In a lean enterprise, which concept describes the ideal state where every process step adds value and nothing is wasted?
Answer: Perfection
Perfection is one of the five lean principles, representing the continuous pursuit of eliminating all waste so that all activities create value.
Which lean tool is specifically designed to make abnormal conditions immediately visible to everyone on the shop floor?
Answer: Andon
Andon is a visual management system using lights or signals to alert operators and supervisors when an abnormal condition or defect occurs.
A lean enterprise uses 'jidoka' primarily to achieve which outcome?
Answer: Stop production automatically when defects are detected
Jidoka (autonomation) empowers machines and workers to detect abnormalities and stop the line immediately, preventing defects from passing downstream.
When applying the lean principle of 'pull,' a downstream process signals the upstream process to produce. What system is most commonly used to implement this?
Answer: Kanban
Kanban uses cards or signals to authorize upstream processes to produce or replenish only what the downstream customer has consumed.
In lean enterprise thinking, 'takt time' is best defined as:
Answer: The available production time divided by customer demand rate
Takt time = available production time ÷ customer demand rate, setting the pace at which production must occur to meet demand.
Which of the following best describes the concept of 'flow' in lean enterprise principles?
Answer: Moving work continuously through the value stream without interruption
Flow means creating smooth, uninterrupted movement of products or information through the value stream, eliminating queues and delays.
A Black Belt maps the value stream and finds that 85% of total lead time is non-value-added wait time. What is the most likely root cause in a lean context?
Answer: Batch-and-queue processing
Batch-and-queue processing creates large inventories between steps, causing products to wait idle for most of their lead time.
