LMC Tools and Techniques in Lean 3

Question 1

What distinguishes a 'pull' system from a 'push' system in Lean production?

Accepted Answer

Pull produces only when downstream demand signals it; push produces based on schedules

Answer

In a pull system, production is triggered by actual downstream consumption, preventing overproduction; a push system produces according to forecasts regardless of real demand.

Question 2

A Lean team maps a process and identifies a 'queue' icon with 200 units waiting between two workstations. What type of waste does this represent?

Accepted Answer

Inventory

Answer

Work-in-process inventory piling up between workstations is classified as the waste of inventory, one of the eight Lean wastes.

Question 3

In value stream mapping, what does a 'push arrow' (striped arrow) indicate?

Accepted Answer

Material is being pushed to the next process regardless of demand

Answer

The push arrow in VSM shows that material moves forward based on a schedule or upstream capacity rather than downstream demand.

Question 4

Which Lean technique involves leveling both production volume and product mix over time?

Accepted Answer

Heijunka

Answer

Heijunka (production leveling) smooths out demand variation by distributing different product types and quantities evenly across a production period.

Question 5

What is the primary purpose of a 'shadow board' in 5S implementation?

Accepted Answer

Provide an immediately visible storage location and instantly show when a tool is missing

Answer

A shadow board has outlines of each tool so anyone can instantly see what belongs where and whether any tool is out of place or missing.
