A Healthy Lean Road is Paved with Exercise
Lean is a journey that never ends. There will always be a gap between where you are (current state) and where you would like to be (True North). Since there will always be a gap, there will always be an opportunity to improve. Walking the path on a Lean journey can be an overwhelming experience.
A Lean journey is full of steps not all of which are forward. Failure will occur. Its ok, the purpose is learning, and we learn through experimentation. Trying new approaches, exploring new methods and testing new ideas for improving the various processes is exercise for the mind.
Lean grew out of years of practice and experimentation at Toyota. No matter how much better they are than their competition, they continue to find more and more opportunities to improve each and every year. Lean involves the creation and implementation of continuous experiments to improve your strategies over time. This means experimenting with every process every day to get it right. We learn problem solving through hands-on improvement experiments. In Toyota and in lean thinking, the idea is to repeat cycles of improvement experiments forever.
So leaders must create a culture that puts failure in its proper place: a useful tool for learning, and a natural part of iterative experimentation. Management must avoid the temptation to harshly judge unsuccessful ideas. A leader who allows for experimentation sends a clear signal that personnel are encouraged to find better methods and products.
Organizations embarking on a Lean journey should follow a disciplined process of systematic exploration and controlled experimentation. Kaizen is the process which determines whether processes resulted in improvements. It refers to an on-going activity by all people (including managers) to relentlessly and incrementally change and improve practices in small experiments.
The road to continual improvement is a rocky one with many ups and downs. Value the incremental improvement approach to continuous improvement. Through simple, common-sense, and low cost experimentation a great deal of process improvements can be made. Experimentation is the exercise of a healthy Lean journey. Understanding this allows one the opportunity to begin the journey.
