The '5S' methodology stands for Sort, Set in Order, Shine, Standardize, and:
Answer: Sustain
The fifth S is Sustain, which ensures the other four steps are maintained and become part of daily routine.
What is 'poka-yoke' designed to do?
Answer: Prevent errors or make them immediately obvious
Poka-yoke is an error-proofing technique that prevents defects by making it impossible or difficult to make mistakes.
In lean, 'overproduction' is considered the worst waste because:
Answer: It generates all other wastes by producing more than needed
Overproduction leads to excess inventory, transportation, storage costs, and masks other process problems.
Which lean concept involves producing one unit at a time through a sequence of operations?
Answer: One-piece flow
One-piece flow moves single units through production steps sequentially, reducing WIP and lead times.
A 'pull system' in lean manufacturing means:
Answer: Production is triggered by actual customer demand
In a pull system, downstream demand signals upstream processes to produce, preventing overproduction.
What is 'heijunka' in lean manufacturing?
Answer: Production leveling to smooth out demand variation
Heijunka is the practice of leveling production volume and mix over time to reduce variability and waste.
