Push vs Pull Systems in Production

The video tutorial explains the five principles of lean, focusing on the differences between push and pull systems. In a push system, each step works as fast as possible, often leading to bottlenecks and waste. Conversely, a pull system aligns production with customer demand, enhancing flexibility and reducing waste. The tutorial uses simulations to illustrate these concepts, highlighting the benefits of transitioning from push to pull systems, such as increased throughput and adaptability.

What are the five principles of lean discussed in the video?

• Design, development, testing, deployment, maintenance

• Value, value stream, flow, pull, perfection

• Efficiency, speed, cost, quality, delivery

• Planning, execution, monitoring, control, closure

In a push system, how does each step in the process operate?

• As fast as possible, regardless of demand

• In response to market trends

• At the speed of the customer

• Only when defects are identified

What is a common issue found in push systems?

• Reduced waste

• Balanced production

• Bottlenecks and inefficiencies

• Increased flexibility

What is a potential consequence of a defect in a push system?

• Immediate detection and correction

• Increased customer satisfaction

• Long delays before detection

• No impact on production

In a push system, what often happens when there is a bottleneck?

• Waste is eliminated

• Customer demand decreases

• Blame is assigned to bottleneck workstations

• Production speeds up

How does a pull system determine the pace of production?

• Through random selection

• According to customer demand

• By the fastest step in the process

• Based on historical data

What happens to production speed in a pull system when customer demand changes?

• It decreases significantly

• It increases regardless of demand

• It adapts to the new demand

• It remains constant

What is the role of the customer in a pull system?

• To reduce throughput

• To increase inventory levels

• To dictate the production speed

• To create bottlenecks

What is one of the main advantages of a pull system over a push system?

• Slower response times

• Greater adaptability to customer needs

• Higher inventory costs

• Increased waste

What is a key benefit of moving from a push to a pull system?

• 30% increase in throughput

• Decreased throughput

• Higher defect rates

• Increased waste
