What Is ShuHaRi?
The concept of ShuHaRi originates from the Japanese Noh-theater. It is a model practiced to illustrate the pathway a beginner requires to take from each moment someone expresses the interest to study something until that person becomes a master. Though this theory began from the world of theater, it became famous in martial arts. Numerous people still believe today that this is a martial arts technique.
+ The ShuHaRi principle describes the 3 main stages of learning.
Shu, ha, and ri are the various stages of learning. The belief is that each person who embarks the new learning journey will progress through these three stages to become an expert or master. These three terms refer to three stages of learning for the student and three levels of involvement for the teacher: shu means "to protect," ha means "to break away," and ri means "freedom to create."
Step 1 – Shu: to obey
In the shu phase, the student, under the watchful eye of the master, learns the fundamentals by repeatedly performing tasks to precise standards. At this stage, the student is observed by the teacher, who is, in a sense protecting him, and the work product, from failure.
Step 2 – Ha: To liberate oneself
In the ha stage, the student has more freedom to practice unsupervised, although the master checks on her; the student
can apply the rules creatively, but still follows the standard form quite rigidly.
Step 3 – Ri: Separate
In the ri stage, the rules and behaviors have become so ingrained that they no longer think about them consciously. The actions come naturally, and the student is then in a position to develop the understanding and to improve on what she has learned. This cycle continues throughout the individual's life. It is a learning cycle because the student is going through ShuHaRi over and over, more and deeply, periodically returning to the basics.
+ Implementing Lean Six Sigma with ShuHaRi
This simplistic but effectual concept can be seen in any learning context, whether in one's personal life or the workplace or implementing Lean Six Sigma. Embracing ShuHaRi will allow us to more efficiently drive change and adopt Lean Six Sigma techniques more effectively.
+ ShuHaRi applies as follows to the Lean Six Sigma projects :
For the first project: The project leader (Lean Six Sigma Master Black Belt), considered as the expert of the subject, is the single decision-maker of the operations to be performed. The whole team is then considered as protegés.
For the second project: The project leader (Lean Six Sigma Master Black Belt) intervenes only as an assistant and advises the Black Belt or Green Belt of the different projects.
For the subsequent projects: The expert is no longer in the projects and lets them manage the projects themselves. Black Belt / Green Belt, who become experts now, will carry forward the methods they wish to use. The expert is then available to answer problems, guarantee concrete results, and advise if essential.
+ Example from Toyota
The basic principles of Toyota learning can be traced to the teachings of Zen Buddhism, but they are not unique to Toyota. Toyota's teaching methods and the Japanese concept of kata are inline. The core of kata is the layered learning cycle, which is called in Japanese ShuHaRi. While it is easy to see how ShuHaRi applies to manual tasks like those on an assembly line, we might question how this approach works beyond the shop floor. However, at Toyota, ShuHaRi is the fundamental premise for all workers' training and development, including leaders.
To understand in detail, the conglomeration of ShuHaRi principles with Lean, refer to or listen to "The Toyota Way to Lean Leadership: Achieving and Sustaining Excellence through Leadership Development" (Book by Jeffrey Liker).
Can Six Sigma and ShuHaRi Coexist?
Many companies are using approaches like Six Sigma and ShuHaRi in their business. Strategies such as ShuHaRi and Six Sigma allow companies to contend the consumer market's pressures and demands and even outshine in their businesses. However, these two methodologies are different in their intentions and implementation. ShuHaRi and Six Sigma should be seen as parallel strategies. The answer is in getting the right balance between rigidity and adaptability. While ShuHaRi is unquestionably not a lazy approach, combining it with Six Sigma, uniquely for areas where process enhancement is the goal, can help bring a more structured framework to problem-solving, ideation, and process optimization.
ShuHaRi and Six Sigma are proven and tested to help companies to achieve better results. However, to successfully implement Six Sigma and ShuHaRi together, companies must not be focusing on the methodologies. Alternatively, teams need to look at the system as a combination and find how ShuHaRi and Six Sigma principles can effectively create a product or service that customers will enjoy.
