Trained by disciples of the Toyota Production System, Tim has held leadership positions in operations management, Lean, and quality across innovative high-tech manufacturing companies and has worked across industries including aerospace and defense, automotive, electronics, medical devices, oil and gas, and nuclear power. He also worked in a Shingo Prize-winning facility.
Tim is the founder and principal contributor of A Lean Journey, a long-running resource dedicated to sharing practical lessons in Lean thinking, continuous improvement, problem solving, and leadership. Through the blog, Tim has published thousands of Lean Tips, articles, interviews, Lean Roundups, and educational resources designed to help practitioners and leaders apply Lean thinking in the real world.
Tim is also an author and published contributor. He co-authored The Lean Handbook: A Guide to the Bronze Certification Body of Knowledge (ASQ Quality Press), a comprehensive reference covering the Lean certification Body of Knowledge developed by SME, AME, ASQ, and the Shingo Institute. His articles have also appeared in Quality Magazine, AME, and ASQ publications, covering topics such as Lean leadership, Kaizen, value-stream mapping, standardized work, Lean daily management, strategy deployment, and the application of quality thinking to emerging technologies. His recent work has explored the relationship between Lean, quality, and artificial intelligence.
As an educator and speaker, Tim has presented at Lean and manufacturing conferences and has delivered webinars and educational sessions on topics including Lean infrastructure, value-stream mapping, metrics, Kaizen, employee engagement, and practical Lean implementation. His conference presentations include sessions at the Northeast Lean Conference, where he has shared both practical Lean methods and lessons from real-world transformation efforts.
Tim has also contributed extensively to the Lean and quality communities. He is a member of the American Society for Quality (ASQ) and participated in the ASQ Influential Voices program. He has served on the Board of Directors of the Association for Manufacturing Excellence (AME) Northeast Region, including as Northeast Director, and continues to contribute to the Lean manufacturing community through AME activities.
Tim holds a Lean Certification and Six Sigma Black Belt from Central Connecticut State University, a Lean Bronze Certification from the Society of Manufacturing Engineers, a Master Lean Six Sigma Black Belt from the Management and Strategy Institute, and is a Shingo Institute Alumni.
His philosophy is simple: Lean is not just a collection of tools—it is a way of thinking, learning, and engaging people to continuously improve the way work gets done.
A short conversation on how Tim found Lean, and what still fuels the pursuit of it.
I am the founder and contributor of A Lean Journey Blog — a site dedicated to sharing lessons and experiences along the Lean Journey in the quest for True North. Since I believe you should practice what you preach, my day job is a Lean practitioner leading continuous improvement efforts for OFS, a high-tech manufacturer of fiber optic cables and assemblies with several plants in the Northeast. A major focus right now is teaching problem-solving skills, Lean countermeasures, and how to see opportunities for improvement by actively learning, thinking, and engaging our workforce.
I've also supported the AME Northeast Region Board of Directors as the Social Media Lead, helping identify how to best leverage tools like LinkedIn, Twitter, SlideShare, YouTube, and Facebook to grow networking within AME's Northeast Region.
After coming from a research and development role into an operations role, I discovered Lean. In 1999 I started learning what Lean manufacturing was all about, and I have been learning about it ever since. In the beginning, Lean was a way to meet operational objectives; now I've found it's a profound way of thinking that encompasses everything I do — the best business performance system I've seen. My passion is fueled by those wonderful "a-ha" moments, when hours of study and thought finally fall into place, and by the people I've met going down a similar journey of their own.
Murphy's Law states that anything that can go wrong will go wrong — there isn't an organization that doesn't face problems. For me, the most powerful aspect of Lean is being able to solve those problems scientifically: the four-step PDCA cycle popularized by Dr. Deming. My engineering background built a foundation of hypothesis, experiment, and evaluation, so this feels natural. Nearly all of Lean's thinking processes are rooted in this same problem-solving process.
"Having no problems is the biggest problem of all." — Shigeo Shingo
Most people who try Lean in their organization fail to fully understand the people side of it. Lean, commonly known by its origin as TPS, is really the "Thinking People System" to me — learning to see waste and solve problems through the development of people, not tools. As in the namesake of my blog, "A Lean Journey — The Quest for True North," Lean is not about the destination but the direction you take toward it. It's not something you check off a to-do list; it's the constant, persistent pursuit of improving your current situation, which brings you to the next current state, and so on. Waste is all around us, yet many can't recognize it — activity does not equal productivity. The real challenge is to break the status quo and learn to truly "see": observing the actual condition, at the actual place, at the actual time.
"Lean is 90% people and 10% tools." — Bruce Hamilton, President, GBMP
The biggest opportunity is in our service industries. Lean has a proven track record across manufacturing, but we all encounter poor service, higher costs, and more waiting every day when we interact with businesses. Lean Healthcare has been a dominant theme for years, with strong examples to point to. Lean Government is moving forward too, with an early start from the EPA and legislation such as Connecticut's effort to use Lean techniques in state government. Lean focuses on process, has a measurable impact on time, capacity, and customer satisfaction, and involves every employee — a formula that can help many more organizations succeed.
