**Abstract**

The principles and concepts originated mainly in Toyota in the 1950s and now presented in models such as Lean Thinking, Shingo Model, and The Toyota Way itself are powerful ideas to bring success to organizations, but the path is not easy. In theory, there are two main features to reach effective and sustainable success, the right vision (True North) and continuous improvement toward that vision. Those two main features are as easy to understand as they are difficult to accomplish. Even when senior leaders have full understanding and belief, the effective implementation on a daily basis is an enormous challenge. This chapter will show how organizations can implement sustainable and stable continuous improvement systems. It will describe the principles that must be followed, the necessary requirements that must be fulfilled, the way the organizations must be structured in teams, the necessary routines, and all the practical steps necessary to reach that sustainable and stable continuous improvement system.
