Guide to Kaizen methodology.If you are exploring ways to make your organization more efficient and better at sustaining continuous improvement, you may have come across references to the Kaizen Methodology. Masaaki Imai introduced the Kaizen Methodology to the world in 1986 in his book, Kaizen, The Key to Japan’s Competitive Success. We recommend it along with several other titles that we’ll share at the end of this post. This post provides you with the basics of the Kaizen Methodology and hopefully leaves you wanting to learn more.



What is Kaizen?

Masaaki Imai described Kaizen this way, “Kaizen is everyday improvement, everybody improvement, everywhere improvement.” The word Kaizen comes from the Japanese words for “Good” (zen) and “Change” (kai). In the workplace, Kaizen refers to activities that continually improve all functions and involve every employee from the executive team to project managers and front-line workers. Japanese automotive manufacturing businesses embraced the Kaizen method after World War II. It has been adopted by organizations in every sector worldwide.

The Principles of the Kaizen Methodology

Kaizen is not a prescription for business process improvement or quality control. Instead, it is a philosophy that informs every decision and permeates the culture. The Kaizen philosophy is the basis of many improvement methodologies including Six Sigma, Lean, Total Quality Management, and the Toyota Production System. The Kaizen Methodology rests on several core beliefs:

  • Every process can be improved
  • Continuous improvement is essential to competitiveness
  • Defects and errors are almost always the faults of flawed processes, not people
  • Every person in the organization must help implement improvements
  • Incremental changes can have a significant impact

The Benefits of a Culture of Kaizen

People often associate Kaizen methods with Lean manufacturing and its goal of waste reduction. That is an important benefit of the Kaizen methodology, but it is far from the only one. Others include:

  • Employees are more satisfied because they have a direct impact on how work gets done
  • Employees are more committed because they have more ownership over the processes they oversee
  • Employee retention improves because of the factors mentioned above
  • The organization is more competitive due to improved efficiency which leads to lower costs, higher quality, and more innovative products
  • Improved consumer satisfaction resulting from higher quality products with fewer faults
  • Better problem solving happens when people look at processes from a solutions point of view
  • More cross-functional collaboration occurs as people work together to solve problems

How to be an Influential Kaizen Coach


How to Spread the Kaizen Mindset

Engaged leadership is arguably the factor most relevant to the organization’s ability to spread the Kaizen method. Organizations with leaders who commit to providing the education and resources necessary to achieve continuous improvement get the most out of the approach and see sustained results. Here are some things leaders can do to help spread Kaizen:

  • Lead by example; visibly participate in improvement work with great enthusiasm
  • Remind people about the importance of the Kaizen methodology as often as possible
  • Frequently ask for ideas for improvement and react quickly to those ideas
  • Empower employees to act on opportunities for improvement without fear
  • Recognize ideas that produce a positive impact beyond the balance sheet
  • Focus on the importance of small, incremental improvement. Be clear that every improvement doesn’t need to be a project or an event.
  • Define and celebrate the impact of Kaizen

How Technology Supports the Kaizen Method

You don’t need technology to implement the Kaizen methodology, but it sure helps. Investing in a software platform to collect ideas for improvement, manage their implementation, report results, and broadcast success puts an organization in the best position to get value out of Kaizen. Modern solutions include digital huddle boards, alerts and notifications, configurable dashboards for each role, control charts, X-matrices, and more. Kaizen and improvement software is the perfect marriage of philosophy and structure.


Suggested Reading

As promised, here are a few recommended titles in addition to Kaizen, The Key to Japan’s Competitive Success.

  • Toyota Kata (2009) by Mike Rother — This book covers how Toyota manages continuous improvement along with human respect through making Kaizen an integral part of the culture.

We hope this post has you thinking more about how you can apply the Kaizen methodology to boost productivity, reduce waste, and delight customers and employees. We’ve seen it work in countless organizations and are sure it could have an impact on yours.
