Document Summary

Just-in-time (jit): a highly coordinated processing system in which goods move through the system, and services are performed, just as they are needed usually small batches (ideal size = 1) pull (demand) system. Big jit= philosophy of waste reduction and continuous improvement = lean production. Goals: ultimate: balanced system: eliminate disruptions, make system flexible, eliminate waste, continuous improvement (kaizen) Sources of waste: overproduction, over processing, product defects, unnecessary transportation, unnecessary inventory, waiting time, employee underutilization. Jit systems require high quality levels, the systems are geared to a smooth flow of work, the appearance of problems due to poor quality creates disruption in this flow. Becomes imperative to avoid shutdowns, and quickly resolve problems when they occur. Make workers responsible for producing goods of high quality. Jit production requires a smooth flow of goods through the system to achieve a meshing of the different operations and the movement of goods and materials from the supplier to the final output.
