What is Kaikaku

The video discusses two approaches to improvement in lean manufacturing: Kaizen and Kaikaku.

  1. Kaizen focuses on continuous, small, gradual improvements in existing activities.
  2. Kaikaku (or Kaku) involves radical, sudden changes to transform entire work areas or production processes with the goal of significantly improving quality, productivity, and safety.

Kaikaku requires careful planning and clear communication with all employees involved as it can lead to significant cultural changes within the company. Techniques for implementing Kaikaku include the Single Minute Exchange of Die (SMED) to reduce machine setup times and organizing work into small, autonomous production cells to enhance efficiency and communication.

In summary, Kaikaku is a methodology for radical change, aiming to introduce new techniques and ways of working to achieve drastic improvements.
