Lean Manufacturing has been adopted by a large number of companies because it increases productivity, improves quality and reduces costs, while cutting production cycle times. Lean Manufacturing is a philosophy rather than a methodology. It focuses on reducing "8 wastes" and is based on the key principles of Customer Value, Continuous Improvement and Respect for the Individual.

Lean Engineering, is an approach based on the concept of Lean management, which aims to minimize waste and maximize productivity in operations management. In the context of engineering or R&D, this means optimizing design and project delivery processes to be more efficient, while ensuring quality and meeting deadlines and budgets.

Waste reduction (mudas in Japanese) is a central concept in the Lean philosophy which seeks to minimize them while maximizing productivity and increasing customer satisfaction.

How many times have we looked for Lean manufacturing assessment tools or analysis tools, such as Lean maturity Excel scoring? For my part, often by spending a lot of time on Google or by asking my fellow consultants. With not always satisfactory results.
