Lean Manufacturing Just In Time

Manufacturing is a wealth-producing sector of an economy

, whereas a service sector tends to be wealth-consuming. Emerging technologies have provided some new growth in advanced manufacturing employment opportunities.

Material and machinery are the most important part of any manufacturing process. They contribute around 60-70% of project cost. So, all the decisions about material and equipment are very important for every manufacturing firm. These decisions are taken as Just in Case or Just in Time Concept of Just in Time system comes under Lean Management. Decision making in manufacturing firms is a matter of concern, as most of the decisions are made on the basis of Just in Case.

Just to understand, a product with many component specification changes is better satisfied by a Just in Time system, which has more frequent shipments and smaller batch inventories on hand, so a spec change can be translated to the product more quickly. A spec change won't obsolete as many parts. Products with a low incidence of changes to go out of date may be satisfied by Just in Case.

Also Just in Case systems, lead manufacturing companies to over processing and excess inventory. These two factors cause the major problems in terms of high cash block.

Another problem would be of throughput time (period required for a material, part, or subassembly to pass through the manufacturing process) would be possibly high as decisions are made on the basis of the situations which can be happened Just in Case.

With the help of Lean Manufacturing tools such as JIT, Kanban this issue can be addressed with ease.

Lean Manufacturing drastically reduces through put time; increases inventory turns and thereby improves cash flow, resulting in higher profitability.
