What is the primary purpose of Heijunka in a Lean enterprise?
Answer: To level production volume and mix evenly over a given time period
Heijunka is a production-leveling technique that distributes volume and product variety evenly across a time period, preventing overburden (muri) and unevenness (mura) that lead to waste and quality problems.
How is takt time calculated in a Lean enterprise?
Answer: Available production time divided by the rate of customer demand
Takt time equals available production time divided by customer demand rate. It sets the pace at which products must be completed to satisfy demand without overproducing or under-producing.
Which Lean principle gives both machines and workers the authority and ability to detect an abnormality and halt production immediately?
Answer: Jidoka
Jidoka, sometimes called 'autonomation,' builds quality into the process by enabling automatic detection of defects and immediate line stoppage, preventing defective items from moving downstream.
Which of the following is NOT one of the eight categories of waste (Muda) recognized in Lean enterprise?
Answer: Innovation
The eight Lean wastes are commonly remembered with the acronym DOWNTIME: Defects, Overproduction, Waiting, Non-utilized talent, Transportation, Inventory, Motion, and Extra processing. Innovation is a value-creating activity, not a waste.
What is the primary role of Standard Work in a Lean enterprise?
Answer: To document the current best-known method as a stable baseline for continuous improvement
Standard Work establishes a documented, repeatable baseline for the best current method. This baseline enables teams to identify deviations, measure improvement, and sustain gains — it is the foundation upon which kaizen is built.
In a Lean enterprise, what is the key distinction between value-added and non-value-added activities when classifying work steps?
Answer: A step is value-added only if it physically transforms the product, is done right the first time, and the customer is willing to pay for it
Lean defines a value-added step by three criteria: it must physically change or transform the product or service, it must be performed correctly the first time, and the customer must care about it enough to pay for it. Steps failing any criterion are candidates for elimination.
