Just-in-time (JIT) is an inventory strategy.

It is also called the Toyata Production System.

It focuses on continuous improvement .

This saves warehouse space and costs.

Its effective application cannot be independent of other key components.

Philosophy of JIT is simple: inventory is waste.

The company must follow an array of new methods.

It relates to management.

JIT is implemented without an awareness.

The JIT system has broad implications for implementers.

Just- in- Time is simply an English phrase.

There is no suitable Japanese equivalent for this.

They had so much excess capacity.

They were getting their steel ‘Just in Time”.

Some people believe, was originally developed at the Toyota motor company in Japan.

Originated in Japan.

JIT is also known as stockless production or lean production.

JIT is a suitable production system when:

I. A reasonable number of units made.

II. A high value product.

III. Short setup times on machines.

KanbanI. Used to control the flow of items though the

production process.

It is often said that:

I. Materials requirement planing(MRP)= a 'Push' system

II. JIT = a 'Pull' system.

o JIT is a system based on actual usage.

To reduce the set up times and lot sizes.

To achieve ‘zero defect’ goal in manufacturing.

To reduce inventories and thus economise on inventory carrying costs.

To eliminate all non-value adding activities.

To concentrate on involving workers.

By acquiring higher stocks, the productivity problems get hidden.

The old thinking that JIT is low inventory management system.

It is rather a philosophy or an approach to management.

It is extremely intolerant of failure of: suppliers to supply, people to perform and equipment to work.

The used by various companies under waste elimination techniques JIT are as below:

I. Batch size reduction.

II. Group technology layout.

III. Balanced scheduling.

IV.Set up time reduction.

V. Flexible and multi function workforce.

VI.Scientific machine and factory design.

The main JIT methods are as below:

I. Waste elimination through problems exposure.

II. Lead time reduction.

III. Set up time reduction.

IV. Mistake proofing.

V. Production rule.

VI. Process stopping for defect.

Regular meeting of the workforce. Discuss work practices, confront and solve

problems. Modify machinery, e.g. to reduce setup time. Reduce buffer stock. Reveal bad practices. Take away the "security blanket" of stock.

Reduced set up times in warehouse.

Employees who possess multi-skills are utilized more efficiently.

Better consistency of scheduling and consistency of employee work hours.

Increased emphasis on supplier relationships.

Supplies continue around the clock keeping workers.

If the company wants to have a JIT concept.

Have good organized resource allocation.

Implementation and development of JIT is a long-lasting.

The JIT concept is only one part in the value chain.

Synergy is the only thing that can improve business results.
