Jidoka:
The concept of adding an element of human judgment to auto­mated equipment. In doing this, the equipment becomes capable of discriminating against unacceptable quality, and the automated process becomes more reliable. This concept, also known as autonomation, was pioneered by Sakichi Toyoda at the turn of the twentieth century when he invented automatic looms that stopped instantly when any thread broke. This permitted one operator to oversee many machines with no risk of producing large amounts of defective cloth. The term has since been extended beyond its original meaning to include any means of stopping production to prevent scrap (for example the andon cord which allows assembly-plant workers to stop the line), even where this capability is not built-in to the production machine itself

Joint Photographic Expert Group (JPEG):
A computer term which is an abbreviation for the Joint Photographic Expert Group. A graphical file format used to display high-resolution color images on the World Wide Web.

Just-in-Time (JIT):
An inventory control system that controls material flow into assembly and manufacturing plants by coordinating demand and supply to the point where desired materials arrive just in time for use. An inventory reduction strategy that feeds production lines with products delivered "just in time”. Developed by the auto industry, it refers to shipping goods in smaller, more frequent lots.
Just-in-Time II (JIT II):
Vendor-managed operations taking place within a customer's facility. JIT II was popularized by the Bose Corporation. The supplier representatives, called "inplants," place orders to their own companies, relieving the customer's buyers from this task. Many also become involved at a deeper level, such as participating in new product development projects and manufacturing planning (concurrent planning).
