In the same product category, the line speed should remain consistent. However, when different products are being produced on the same line, the speed may change. Additionally, the presence of new employees can cause a slowdown in the line's efficiency.
1: Is the production pipeline always moving from left to right or right to left?
Typically, pipelines flow from left to right because most people are right-handed and find this direction more natural. However, due to space constraints in some facilities, it's possible that one or more lines may run in the opposite direction.
2: Is a U-line the best layout for all situations?
Not necessarily. The layout of the production line should be based on the characteristics and process requirements of the product being manufactured.
3: Does faster line speed mean higher production capacity?
No, production capacity depends on the bottleneck process and the cycle time of each station. Forcing the line to move faster can lead to inefficiencies, defects, and other operational issues.
4: Is the main purpose of an assembly line to transport products?
Not entirely. The ultimate goal is to create a continuous flow of value-added work, not just to move products from one point to another.
5: Why is the output low during shift changes or when starting work?
This is a transitional phase with many adjustments happening. Effective shift management is crucial to maintain productivity and reduce disruptions.
6: Should the line speed be kept constant every day?
In the same product category, the speed should remain consistent. However, when switching between different products, the speed may need to be adjusted. New employees may also slow down the line.
7: Can I place only one product per cell at the pitch mark?
Not necessarily. The focus should be on maintaining a smooth and balanced production flow rather than limiting the number of products per cell.
8: Is it better to have a faster pre-assembly speed and more buffer stock?
No, it’s better to produce according to demand. However, pre-assembly can be slightly faster than the actual assembly to help maintain a steady workflow.
9: Do we use the line length to remind workers to do their job correctly?
The first two points are correct—kanban helps track progress and the line length can indicate workload. However, constantly urging workers can lead to mistakes and unnecessary stress.
10: If someone is absent, can’t we just reassign workers? What if we can't borrow staff?
Assembly lines rely on teamwork. It’s rare that one person can complete all tasks alone. While a small drop in productivity might occur, it's usually manageable. But what about emergency plans? Managers often overlook these common issues, which raises questions about their preparedness.
11: Is it better for workers to stand or sit during production?
It depends on the product, working conditions, and available equipment. Both options have their advantages depending on the situation.
12: Should the containers on the line be dedicated or universal, and what size should they be?
Most designs aim for generic containers that can be used across multiple products, but they shouldn’t be completely universal.
13: What is the ideal height for the production line and the machine?
According to ergonomic principles, sitting tables should be between 65–75 cm high, with seats around 38–45 cm. For standing stations, the table height should be 85–95 cm, and the seat should be 58–62 cm. A footrest of 20–30 cm is also recommended.
