfalls he’s seen across industries: choosing the wrong improvement approach, relying on traditional “solution thinking,” and lacking consistent leadership routines.

Darren also introduces his DAMI model—Define, Achieve, Maintain, Improve—as a way for organizations to avoid “kaizening chaos” and instead create a stable foundation for improvement. He shares stories from across sectors, including healthcare examples where better standards and daily management led to faster care, higher throughput, and dramatically lower mortality rates.

Mark and Darren discuss the difference between problem-solving and firefighting, the danger of “shiny Lean” initiatives that don’t address core issues, and the leadership routines that keep everyone aligned and focused on the right problems. The conversation offers a grounded reminder that Lean isn’t about tools or jargon—it’s about building consistency, clarity, and capability throughout the organization.

“You can’t kaizen chaos. First, you have to define and stabilize the standard.”

“Most organizations say they want improvement—but they haven’t built the routines to sustain it.”

“If every team in your business is working on the right problem, that’s an incredibly powerful organization.”

“Firefighting feels heroic, but it hides the real causes and keeps us from solving them.”
