Kaizen is a lean manufacturing tool that improves quality, productivity, safety, and workplace culture. Kaizen focuses on applying small, daily changes that result in major improvements over time.
Kaizen first surfaced during the effort to rebuild Japan after World War II. At the time, several U.S. business consultants collaborated with Japanese companies to improve manufacturing. The collaboration resulted in the development of several new management techniques, one of which was Kaizen. Kaizen comes from two Japanese words: Kai (improvement) and Zen (good). Over time, it became widely known as “continuous improvement.”
Unlike many business practices, Kaizen’s strength comes from requiring all workers—from the CEO to the shop floor assistant—to participate by making suggestions to improve the business.
How Does Lean Kaizen Work?
Kaizen works by reducing waste (muda) and eliminating work processes that are overly difficult (muri). As a lean business practice, Kaizen succeeds when all employees look for areas to improve and provide suggestions based on their observations and experience.
From the beginning, it must be clear that all suggestions are welcome and that there will be no negative consequences for participating. Instead, employees are rewarded for changes that improve the workplace. Workers become more confident and invested in improving the company. They become leaders that continually look for areas that can be improved.
This is part 1 in our Kaizen educational series for businesses:
Start with training. Everybody needs to know that Kaizen is becoming part of the workplace culture.
Support Kaizen from the top. Employees need to know that they will get support when they need it.
Get ideas flowing. Use Kaizen boards, quality circles, and suggestion boxes. Employees need a way to communicate effectively.
Keep ideas coming. Let employees implement their own suggestions when possible. This will encourage participation.
Remove barriers. Kaizen boards are especially useful here. They allow workers to post ideas, track their progress, and see the benefits of each improvement.
This will help your Kaizen program gain momentum and help it succeed. Workers will gain a sense of ownership over their tasks and become more involved in every aspect of the business.
Supporting Kaizen with Other Lean Tools
Kaizen provides one simple principle: look at how things can be improved, improve them, and then improve them again and again. You can do this by using Plan-Do-Check-Act (PDCA), empowering workers to find problems, develop solutions and apply solutions in a continuous cycle.
In addition to PDCA, Kaizen can be supported by other lean tools. These lean tools generally fall under the Kaizen Umbrella and include:
Automation: Improve efficiency and make work easier through automation.
Kanban: Empower Kaizen by getting the inventory you need, when you need it.
5S: Support continuous improvement by improving organization, standardization, and safety.
TPM: Eliminate downtime and boost overall production through preventive maintenance and training.
Part of what makes Kaizen work is that it’s flexible. It can be supported using lean tools that best fit your needs. Discover how you can use 5S to support Kaizen with the Best Practice Guide to 5S by Graphic Products. Improve safety, quality, and increase profits.
Other benefits improve the overall culture of the company and increase employee retention:
