An Overview of Just-In-time (JIT)
Just-In-Time (JIT), is a management pull system used for planning and control operations that used for producing, manufacturing and supplying the needed products and services at the right place, when they are needed, and at the exact ordered quantities. The distinctive feature of JIT is to eliminate all kind of waste by organising the entire system operations and activities.
The JIT system represents the whole continuous improvement processes throughout the entire company system, and it could be applied into both production and purchasing systems within any organisations.
JIT focuses on the complete elimination of waste, which could be any thing that does not add any more values to the produced products and services. In addition, the modern manufacturing organisations consider the successful JIT implementation is a key factor for minimising inventory and maximising the quality of products and services
The overall philosophy of JIT aims to minimise the total costs and inventory/storage items through pursuit of continuous improvement of all the operations and processes throughout the entire production and service systems. That could be achieved through setting well-organised networks for producing and transporting the right items exactly in the right time with the right quantities needed, establishing a long term relationship with vendors to maintain regulated shipments to minimise ordering cost, and to buy enough parts as needed to avoid paying holding costs. Also, to encourage the entire supply system channels to respond to all customers and operations requirements
