Since 1890, Frederick W. Taylor innovated by studying and publishing about scientific work management, which as a consequence, was responsible for the formalization of the study of times and pattern establishment. Frank Gilbert added the work decomposition to these newly developed concepts.
Therefore, the first concepts for waste elimination and movement study appeared.
In 1910, Henry Ford invented the assembly line for the Ford T and, immediately after, Alfred P. Sloan perfected the Ford system by introducing in GM the concept of diversity in the assembly lines.
After the Second World War, Taiichi Ohno e Shingeo created for Toyota the “pull system” concepts and, together with other flux introduction techniques, they created the Toyota Production System (TPS).
From that moment on, TPS never stopped evolving and perfecting. In 1990, James Wormarck systematized these concepts to form the Lean-Manufacturing, while the japanese “know-how” spreads in the West, as the success becomes evident in companies that apply these principles and techniques.
