Gästartikel av Jeff Liker och Tyson Ortiz: Kata Practice for Scientific-Thinking Skill and Mindset

Rikard Sjöström


Jeff Liker

Dr. Jeffrey Liker is Professor of Industrial and Operations Engineering at the University of Michigan and author of the international best-seller, The Toyota Way.

I dagens Lean Learnings har vi för första gången gästskribenter. Det är en spännande artikel som visar hur Jeff Liker – författare till The Toyota Way och nestor i lean-världen fortsätter att utveckla sitt synsätt om omvärderar sin tidigare forskning kring lean.

Vi tycker att det är positivt och lärande med utveckling, nya infallsvinklar och att personer inte sitter fast i beskrivningsmodeller eller koncept. Det är inte att modeller och koncept är fel (till exempel de 14 managementprinciperna), men de måste leva och utvecklas.

Kata som Jeff pratar om har även påverkat oss i vårt arbete som konsulter, i vårt arbete med träningar och inte minst i vårt arbete med oss själva. Att ständigt tänka i termer av att ”experimentera och lära” är nyttigt. Här ger kata oss en bra och pålitlig ledstång att följa. Läs, lär och reflektera!

The Toyota Kata practice routines help any organization increase its capability to pursue challenging goals.

The field of Lean has evolved significantly in recent years, and many organizations are changing the way they think about Lean. Historically a company’s Lean initiative has been the purview of improvement experts, traveling about the company leading projects to fix struggling processes.

After more than two decades of Lean initiatives in the manufacturing industry, the results have been somewhat underwhelming. Typically a company’s Lean initiative generates impressive initial gains, but with time then the improvements fade away and the organization does not gain a long-term competitive advantage.

In contrast, at Toyota is it the management hierarchy that is responsible for improvement, with only a small number of experts traveling about to coach leaders at all levels.

Toyota Kata begins with this assumption and further asks: What are the practice routines that will help managers outside Toyota develop the necessary skills and mindset to lead fundamental change in their organizations?

The core mindset is well captured in the scientific method often associated with Dr. Edwards Deming—the Plan-Do-Check-Action (PDCA) cycle. In this model, the plan starts with an understanding of the gap between where we are and where we want to be, ideas for getting us closer to our vision are like scientific hypotheses which must be tested (Do), and through Checking what happened we have an opportunity to learn and define further Action.

Kata are routines that a learner practices to develop skill, usually under the corrective guidance of an experienced coach.

The well-known movie The Karate Kid contains famous examples: “wax on, wax off. Paint the fence. Sand the floor.” Mr. Miyagi guided Daniel through practice of these simple routines in order to help his student learn karate.

Mr. Miyagi’s backyard improved dramatically as Daniel practiced his kata, but home improvement was not the point. Making Daniel into an expert fence painter or master car washer was not the point either. These kata were simply means to an end, growing in Daniel subconscious neural pathways and muscle memory enabling him to better defend himself.

Similarly the Improvement Kata is a routine to practice, a means to an end, not a tool to be mastered in itself. And although the learner practicing the Improvement Kata is focused on pursuing a challenging objective, reaching that objective is actually not the endpoint of the kata either! It is the beginning. Progress toward the objective is an expected outcome, but a coach is present to modify the practice as necessary in pursuit of the true purpose: helping the learner grow a scientific mindset that enables them to comfortably and competently face, and meet, increasingly difficult challenges.

Toyota Kata explicitly puts the process owner in the role of scientific problem solver, and acknowledges that they may initially lack the ability to be successful. It is about cultivating the requisite skills and mindset through deliberate practice.

In a sense Toyota Kata reverses earlier approaches to Lean, a field that contains countless books, articles, and courses describing what Lean thinking is or what a Lean process looks like. Such resources implicitly leave an organization implementing Lean to figure out how to achieve and sustain these objectives, and history is demonstrating that existing organizational cultures are largely in conflict with those principles and concepts.

Experience suggests that discussion and education, tools and principles, are insufficient to drive sustainable change.

Instead Toyota Kata focuses on how to begin developing the desired culture, offering specific practice routines to help an organization start deliberately cultivating within employees the skills and mindset needed to sustainably pursue the traditional objectives of Lean — or any other objective for that matter.

There is a playbook for the meta skills that help you reach your own challenging goals, and it’s the Improvement Kata.
