What is the fundamental goal of Just-In-Time (JIT) in the Toyota Production System (TPS)?
To produce only what is needed, when it is needed, and in the quantity needed, eliminating overproduction and reducing inventory levels.
What role do suppliers play in a Just-In-Time system?
Suppliers are expected to deliver materials in small, precise quantities at exactly the right time, helping reduce excess inventory and promoting smooth flow.
How does JIT contribute to increased responsiveness to customer demand?
JIT allows for flexible production adjustments to meet changing customer demands quickly, ensuring the company produces only what customers need at that time.
Define Takt Time in the context of lean manufacturing
Takt Time is the rate at which products must be produced to meet customer demand, calculated by dividing the available production time by customer demand.
How does Takt Time differ from Cycle Time?
akt Time refers to the customer-driven pace of production, while Cycle Time is the actual time it takes to complete a production process.
How do you calculate takt time in a production process?
Takt time = Available production time / Customer demand
What is the “pull system” in JIT, and how does it work?
The pull system ensures that production is based on actual demand rather than forecasts. Each step in the process pulls from the previous step only when needed.
What is the relationship between JIT and Kanban in the Toyota Production System?
Kanban is a signaling system used in JIT to visually communicate the need to replenish materials or products, ensuring that only what is needed is produced or ordered.
How is continuous flow different from batch production in Lean manufacturing?
Continuous flow produces one unit at a time, passing it smoothly between processes, whereas batch production creates large quantities before passing them to the next step, leading to potential delays and waste.
