2. What Is Just-in-Time (JIT)?
The just-in-time (JIT) inventory system is a management strategy
that aligns raw-material orders from suppliers directly with production
schedules. Companies employ this inventory strategy to increase
efficiency and decrease waste by receiving goods only as they need
them for the production process, which reduces inventory costs. This
method requires producers to forecast demand accurately.
The JIT inventory system contrasts with just-in-case strategies,
wherein producers hold sufficient inventories to have enough product to
absorb maximum market demand.
3. Objective of JIT
The objectives of JIT is to change the manufacturing system gradually
rather than drastically:
1. To be more responsive to customers,
2. To have better communication among departments and suppliers,
3. To be more flexible,
4. To achieve better quality,
5. To reduce product cost.
5. JIT as a Philosophy
• Elimination of waste
• Continuous improvement/One Less at a Time
• Problems as opportunities
• Quality at the source
• Simplification
• Visual Control
• Focus on Customer Needs
• Production to Customer Demand
6. Principle of eliminating the wastes
The principle of eliminating the wastes includes:
• All waste should be eliminated.
• Waste can gradually be eliminated by removing small amounts of inventory
from the system, correcting the problems that ensue, and then, removing more
inventory.
• The customers' definitions of quality should drive product design and
manufacturing system.
• Manufacturing flexibility is essential to maintain high quality and low cost
with an increasingly differentiated product line.
• Mutual respect and support should exist among an organization, its employees,
its suppliers, and its customers.
• A team effort is required to achieve world class manufacturing capability.
• The employee who performs a task is the best source of suggested
improvements.
