The concept of improvement in the workplace began in the United States during World War II. It began as a program known as Training Within Industry Service, or TWI. It was based off of Charles Allen's four-point method. The four steps were Job Instruction, Job Methods, Job Relations, and Program Development.

  • Job Instruction: The concept was that experienced workers and supervisors would train new workers and keep watch over their work until it was of satisfactory quality.
  • Job Methods: Workers studied and evaluated every step in an industries process. They would question the viability of each and suggest improvements where applicable.
  • Job Relations: This was the idea that management should view employees as individuals rather than a single group.
  • Product Development: The development of an improvement program.
After the war, this was brought over to Japan. The process was refined, by Toyota in particular, and became what is known today as kaizen, meaning "continual improvement."


Adopted in 2007, RobotEx has used the concept of kaizen to improve time management. It has been kept a part of the program as a standing philosophy of improvement. With this process, RobotEx will be able to meet the needs of future enterprises.
