Who invented the third-generation lean management?

Who invented the third-generation lean management? Regarding the inventor of the third-generation lean management, I would like to elaborate on the following aspects in the hope of helping everyone!

The origin of lean management:

The concept of lean management was initially proposed by Toyota, originating in the 1990s as a management philosophy derived from the Toyota Production System (TPS). The core of this concept lies in "refinement" and "benefit", which means reducing input and consumption, improving economic efficiency and output quality.

The first generation of lean management:

The initial form of lean management is closely related to the Toyota Production System, emphasizing the achievement of business goals through optimizing production processes, reducing waste, and improving efficiency. However, there is no clear record or documentation regarding the specific inventor or designer of the first generation lean management.

Second generation lean management:

The second generation of lean management applies the concept of lean management to all business processes and systems of the enterprise from the perspective of the entire value chain. This stage of lean management emphasizes comprehensiveness and systematicity, but it also lacks a clear inventor record.

Third generation lean management:

The characteristics of the third generation lean pipe are its aluminum alloy material and a wider variety of accessories. The third generation of lean management is described as "designed in Germany" and is more common in the eastern region. However, this does not mean that Germany is the inventor of the third generation of lean management, but rather that Germany has contributed to the development and application of lean management technology.

The concept of lean management was initially proposed by Toyota, but there is no clear record or information about which specific generation of lean management inventors. Germany may have contributed to the technology and application of third-generation lean management, but this does not mean that Germany is its inventor. The development and evolution of third-generation lean management is a continuous process involving contributions from multiple countries and enterprises.
