What are the elements of just-in-time inventory system?
- waste from overproduction.
- waste of waiting time.
- transportation waste.
- processing waste.
- inventory waste.
- waste of motion.
- waste from product defects.
What are the three major elements of JIT?
The three elements of JIT are 1) Takt Time, 2) Flow Production, and 3) a Pull System.
What companies use JIT?
Some successful companies practising JIT systems include Toyota, Apple and McDonald's .
How does McDonald's use JIT?
Before used JIT method, Mc Donald's Fast Food Restaurant, using the traditional strategy which is pre cook all the burgers and place them under the lamps to keep them hot. ...

Why is just in time so successful?
Just-in-time manufacturing is focused on efficiency , while lean manufacturing is centered on using efficiency to add value for the customer. ... The JIT process adds value by increasing efficiency. The most important benefit of JIT is the elimination of raw material, inventory and product storage costs.
How do you practice JIT?
- Housekeeping – physical organization and discipline.
- Elimination of defects.
- Setup reduction and flexible changeover approaches.
- Small lot sizes.

- preventing over-production.
- minimising waiting times and transport costs.
- saving resources by streamlining your production systems.
- reducing the capital you have tied up in stock.
- dispensing with the need for inventory operations.
- decreasing product defects.
What are the advantages and disadvantages of just in time?
| Advantages Disadvantages | There is less likelihood of stock perishing, becoming obsolete or out of date There is no spare finished product available to meet unexpected orders, because all product is made to meet actual orders – however, JIT is a very responsive method of production |
|---|
- JIT cuts the cost of quality.
- JIT improves quality.
- Better quality means less inventory and better, easier-to-employ JIT system.
Overall, JIT is a pull system that focuses on producing what is necessary when it is necessary and in necessary amounts allowing the pursue of quality, cost minimization, delivery time and waste reduction, while TQM aims to improve quality by continuous improvements of operations to guarantee free defects products .
