Taiichi Ohno (February 29, 1912-May 28,1990) is considered by many to be the father of the Toyota Production System. He eventually rose to the rank of executive vice president in the company.

He was able to lay the foundation for kanban systems, pull, and one-piece flow by changing the way components were supplied to production processes.
