Kata is a method of making small, incremental change toward improvements every day. Originating in martial arts, Kata are structured routines consisting of patterns. Practicing kata (patterns) consistently and deliberately forms a habit. Forming a habit develops new skills. With new skills comes increased confidence in one's abilities to recognize and make small improvements that keep a person (or a process) in top form continuously.
As simple as it sounds, Kata involves deliberate, repetitive practice to master. In martial arts, kata is choreographed patterns of movement that are practiced until mastery of a single form is achieved. The practice is applied again and again to learn and eventually master each small set of movements.
In manufacturing, kata describes the true continuous improvement philosophy and culture exemplified by Toyota. By implementing Kata, your organization can develop the habit and skills to shift individual mindsets and the corporate culture toward truly continuous improvement that keeps processes efficient, customers happy, and companies profitable.
“Toyota Kata” is the term that Mike Rother (internationally recognized Lean guru and author of Learning to See) coined to help American manufacturers mirror Toyota’s successful practices of true continuous improvement.
"Through the adjustment of what is learned along the way, Toyota advances as a scientist would. With each new empirical observation, the scientist adjusts the course to take advantage of what he has learned. I learn every day what I need to know to do tomorrow's work." ~Mike Rother from the book Toyota Kata: Managing People for Improvement, Adaptiveness and Superior Results
Past observations of Toyota’s operations educated American manufacturers on the innovative company’s methods for improving process efficiency and eliminating waste (the traditional “Lean Tools”). Decades later, however, the same observers were shocked that when they observed the same Toyota operations, they now saw different solutions to the same processes. Rather than implementing a one-time “Lean Tool” solution, Toyota had continued to adapt, improving their processes over time.
This culture of true continuous improvement is what keeps Toyota at the forefront of manufacturing excellence. Kata enables improving every process every day. It’s not limited to management or customer-facing employees. Every employee from top management to janitors is expected to encourage daily improvements through their own actions. Practicing kata will develop a habit that, over time, changes behavior, which ultimately changes culture.
Anyone who wants to develop the habit and skills of continuously improving daily actions can use Kata. Various manufacturing industries utilize the Kata methodology. Although Toyota Kata was developed to emulate Toyota’s Manufacturing culture, like the Lean Tools, it easily adapts to non-manufacturing industries. The Healthcare industry quickly embraced and has advanced using the Kata methodology. Agile Software Development can also use Kata for Agile Retrospectives. The opportunity exists to deploy Kata for startup businesses to drive progress and accountability.
Kata is a methodology that, with proper training and practice, will develop the habit, the skills, and eventually the culture/mindset of continuous improvement. As such, Kata can work on any service, any sport, and any process.
Kata is not something that can just be implemented. It’s a structured foundation of changing behavior that requires training and practice to ensure success. Because of the broad range of support and resources needed for implementation, Lean programs are typically started with the help of an outside catalyst (consultant) guiding the organization down the correct path. Similarly, guidance from an experienced Kata Coach is highly recommended to train the first rounds of deployment with a core team who will become the Advanced Kata Team for the site. With proper training, guidance, and practice, this Advanced Kata Team will develop into the future Kata Coaches that will coach and encourage the Kata culture throughout the organization.
“Lean” is made up of continuous improvement tools such as Value Stream Mapping, 5S, TPM, Standard Work, Kanban, and so on. Kata is a methodology rather than a tool. It is developing the habit and skills of making small, incremental changes regularly. As we implement the Improvement Kata (IK), an identified solution could be deploying an appropriate Lean Tools when needed.
The Kata methodology consists of the Improvement Kata (IK) and the Coaching Kata (CK). The Kata is carried out by a Learner and a Coach. Each Learner has a structured Storyboard to encourage dialog between the Leaner and the Coach.
Improvement Kata is a four-step model of scientific method of thinking. Improvement Kata is carried out by the Learner (mentee) who will conduct experiments to develop solutions.
The Four Steps of Improvement Kata
Coaching Kata is coaching the problem solving of the Improvement Kata (IK) to ensure the Learner is following the scientific method during the Improvement Kata process. The person who carries out this role is called the Coach (mentor). The Coaching Kata is comprised of five questions meant to guide improvements towards the target condition.

Try Starter Kata: Starter Kata are structured routines that you practice deliberately, especially at the beginning, so their pattern becomes a habit and leaves you with new abilities. Your first implementation of Improvement Kata can be your "Starter Kata" routine that will help your team learn fundamental skills.
Practicing Starter Kata increases the speed of learning and is particularly helpful when you want to create a shared way of thinking and acting in a group of people, because everyone starts with the same basics.
