• Summary
Just-In-Time Manufacturing:
A Definition
• Uses a systems approach to develop
and operate a manufacturing system
• Organizes the production process so
that parts are available when they
are needed
• A method for optimizing processes
that involves continual reduction of
waste
Central Themes Surrounding

A Reason for Changing
Executive Commitment
Strategic Manufacturing Plan
Commitment to Action
Just-In-Time
Techniques
• Inventory Reduction as a Tool
for Improvement
• Supplier Relationships
• Inventory “Pull”
• Uniform Plant Loading
Just-In-Time
Techniques(cont’d)
• Reduced Setup Times
• Shop-Floor Layout and
Production Cells
• Total Quality Assurance
• Preventive Maintenance
Brainstorming Exercise:
• How can Just-In-Time
Manufacturing be Effective in
your Business?
A Competitive Edge
• Integrating and Optimizing
• Improve Continuously
• Understanding the Customer
The Major
Misconceptions of JIT
• JIT is Only an Inventory Control
System
• It is a Method to “Push”
Inventory Back to the Supplier
• JIT is a Quality Control Program
Goals of Just-In-Time
Systems
• Design for Optimum Quality and
Cost
• Minimize resources needed for
Design and Manufacturing
• Be Responsive to the Customers
Needs
Goals of Just-In-Time
Systems(cont’d)
• Develop Trust and Open
Relationships with Suppliers and
Customers
• Develop a Commitment to
Improve the Total Manufacturing
System
