A control chart shows several points beyond the upper or lower control limits. What does this indicate?
Answer: Special-cause variation requiring investigation
Points beyond control limits signal special-cause variation, indicating the process has been affected by an assignable, non-random cause.
Which key performance indicator (KPI) directly measures the percentage of customer orders shipped complete and on time?
Answer: On-Time Delivery (OTD) rate
On-Time Delivery rate measures the percentage of orders delivered by the promised date, a direct indicator of customer service performance.
In manufacturing cost accounting, what does the term 'standard cost' represent?
Answer: The predetermined cost based on efficient operating conditions and expected inputs
Standard cost is a pre-established benchmark reflecting expected material, labor, and overhead under normal efficient operating conditions.
A plant manager wants to create visual signals that immediately indicate when a process is abnormal. Which lean concept supports this?
Answer: Andon system
An andon system uses lights, boards, or alarms to signal abnormal conditions, allowing immediate response and stopping the line if needed.
When conducting a Failure Mode and Effects Analysis (FMEA), the Risk Priority Number (RPN) is calculated as:
Answer: Severity × Occurrence × Detectability
RPN = Severity × Occurrence × Detectability, producing a score from 1 to 1,000 that prioritizes which failure modes to address first.
Which supply chain strategy involves maintaining minimal inventory and relying on frequent deliveries from suppliers to match production needs?
Answer: Just-in-Time (JIT) replenishment
JIT replenishment synchronizes supplier deliveries with production requirements, minimizing on-hand inventory and associated holding costs.
A plant manager is assessing a proposed process change using a Pugh Matrix. What is the primary function of this tool?
Answer: Evaluate and compare multiple design concepts against a reference using weighted criteria
A Pugh Matrix scores competing alternatives against a datum (reference) using weighted selection criteria to guide objective decision-making.
