In a Lean enterprise, which principle describes the idea that every process step should only produce output when the downstream process requests it?
Answer: Pull system
A pull system triggers production based on actual downstream demand signals (such as kanban cards), preventing overproduction and excess inventory — a core Lean principle.
An enterprise Lean transformation team wants to eliminate waiting waste between departments. Which Lean tool is MOST directly used to visualize and quantify this inter-departmental delay?
Answer: Value stream map
A value stream map captures both value-added and non-value-added time (including wait time) across the entire flow, making inter-departmental delays visible and measurable.
Which concept in Lean enterprise thinking refers to the rate at which the market demands a product, used to synchronize production pace?
Answer: Takt time
Takt time is calculated as available production time divided by customer demand rate; it sets the heartbeat for production and helps align all processes to customer pull.
A Lean Black Belt notices that a factory layout causes workers to walk long distances between workstations. Which waste category does this PRIMARILY represent?
Answer: Motion
Motion waste refers to unnecessary physical movement by people (walking, reaching, bending), whereas transportation waste refers to movement of materials or products.
In an enterprise Lean deployment, 'yokoten' is best described as:
Answer: The horizontal sharing and replication of best practices across the organization
Yokoten (横展) literally means 'horizontal deployment' in Japanese — it is the Lean practice of proactively sharing successful improvements across different areas or facilities to multiply gains.
When applying enterprise-level Lean, a Black Belt wants to assess how efficiently the organization converts inputs into customer value. Which ratio BEST captures this?
Answer: Process cycle efficiency (value-added time ÷ total lead time)
Process cycle efficiency (PCE) directly quantifies the proportion of total lead time that is actually value-adding; a low PCE signals significant waste and improvement opportunity across the value stream.
