Overprocessing or performing unnecessary or excessive steps in the production process adds no value to the final product. JIT focuses on optimizing layouts, workstations, and assembly lines to minimize wasted motion and improve ergonomics. JIT seeks to streamline material flow and eliminate inessential transportation steps or distances.Įxcessive motion of people or equipment wastes time and energy. Unnecessary transportation of materials or products within the production process is also wasteful. Companies often rid themselves of excess inventory by selling it at a reduced cost or tossing it out, either of which can lower profits significantly. Either way, it hurts business because it takes up space and must be managed. Some estimates claim that more than 90 percent of a product’s time in manufacturing is spent waiting.Įxcess inventory typically means that a company has ordered more than the market demands or the demand falls dramatically after the inventory is ordered. The flow of all operations should be efficient and continuous. Waiting to begin one process until another one finishes is ineffective and a colossal waste of time. It’s considered to be the most severe of the wastes by proponents of just-in-time manufacturing because it squanders time, space, and money, all the while masking the other problems within a company’s processes. Overproduction is manufacturing products in advance of or more than the demand specifies. Let us take a look at the seven types of manufacturing wastes that JIT addresses in a bit more detail. This results in reduced standing inventory, labor costs, storage space, throughput time, etc. JIT is geared toward eliminating waste arising from inefficient manufacturing.
#A JUST IN TIME INVENTORY SYSTEM USUALLY REDUCES COSTS FOR FOR FREE#
Accurate demand forecasting is thus a prerequisite of this production and inventory model.Īlthough JIT grew out of the automotive industry and remains very popular there, the methodology can be implemented in practically any industry sector.Įasily manage just-in-time manufacturing with MRPeasy Try for free Just-in-Time manufacturing vs. The just-in-time inventory model, on the other hand, aims to order goods so that they would arrive just in time for their consumption. It is similar to lean manufacturing and the terms are sometimes used interchangeably.Īlso known as short-cycle manufacturing, JIT aims to produce exactly what, when, and how much was ordered – either by the next workstation sequence or the customer. Just-in-time manufacturing, or JIT, is a production methodology designed to meet demand as exactly as possible while minimizing waste and extra costs associated with creating surplus goods.
