In this episode of Lean 9 1 1, Mark DeLuzio discusses the pitfalls of Kaizen, the second part of a three-part series on the subject. He highlights the importance of avoiding these pitfalls, whether you are new to Kaizen or have experience in its implementation. The first pitfall he addresses is the presence of observers in the Kaizen event. Mark firmly believes that there should be no observers and that everyone should be actively involved in the team. He emphasizes the value of learning by doing and compares it to watching golf videos without practicing the sport oneself. Mark also stresses the significance of keeping the team together throughout the Kaizen event and being fully dedicated to the process. He discourages part-time participation and emphasizes the need for punctuality and commitment to the team.
