The concept builds on the disciplinary foundations of MRP II . Introduces innovative manufacturing concepts such as more efficient assembly line layouts, reduced machine setup times, smaller lot sizes, flow operations, grouping of similar operations, team production, and other techniques that streamline the operation and maximize the flexibility of the manufacturing cycle. Evolved from manufacturing techniques used in Japan, e.g. Toyota. Replaces the traditional push system of manufacturing based on incoming customer orders, or continuous production, with a pull system where one tries to produce only what is necessary, when it is required, using the fewest possible resources and the least possible time. JIT sends replenishment signals back from the point of sale or send order schedules in advance of anticipated demand, calling for the exact amount of materials to arrive exactly when they will be needed.
Suppliers act upon more reliable advance orders.
Means that just in time is valid only for the customer. Geo-graphical proximity to the customer could be one solution to this dilemma but this means again an increase in dependency for the supplier. Idea of the concept ok, but often implemented by powerful customers, acting in their very own interests, trying to improve internal efficiencies. Research Triangle, 1997. Last updated March 18, 1998.
