Twenty One: Just-in-Time Manufacturing (Continued) JIT is a management philosophy that seeks to eliminate all forms of waste. As a production system, JIT produces only what is needed, when it is needed, in the quantity needed. Taiichi Ohno is credited with the development of the Toyota Production System and JIT. The root justification for JIT is improved product quality with lower costs.

Twenty One: Just-in-Time Manufacturing (JIT) (Continued) JIT began as a means of reducing the seven wastes. Over time, the JIT system came to be a pull system whose small lot production is supported by reduced setup times. Total productive maintenance and statistical process control were integrated to provide the necessary production reliability and predictability. Continual improvement provides the vehicle for the relentless attack on all wastes. JIT is at its best as a part of a total quality system. Results can be severely restricted when JIT is operated without the total quality umbrella.

Twenty One: Just-in-Time Manufacturing (JIT) (Continued) Inventory reduction, shortened cycle time, continual improvement and elimination of wastes are all inherent benefits of JIT. JIT has a different set of requirements from traditional production systems:  New skills training  Rationalizing production flow for the pull system  Empowering operators to take advantage of JIT’s visibility features  Guarding against bottleneck vulnerability through TPM  Process capability study, SPC, and continual improvement  Small lot sizes and short setup times  Close working relationships with superior suppliers

Twenty One: Just-in-Time Manufacturing (JIT) (Continued) Although JIT is compatible with automation, some of the world’s best plants use JIT with very little automation. World-class manufacturing employs JIT as an integral part of a total quality system, producing the highest quality products at competitive prices. It is not related to the presence or absence of automation.
