WHAT IS JUST IN TIME ?

Production system that allows the firm to produce what is needed in the right quantity and at the right time.

This means that stocks of raw materials, components and finished goods can be kept to a minimum and at once it can minimize cost of storage. This process must have a carefully planned scheduling and systematic production system . In modern manufacturing firms use production scheduling software to plan production for each period of time, which includes ordering the correct stock. Information is exchanged with suppliers and customers through EDI (Electronic Data Interchange) to help ensure that every detail is correct.

Supplies delivered directly to the production line only when they are needed. For example, a car manufacturing plant may receive the necessary components with the right amount and the right type of tire for the production of the day.

Supplies delivered directly to the production line only when they are needed. For example, a car manufacturing plant may receive exactly the right amount and type of tire for the production of a single day, and suppliers are expected to be delivered to the correct payload bay on a production line in a very narrow time slot.

HISTORY OF JUST IN TIME

Just-In-Time is a Japanese manufacturing management method developed in 1970s. It was first adopted by Toyota manufacturing plants by Taiichi Ohno. The main concern at that time was to meet consumer demands. Because of the success of JIT management, Taiichi Ohno was named the Father of JIT.

After the first introduction of JIT by Toyota, many companies followed up and around mid 1970s’, it gained extended support and widely used by many companies.

One motivated reason for developing JIT and some other better production techniques was that after World War II , Japanese people had a very strong incentive to develop a good manufacturing techniques to help them rebuilding the economy. They also had a strong working ethnic which was concentrated on work rather than leisure, seeked continuous improvement, life commitment to work, group conscious rather than individualism and achieved common goal. These kind of motivation had driven Japanese economy to succeed.

IDEAS OF SUZAKI FOR THE OBJECTIVES OF JIT

• ·         Increasing the organization’s ability to compete with others and remain competitive over the long run. The competitiveness of the firms is increased by the use of JIT manufacturing process as they can develop a more optimal process for their firms.
• ·         Increasing efficiency within the production process. Efficiency is obtained through the increase of productivity and decrease of cost.
• ·         Reducing wasted materials, time and effort. It can help to reduce the costs.
