The Wrong Kata

Mike Rother

This document discusses the differences between a troubleshooting approach to continuous improvement versus a more systematic approach focused on striving towards target conditions. It argues that while troubleshooting is necessary to address abnormalities, it is not a sustainable approach on its own. A better approach is to establish a target condition and take iterative steps through testing to reach that condition. This involves understanding the current state and direction of improvement rather than just reacting to problems. Managers can help reinforce this mindset by asking employees about their targets and progress rather than just what problems they have addressed.

© Mike Rother & Bill Costantino TOYOTA KATA 2 HOW DO YOU CURRENTLY TRY TO IMPROVE? The following is intended to prompt reflection and discussion. We hope you find our observations and comments useful. We think itʼs possible that weʼve frequently relied on a mistaken idea -- a mistaken mindset -- as our way of continuously improving: Weʼve often thought of improvement as reacting to abnormalities and applying problem-solving steps to them. In many cases that alone is an unsustainable approach.
© Mike Rother & Bill Costantino TOYOTA KATA 3 ITʼS A COMMON APPROACH We call it “troubleshooting” 321 4 Action-Item List Implement Examples: • Respond to an abnormality • Current-state Value Stream Map only, and then going after the lightning bursts • Waste walks • Asking people / brainstorming: “What should we improve?” Prioritize Notice a problem, abnormality or opportunity
© Mike Rother & Bill Costantino TOYOTA KATA 4 BUT SUSTAINED COMPETITIVENESS TAKES BOTH TROUBLESHOOTING AND STRIVING They are two different activities and mindsets, and we seem to be relying too much on troubleshooting alone StrivingReacting & Troubleshooting The Workday
© Mike Rother & Bill Costantino TOYOTA KATA 5 WHATʼS HAPPENING WITH THE TROUBLESHOOTING APPROACH? The typical idea is to avoid; to try to get back to a more predictable state that we think we had. But thatʼs often an illusion and not reachable with troubleshooting alone Predictable Zone Learning Zone Current Knowledge Threshold Abnormality
© Mike Rother & Bill Costantino TOYOTA KATA 6 HEREʼS WHY Thereʼs no question that we have to respond to abnormalities in order to serve the customer. Troubleshooting gets practiced automatically, which may explain our widespread reliance on it. If an operator gets bad parts, a machine breaks down, etc., we have to respond. If we do a root-cause analysis on the abnormality itʼs even possible that an increment of improvement can be achieved. But the overall effect of chasing abnormalities is often a kind of oscillation, rather than progress. Why? Because many of those abnormalities are normal for the process as itʼs currently designed and operated. With the troubleshooting approach we may only be tinkering within the normal variation currently inherent in a process. Deming even suggested that 80-97% of process variation is systemic, common cause variation. u u
© Mike Rother & Bill Costantino TOYOTA KATA 7 HEREʼS WHY (continued) Examining each abnormality, looking for its cause and then adjusting something in order to solve the problem is not a good improvement approach when youʼre dealing with systemic problems. In order to improve in this situation the system itself must be understood and changed. Instead of only reacting to abnormalities we should also examine the current operating pattern of the process, define the next desired operating pattern and iteratively work toward that operating pattern. This is a more systematic approach to improvement. In the long run homeostasis is probably not even possible, due to entropy and competition. Youʼre either getting a little better or a little worse. u u u

The step-by-step discovery process between where you are and where you want to be next. What pattern do you want to have next? What is the current pattern of working? 321 4 Itʼs here that you discover what you need to work on Sometimes called Gap
© Mike Rother & Bill Costantino TOYOTA KATA 9 The team records and lists the types of breakdowns in a pareto chart, analyses the causes of the most common breakdowns and introduces countermeasures. The process seems to improve for a while, but many abnormalities return over time. The team concludes the machineʼs ʻpersonalityʼ requires a certain ʻknackʼ to keep it running. Maintenance personnel prides itself in being able to get the machine running again quickly. TROUBLESHOOTING - EXAMPLE An automated machine has frequent breakdowns
© Mike Rother & Bill Costantino TOYOTA KATA 10 Based on a diagram by Ralph Richter Action-item list with always the same persons tasked “Solved” problems return Process output varies a lot Process not understood in detail Exchange of opinions Prioritization is often done by dominant person Unstructured discussion Lack of data TYPICAL SITUATION BASED ON TROUBLESHOOTING Firefighting & little improvement. We often find this situation in daily tier meetings, for example.
© Mike Rother & Bill Costantino TOYOTA KATA 11 The team responds to abnormalities as necessary, but also identifies and focuses on the following work processes that are associated with operating the machine: - Machine tending (multiple machines) - Changeovers - Logistics (moving material in and out) - Maintenance The team carefully observes each of these work processes to sketch, measure and understand their current pattern of working. Based on their understanding of the current operating patterns the team develops a next desired operating pattern for each work process -- called a target condition -- to be reached in 30 days. The team predicts that bringing the work processes into these desired operating patterns will reduce the amount of machine breakdowns by 80%. The team then works iteratively with PDCA to move toward the target conditions. The team learns as it strives to reach the target conditions and adapts based on what itʼs learning. SYSTEMATIC IMPROVEMENT - EXAMPLE An automated machine has frequent breakdowns
© Mike Rother & Bill Costantino TOYOTA KATA 12 WHATʼS HAPPENING WITH THE SYSTEMATIC APPROACH? The idea here is to systematically, scientifically navigate a learning zone to reach (strive toward) a new pattern of operation and level of performance Predictable Zone Learning Zone Next Target Condition Current Knowledge Threshold Where we want to be next Unlike troubleshooting, this is typically a deliberately learned skill or habit
© Mike Rother & Bill Costantino TOYOTA KATA 13 NOTICE THE DIFFERENT MINDSET Striving for a target pattern Reacting to abnormalities Troubleshooting Improving Whatʼs my problem, and how do I solve it? Where are we going next, and how do we get there?
© Mike Rother & Bill Costantino TOYOTA KATA 14 TROUBLESHOOTING IS NECESSARY, BUT ITʼS THE WRONG APPROACH FOR CONTINUOUS IMPROVEMENT, ADAPTATION AND INNOVATION THE POINT WEʼD LIKE TO MAKE...
© Mike Rother & Bill Costantino TOYOTA KATA 15 ONE WAY TO DEPICT IT? Current Standard Abnormalities (oscillating) Next Target Condition / Standard Troubleshooting Improvement A standard canʼt be reached 100% Doesnʼt have to be a big leap ** *********** * When we move from Troubleshooting into Improvement thereʼs a shift in our pattern of thinking and acting, characterized by striving (focused aspiration) instead of just trying to avoid or get back to something.
© Mike Rother & Bill Costantino TOYOTA KATA 16 HOW DOES AN EXPERIENCED IMPROVER THINK? Itʼs difficult to research, depict and convey because it becomes a mental habit Sense of direction or challenge Grasp the current condition Establish the target conditionInsert any problem or objective PDCA Letʼs-test-it orientation
© Mike Rother & Bill Costantino TOYOTA KATA 17 We think a good improverʼs fundamental pattern of thinking stays basically the same regardless of what theyʼre working on, big or small. They approach things a certain way. This makes some sense, since neuroscience tells us we canʼt switch our subconscious habits easily or quickly. PICK A GOOD IMPROVEMENT PATTERN TO PRACTICE Because it may become your habit As a beginner, practice on something small so you can focus on picking up the pattern youʼre trying to internalize. As your proficiency increases youʼll apply the pattern to any issue.
© Mike Rother & Bill Costantino TOYOTA KATA 18 IF YOU WANT TO GO BEYOND TROUBLESHOOTING Youʼll need to deliberately practice a different behavior pattern Thatʼs what the Improvement Kata is
© Mike Rother & Bill Costantino TOYOTA KATA 19 MANAGER THINKING & BEHAVIOR IS IMPORTANT Sometimes you hear a manager asking, “What have you improved since we last met?” When managers make statements like this they teach and reinforce the mindset and behavior of random improvement and troubleshooting. But improvement, adaptation and innovation involve purpose-oriented behavior, and managers can practice asking this more constructive series of 5 questions: • What are you trying to achieve? • Where are you now? • Whatʼs currently in your way? • Whatʼs your next step, and what do you expect? • When can we see what weʼve learned from that step?
© Mike Rother & Bill Costantino TOYOTA KATA 20 Next Target Condition Current Condition Gap = “Problem” Note: THE GAP IS NOT A “PROBLEM” We should stop referring to the gap between a current condition and a target condition as a “problem.” There are lots of problems/obstacles between here and there! Calling this gap a problem leads us to think of planning and implementing a solution, as opposed to working iteratively. We leap ahead with faith in our plan and fail to leave enough room for learning and adaptiveness.
© Mike Rother & Bill Costantino TOYOTA KATA 21 Obstacle or Problem PROPOSAL FOR BETTER TERMINOLOGY u A target condition is a new pattern youʼre striving to reach by a specified date, on the way to a larger overall challenge. A target condition lies outside your threshold of knowledge. You donʼt know exactly how youʼll reach it. u What you do to overcome an obstacle or problem on the way to the target condition are called steps, experiments or PDCA cycles. It almost always takes more than one step to break through an obstacle. Once you overcome an obstacle it means youʼve developed a solution to that problem. u Ingenuity, adaptiveness and innovation happen on the way; as you work step-by-step toward the target condition & act based on what youʼre learning. Next Target Condition Current Condition Steps Experiments PDCA Cycles Challenge Threshold of Knowledge
© Mike Rother & Bill Costantino TOYOTA KATA 22 FOCUSED ASPIRATION What managers should think about, for their organization to achieve continuous improvement and sustained competitiveness Whatʼs this teamʼs target condition? How does it tie into an overall challenge? By what means should the team be working toward the target condition?
© Mike Rother & Bill Costantino TOYOTA KATA 23 ALTERNATE DEPICTION by Emiel van Est
© Mike Rother & Bill Costantino TOYOTA KATA 24 A MESSAGE OF REFORM The more competitive the environment, the more your organization may need entrepreneurial thinking and acting A community of more effective Lean and managerial practice is growing, based on teaching & practicing the Improvement Kata in daily work. Alignment of actions across the organization increases when people work on the things that *need* to be done in service of a challenge and target conditions. This is a change from the approach to improvement whereby organizations just react to problems or address all the things they *can* improve in the pursuit of general waste elimination. What habits are the managers in your organization teaching?

Judging (what we typically do), is listening to an argument and then leading with what we disagree with or don't like about the argument. Joining, is listening to the argument, then trying to build off it. I was trying to reflect on the title of this SlideShare and why it evoked the judging reaction. What I came up with was there is nothing wrong with the troubleshooting kata it's just a "Necessary but insufficient for continuous improvement" kata. You still need it, it's just not going to get you 'continuous improvement' by itself. What if the message could be recast as "the troubleshooting kata by itself is not sufficient.” You need both but the ratio of effort by which you do them has to change over time towards continuous improvement. The way you achieve this is by emphasizing the Improvement Kata deliberately and resorting to troubleshooting only as needed. Do this for long enough and the need for the troubleshooting kata should decrease significantly.
