Improvement Kata (Toyota)

The Improvement Kata is a structured four-step method that guides teams in the continuous improvement of their processes. Inspired by Toyota, it encourages a scientific approach to identify obstacles and experiment with solutions. This serious game allows participants to experience this process in a playful and collaborative manner.

Walkthrough

1. 1

   Introduction to the Kata

   15 min

   The facilitator presents the concept of the Improvement Kata and its four steps: understand the direction, assess the current situation, define the target, and experiment to overcome obstacles. They explain the importance of continuous improvement and scientific thinking. Participants are invited to ask questions to clarify the framework.

   Tip — Use concrete examples from your organisation to illustrate each step and make the presentation more relevant.

2. 2

   Understanding the Direction

   10 min

   Participants reflect on the vision or strategic objectives of their team or organisation. The facilitator asks: "What direction do we want to go in?" Participants discuss in small groups and share their thoughts with the larger group.

   Tip — Encourage participants to think long-term and to use inspiring yet realistic goals.

3. 3

   Assessing the Current Situation

   15 min

   Each group describes its current situation in relation to the defined objective. The facilitator guides participants with questions such as: "Where are we today?" and "What are the current obstacles?" Groups note their observations on post-its.

   Tip — Help groups to be specific and factual in their assessment to avoid generalisations.

4. 4

   Defining the Target

   10 min

   Participants define a short-term target that brings them closer to their vision. The facilitator explains: "The target should be a small, achievable step within a short timeframe." Groups share their targets and receive constructive feedback.

   Tip — Encourage participants to formulate SMART targets (Specific, Measurable, Achievable, Realistic, Time-bound).

5. 5

   Experimenting to Overcome Obstacles

   20 min

   Groups identify experiments or actions to undertake to reach their target. The facilitator asks: "What actions can we try to overcome our obstacles?" Each group plans an experiment, documents it, and shares it.

   Tip — Remind participants that experimentation often involves failures, and these are learning opportunities.

6. 6

   Conclusion and Summary

   10 min

   The facilitator invites each group to briefly present their planned experiment and the expected learnings. They summarise the key points of the Improvement Kata and encourage participants to apply this method in their daily work.

   Tip — End with an inspiring quote on continuous improvement to motivate participants to take action.

Variants

• Integrate real case studies to illustrate each step of the Kata.
• Use digital tools to facilitate remote collaboration.
• Offer a competitive version where teams must reach their target before others.
• Adapt the game to focus on personal improvement rather than professional.
