In the context of the ITIL continual improvement model, Toyota Kata helps to answer the following questions:
- Step 1: What is the vision?
- Step 2: Where are we now?
- Step 3: Where do we want to be?
- Step 4: How do we get there?
Digitally enabled organizations are always under particular pressure to improve their performance continually under changeable market conditions. Circumstances are often unpredictable. It makes it difficult or even irresponsible to create and follow predetermined plans for large changes. Improvements happen step-by-step based on sound interpretation of available information.
Changing circumstances require organizations to be flexible and creative in the way they define ways to improve. At the same time, improvement initiatives should be disciplined, data-driven, and justified. It requires:
- Belief in scientific thinking
- Disciplined execution
- Practice to unlearn old habits, and learn and sustain new ones
- Confidence and competence for improvement when appropriate
Disciplined scientific thinking with incremental improvements reduces our natural bias to jump to the wrong conclusions. Practice and coaching help us form and sustain new habits, after which we can start improvising. One approach to scientific experimentation is Toyota Kata.
