Elements of Just in Time

According to Cheng, the basic elements of JIT manufacturing are:
• People Involvement
• Plants
• System

People Involvement
Maintaining a good support and agreement from people involved in production. This is not only reduce the time and effort in implementation of JIT, but also minimize the chance of creating implementation problem. The attempt to maximize people’s involvement may carry through the introduction of quality circle and total involvement concept.

Manufacturers can gain support from 4 sources.
1. Stockholders and owners of the company - should maintain a good long-term relationship among them.

2. Labor organization - all labors should be well-informed about the goals of JIT, this is crucial in gaining support from the them.

3. Management support - support from all level of management. The ideas of continuous improvement should spread all over the factory, managers and all shop-floor labor.

4. Government support - government can show their support by extending tax and other financial help. This can enhance the motivation, and also help in financing the implementation of JIT.

Plants
Certain requirements are needed to implement JIT, there are:
1. Plant layout - the plant layout is mainly focus on maximizing working flexibility. It requires the use of "multi-function workers".

2. Demand pull production - it means to produce when the order is received. This can manage the quantity and time more appropriately.

3. Kanban - a Japanese term for card or tag. Special inventory and process information are written on the card. This helps tying and linking the process more efficiently.

4. Self-inspection - it is carried out by the workers at catch mistakes immediately.

5. Continuous improvement - this concept should be adopted by every members in the organization in order to carry out JIT. This is the most important concept of JIT. This can allow an organization to improve its productivity, service, operation and even customer satisfaction in an on-going basis.
System


This refers to the technology and process that combines the different processes and activities together. Two major types are MRP(Material Requirement Planning) and MRP II (Manufacturing Resource Planning).
MRP is a computer-based, bottom-up manufacturing approach.

This involves two plans, production plan and master production schedule. Production plan involves the management and planning of resources through the available capacity. Master production schedule involves what products to be produced in what time.

MRP II is mainly involved the management or planning of financial resources in order to carry out the operation.

The above three factors formed the element of JIT.

That's a great explanation for elements of Just In Time principle. This description gives glimpse of the
just in time concept and just in time meaning. It can be applied to various industries like

just in time watches
just in time inventory
just in time pdf
just in time manufacturing etc
I'd really appreciate if you can create a just in time ppt for just in time advantages and disadvantages as well. Thanks.
 
Goals of just in time

1. Identify and response to consumers needs

2. Optimal quality/cost relationship

3. Reduce unwanted wastes

4. Develop a reliable relationship between the suppliers

5. Plant design for maximizing efficiency

6. Adopt the work ethnic of Japanese workers for continuous improvement
