Kaizen is a process for continuous improvement.

Literally “good change”. Kaizen was developed between the United States and Japan throughout the 20th century. It is a form of continuous improvement following 6 steps:rD4

  1. Identify a problem or opportunity.
  2. Analyze the process.
  3. Develop an optimal solution.
  4. Implement the solution.
  5. Study the results and adjust.
  6. Standardize the solution.

The spirit of Kaizen can be summarized as “waste is a crime”—in the face of major constraints, misusing resources can be immoral.
