TESTIMONIES FROM PARTICIPANTS OF LEAN IMMERSION WEEK 2024

“Knowing cases from other companies, having close contact with people we didn’t know, that I didn’t know. This is extremely rich, extremely important.”

“Even with all my experience of over 14 years working with Lean, I learned new things from the senseis, like very specific nuances of Lean. I highly recommend it.”

“Learning from the senseis who worked at Toyota is amazing. In addition to networking and connecting with other people, I think it’s a great opportunity to truly immerse yourself. I highly recommend it.”

“I lived it, I experienced it, I had the opportunity and discussions. I can tell you: this immersion is real! It’s 7 months of learning in 7 days of immersion! It’s worth it!”

“Apparently complex topics are taught with a very simple and clear teaching method, accessible to anyone. We can see here that Lean is a philosophy for life and for living. I recommend it to anyone, in any position.”

“A unique opportunity to be with these Lean masters. We had many exchanges, and I leave here very enriched with knowledge, with my expectations exceeded. An experience I will carry for the rest of my life.”

“This immersion opened a new horizon for me, to go to the shop floor and better develop my work from now on. I feel more empowered to take on the challenge of building our area in a better way, in a leaner way. I invite everyone to take on this challenge.”

“My expectations for participating in this immersion were high, and now on the last day, I can say they have all been exceeded. The contact with the senseis, the exchange, the experience, all brought more knowledge to us. Truly a great event.”

“I learned that Lean is actually a way of life that I will carry not only into my professional life but also into my personal life. The great desire we have here is for everyone to have this experience. That’s why I highly recommend it.”

“I now understand why Toyota is what it is. The company’s president is here talking about what happens on the shop floor. For me, it was fantastic, emotional. I leave here a much more fulfilled person in terms of Lean. Thank you very much for the opportunity.”

“It was very important to participate in this immersion, and I leave here with a much broader view of Lean. It was far better than I had imagined, especially because of the program format, the group simulations, the visits, and the conversations with the consultants. The investment was definitely worth it.”

“This week with the senseis, who are the masters of Lean, surprised me in every way because we saw some of the theory at the foundation, but we also saw a lot of practical things, like the visits to companies here in the United States. I am extremely grateful. A unique opportunity. I recommend it to everyone who can come.”

For nearly three decades, Honsha has been implementing TPS/Lean across various industries globally, including Automotive, Food, Pharmaceutical, Manufacturing, Healthcare, Banking, Insurance, Government, and more. We focus on the purpose of TPS/Lean and the principles of Continuous Improvement and Respect before seeking ways to implement tools. This has allowed us to develop a strong and loyal customer base, as this is the foundation for our clients to become self-sufficient.
Honsha associates, as former members of the Toyota team, have been deeply exposed to Toyota’s culture and its DNA. Due to this unique background, our understanding goes beyond the Lean Manufacturing tools learned from books. At Honsha, everyone has worked, lived, and rooted their practices and modeling of TPS/Lean. Our clients always remind us that “we see things differently,” and that is our differentiator.
