LMC Performance Measurement and Lean Metrics 1 — Questions and Answers
Question 1: Which metric measures the total time from order to delivery?
- Cycle time
- Takt time
- Lead time (Correct answer)
- Downtime
Correct answer: Lead time
Lead time in Lean refers to the total time elapsed from the moment a customer places an order until they receive the finished product or service. It encompasses all stages, including order processing, production, and delivery. Reducing lead time is a key objective in Lean, as it directly impacts customer satisfaction, responsiveness, and competitive advantage.
Question 2: What does Takt time represent in Lean metrics?
- Machine efficiency rate
- Customer satisfaction score
- Rate of production needed to meet demand (Correct answer)
- Total idle time
Correct answer: Rate of production needed to meet demand
Takt time is a crucial Lean metric that represents the rate at which products or services must be produced to meet customer demand. It is calculated by dividing the available production time by the customer demand for that period. Takt time helps synchronize production with customer needs, preventing overproduction or underproduction, and ensuring a steady flow of value.
Question 3: Which tool is used in Lean to visually monitor performance metrics?
- Pareto chart
- Control chart
- Dashboard (Correct answer)
- Gantt chart
Correct answer: Dashboard
A dashboard in Lean is a visual display that presents key performance indicators (KPIs) and other relevant metrics in an easy-to-understand format. Its purpose is to provide real-time or near real-time visibility into process performance, allowing teams and management to quickly monitor progress, identify deviations, and make informed decisions. This visual management aids in continuous improvement efforts.
Question 4: What is the main purpose of using Key Performance Indicators (KPIs) in Lean?
- Increase employee workload
- Track and evaluate performance (Correct answer)
- Replace team leaders
- Analyze market trends
Correct answer: Track and evaluate performance
Key Performance Indicators (KPIs) are vital metrics used in Lean to track, measure, and evaluate the effectiveness of processes and overall organizational performance. They provide objective data on whether Lean initiatives are achieving their desired outcomes, such as reduced waste, improved quality, or increased efficiency. KPIs enable data-driven decision-making and support continuous improvement efforts.
Question 5: Which of the following best describes 'First Pass Yield' (FPY)?
- Products produced after testing
- Items shipped on time
- Units passing without rework (Correct answer)
- Returns received from customers
Correct answer: Units passing without rework
First Pass Yield (FPY) is a quality metric that measures the percentage of units that successfully pass through a process step or the entire process without requiring any rework, repair, or scrap. A high FPY indicates a robust and efficient process with minimal defects, directly contributing to reduced waste and improved quality in Lean. It highlights the effectiveness of the process in producing good output from the first attempt.
Question 6: How is Cycle Time best defined in Lean performance measurement?
- Time between customer orders
- Setup time between shifts
- Time to complete a single unit (Correct answer)
- Workforce break time
Correct answer: Time to complete a single unit
In Lean performance measurement, Cycle Time is specifically defined as the actual time it takes to complete one unit of work or one process step from start to finish. It measures the duration of the value-adding work itself, excluding waiting times. Understanding cycle time is essential for identifying bottlenecks, optimizing process flow, and improving overall efficiency.
