There are 4-core areas. TPS is famous, but itfs just a small part of the total Toyota Production System, which includes production planning and design. Each of the other parts are also important for understanding Toyotafs systematic approach to production and knowledge work.

Each phase starts with concept and design. The concept phases are important to anticipate issues and resolve them prior to implementation.
