2. Just in Time:
Aim: “The right material, at the right time, at the right place, and
in the exact amount”, without the safety net of inventory

3. Just in Time Philosophy:
• Supplying "what is needed, when it is needed, and in the
amount needed“
• Making "only what is needed, when it is needed, and in
the amount needed.“
• “the storage of unused inventory is a waste of resources”
• The focus of JIT is to improve the system of production
by eliminating all forms of waste.
• JIT is long time approach to process improvement. It
uses timelines as a level to lower costs, improve quality
and improve responses.

4. Just in Time Functions

5. JIT Manufacturing Building Blocks
1. Product design
2. Process design
3. Personnel/organizational elements
4. Manufacturing planning and control

6. • Standard product configuration and standart parts
• Reduced number of parts
• Modular design
• Concurrent engineering
• Highly capable production systems
1. Product Design

7. 2. Process Design
• Small lot sizes
• Setup time reduction
• Cellular layout (Manufacturing cells)
• Reduced Inventories (Limited WIP)
• Continuous quality improvement
• Production flexibility (multifunctional workers, general
purpose machines)
• Balanced system
• Fail-safe methods

8. 3. Personnel/Organizational Elements
• Workers as assets
• Cross-trained workers
• Employee empowerment
• Continuous improvement
• Cost accounting
• Leadership/project management
• Commitment

9. 4. Manufacturing Planning and Control
• Uniform production levels
• Level loading (level schedules)
• Pull systems
• Visual systems
• Reduced transaction processing

10. JIT focuses on eliminating the Waste which includes
anything that does not add value to the product or
service.
Some common example of waste are :
• Waste From Overproduction.
• Waste Of Waiting Time.
• Transportation Waste.
• Processing Waste.
• Inventory Waste.
• Waste Of Motion.
• Waste From Product Defects.

11. Pillars of JIT
• Set-up Time reduction
• Total Quality Management
• Vendor Relations
• Flexible Resources
• Employee Involvement
• Inventory
• Product defects

12. Comparison of JIT and Traditional Systems

13. Benefits of JIT
1.Reduced inventory
2.Improved quality
3.Lower costs
4.Reduced space requirements
5.Reduced lead times
6.Increased productivity
7.Greater flexibility
8.Reduced scrap and rework
