Change to lean in reality Top Management s commitment and involvement is the most important factor for success. One must have a clear goal and production strategy. Lean is not the goal but means to achieve the goal and realize the strategy. Implantation of the tools is not the goal, they are simply the help of problem solving.

Change to lean in reality It is much about changing soft part of the organization (leadership, mindset & behavior, culture, alignment). 70% efforts can be related to this. It is not a liner but complex process that involves not only technical but cultural, political, and learning dimensions. The change is much context dependent. There is no one best way to change to lean.

Kaizen Advantage Smaller risk for each changes No need for large investment Stimulates person s motivation and involvement Necessary to build and sustain Just In Time production May become large impact when accumulated Concept and method are well established Disadvantage Improvement is based on previous experience Scope is small thus improvement is often small Improvement speed may not catch up with the speed of change in the business environment

Kaikaku- radical/innovative improvement Pro oduction perform mance Kaizen Time Kaikaku k Higher speed of improvement than Kaizen Top down initiative Stretched goal setting Fundamental rethinking of the current production system Innovative thinking Large scale of change

Stretched goal It is impossible to achieve the goal with the current system/ way of working. You have do in another way! Target Creative tension Current Think outside of the box
