Lean manufacturing is based on continuous finding and removal of the wastes. Value is defined
from the customer’s point of view. Therefore all the tools in lean manufacturing aim to identify and
remove wastes from the system continuously. There are four steps in implementing lean
manufacturing. They are; 1. Identifying the fact that there are wastes to be removed, 2. Analyzing
the wastes and finding the root causes for these wastes, 3. Finding the solution for these root causes,
and 4. Application of these solutions and achieving the objective.
