The Coaching Kata is a structured routine of five questions a manager asks a learner every day to develop scientific, improvement-oriented thinking. Popularized by Mike Rother in his 2009 book Toyota Kata, it teaches the Improvement Kata through daily practice rather than by handing over answers.
Most managers, faced with a problem, do the natural thing: they solve it. They walk up, diagnose it, tell the operator what to do, and move on. It feels efficient and it quietly guarantees that nobody but the manager ever gets better at solving problems. The Coaching Kata is the deliberate opposite. It is a fixed set of questions a coach asks, in order, every day, that forces the learner to do the thinking, so that over months the learner builds the habit of scientific problem-solving. The coach develops people; the people develop the process. It is the behavioral engine underneath a real lean culture and one of the most practical tools in lean manufacturing.
What Is the Coaching Kata?
The Coaching Kata is a practice routine for managers, a repeated pattern of five questions used to guide a learner who is working through the Improvement Kata. The coach does not supply solutions. Instead, the questions steer the learner to define where they are trying to get to, see where they actually are, name the obstacle in the way, decide the next small experiment, and set a time to go and see what that experiment taught. Mike Rother, the researcher who named and codified these routines after studying how Toyota manages improvement, describes the Coaching Kata and the Improvement Kata as two interlocking practices: one is the learner's routine for improving, the other is the manager's routine for teaching it (Lean Enterprise Institute, The Five Coaching Kata Questions).
The word "kata" comes from martial arts, where it means a form you rehearse until it is second nature. That is the point: the five questions are practiced daily, often in short cycles at a board, until asking them, and thinking that way, becomes the manager's default instead of jumping to a fix. Repetition is not a side effect of the method; it is the method.
Why Ask Questions Instead of Giving Answers?
Because the goal is capability, not just a solved problem. When a manager hands over the answer, the problem gets fixed once and the operator learns nothing about how to fix the next one. When a manager asks the five questions instead, the operator does the reasoning, hits the obstacles, runs the experiment, and keeps the learning, so the next problem gets solved without the manager in the room. Over a plant, that is the whole difference between an organization where a handful of experts solve everything and one where improvement happens everywhere. It is slower on any single problem and far faster across a year. It also changes the manager's job description: from being the person with the answers to being the person who develops people who find answers, which is exactly the "respect for people" pillar in action. This is why the Coaching Kata pairs so naturally with a gemba walk where the questions are asked at the actual place the work happens.
What Are the Five Coaching Kata Questions?
The five questions are asked in order, in a short daily cycle, with the coach and learner standing at the learner's board. They map directly onto the Improvement Kata the learner is running.
- What is the target condition? The learner states the specific, measurable condition they are trying to reach by a near date, the near-term goal, not the far-off vision. This anchors the whole conversation to a concrete destination.
- What is the actual condition now? The learner describes where the process actually stands today, with real data and observation. On the back of this question sits a set of reflection prompts about the last experiment: What was your last step? What did you expect? What actually happened? What did you learn?
- What obstacles are preventing you from reaching the target condition, and which one are you addressing now? The learner names the obstacles found so far and picks the single one to work on next. This keeps the effort focused on one obstacle at a time instead of boiling the ocean.
- What is your next step? The learner defines the next single experiment to run against that obstacle, and states what they expect to happen. One step, one prediction, so the result actually teaches something.
- When can we go and see what we have learned from taking that step? The coach and learner set a specific time to review the result, which sets the cadence of the next cycle and makes the commitment real.
Notice what the questions never do: they never contain the coach's solution. Even when the coach can see the answer, the discipline is to keep asking, because the point is to grow the learner's thinking, not to be right fastest.
How Is the Coaching Kata Different From the Improvement Kata?
They are two halves of one system, run by two different people. The Improvement Kata is the learner's routine: understand the direction, grasp the current condition, set the next target condition, and experiment toward it. The Coaching Kata is the manager's routine for developing that skill in the learner, delivered through the five questions. One is about improving the process; the other is about improving the person who improves the process. You need both, because the Improvement Kata practiced without a coach tends to drift, learners skip the hard steps, jump to solutions, or quietly give up on obstacles, and the Coaching Kata gives it structure and accountability. The coach also needs their own coach, often called a second coach, who watches the coaching itself and develops the manager's questioning, so the capability cascades up the organization rather than depending on one gifted individual.
What Are the Most Common Coaching Kata Mistakes?
The routine looks simple, which is exactly why it is easy to do badly. The failures are predictable and every one is a habit the coach has to unlearn.
| Mistake | What it looks like | The fix |
|---|---|---|
| Coaching by answering | The "question" contains the solution: "Have you tried resetting the guide?" | Ask a real question and wait; let the learner reason |
| Vague target condition | "Improve quality" with no number or date | Insist on a measurable condition by a near date |
| Giant next step | The next step is a two-week project, not an experiment | Shrink it to one testable step with a prediction |
| No cadence | Coaching happens when there is time, which is never | Same time, every day, at the board |
| No second coach | Nobody develops the coach, so bad habits harden | Add a second coach to watch the coaching |
The deepest of these is the first. A coach who cannot stop supplying answers turns the five questions into a scripted way of leading the learner to the coach's solution, which teaches compliance, not thinking. The tell is that the learner keeps looking to the coach for approval after each answer. When coaching is working, the learner looks at the board and the process, not at the coach's face, because they are doing the reasoning themselves.
How Do You Start Practicing the Coaching Kata?
Start small and daily. Pick one process, one learner, and one challenge, set up a simple board showing the target condition, current condition, obstacles, and the experiment log, and hold a short coaching cycle every day, ideally at the same time. Keep the first cycles brief and expect them to feel awkward, because you are unlearning the reflex to give answers. Resist three temptations: solving the problem yourself, letting the target condition be vague, and letting a "next step" be a big project instead of a single testable experiment. Bring in a second coach as soon as you can, so someone is developing your coaching while you develop the learner. The habit takes months to groove, which is normal; this is a practice routine, not a course you complete. It connects upward through kaizen events and daily improvement, holds its gains through standard work and, done at scale, builds the shared problem-solving muscle that formal root cause analysis depends on. It also strengthens the same negotiated, bottom-up thinking behind the catchball process in strategy deployment. The catch is that coaching needs a visible current condition to coach against, which is hard when the data lives on paper and arrives late. That is the pattern Harmony deploys on running floors: standards, checks, and problem logs become live station-level capture, so the "actual condition now" a coach asks about is real and current, not a week old (live floor visibility).
