By: Mike Rother


Embark on a journey to understand Toyota’s secret to success with ‘Toyota Kata: Managing People for Improvement, Adaptiveness and Superior Results’ by Mike Rother. This book summary outlines the inner workings of Toyota’s management practices and the values driving their continuous improvement efforts. Learn about ‘kata’, Toyota’s twin set of procedural routines – Improvement Kata and Coaching Kata, which enables the company to maintain its upward progress. The book also sheds light on how traditional three-day workshops and value-stream mapping often fail to provide desired work-process results, offering a refresher on the company’s unique experiment-based process improvement approach.

The Secret behind Toyota’s Success

Toyota’s continuous success is attributed to its application of Toyota Kata, a set of procedural sequences called “patterns” or “routines,” helping the company achieve its desired results. The Kata has two parts: an “improvement kata” and a “coaching kata,” which are repeatable routines used to drive Toyota’s continuous improvement that helped it move from where it was to where it wanted to be. These hidden tools, routines, and management techniques have been driving Toyota’s success by keeping two things in alignment and helping it cross “unclear territory.”

Effective Methods for Process Improvement

The traditional process improvement tools like workshops, to-do lists, and value-stream mapping do not deliver the intended results. Toyota’s approach is to understand the process deeply and improve it from the basis of that knowledge. Pursuing a “single-factor experiment” will help change one aspect at a time and check the result to understand the process better. With single-factor experiments, it is easy to distinguish cause and effect, leading to a deeper knowledge and improvement of the process. To build new neural pathways, practice the desired behavior pattern, and track progress quickly by organizing workdays for speedy review cycles.

Toyota’s Improvement Kata Philosophy

Toyota’s approach to improvement involves making it a part of daily work rather than an add-on project. The company’s vision, or “true north,” is zero defects, 100% value added, one-piece flow, in sequence, on demand, and security for people. Toyota’s method of improvement and adaptation is systematic and a fundamental component of every task. One essential aspect of the improvement kata is teaching people a standardized, conscious ‘means’ for sensing the gist of situations and responding scientifically. Additionally, Toyota defines a “target condition” to help the workforce move the company from where it is now toward the vision. While the path of improvement is long, unclear, and unpredictable, the company’s philosophy involves keeping thoughts and actions in sync with dynamic, unpredictable conditions. Management’s expectations regarding improvement are often too low in many firms as improvement isn’t continuous. Toyota’s approach to process improvement makes production the same as improvement, and vice versa.

The Improvement Kata

The Improvement Kata is a guide to adjusting work approaches and behaviors through repetitive practice. It employs “target condition thinking,” “problem solving and adapting,” and “five questions” to aid in achieving goals.

Improving with Target Conditions

Toyota emphasizes the importance of a “target condition” as a specific description of how a process should operate, not just a general work target. Managers and leaders play a role in increasing the improvement capability of people rather than focusing solely on improvement. Implementing standardized work and improvement kata can help reach the target condition, with a time horizon of one to four weeks. Starting with small steps and moving quickly in improvement cycles is more effective than getting bogged down in lengthy discussions. The book highlights the significance of having a long-term vision to focus on consistent improvement.

Navigating the Gray Zone

The “gray zone” refers to the uncertain space between your current and target conditions. Toyota advises visualizing this path as a staircase and climbing it while focusing on reaching the target condition. Use the PDCA cycle to implement improvement along the way: Plan, Do, Check, Act. This cycle relies on experimentation, so avoid debates and instead test hypotheses with real-life experiments. Rejecting a hypothesis due to an experiment’s negative outcome is a milestone in your improvement project. To succeed in the Toyota style, adopt a problem-solving mode and focus on reaching your target condition. Remember, “problems are jewels.”
