CLL Performance Metrics & Continuous Improvement 3

Question 1

In lean, what does 'First Pass Yield' (FPY) measure?

Accepted Answer

Percentage of units completing a process correctly without rework

Answer

FPY reveals how many units flow through the entire process defect-free the first time, exposing hidden rework and waste.

Question 2

What is the key difference between leading indicators and lagging indicators in lean performance management?

Accepted Answer

Leading indicators predict future performance; lagging indicators reflect past results

Answer

Leading indicators (e.g., number of improvement events) allow proactive intervention, while lagging indicators (e.g., defect rate) confirm what already happened.

Question 3

A PDCA cycle is completed, results are verified, and the improvement holds. What is the correct next step?

Accepted Answer

Standardize the improvement and apply it to similar processes

Answer

After confirming results in the Check phase, the Act phase standardizes the change to sustain gains and share learnings across similar areas.

Question 4

Which lean metric directly reflects how well a company converts raw material to finished goods without generating scrap?

Accepted Answer

Material yield rate

Answer

Material yield rate measures the percentage of input material that becomes good output, directly quantifying the waste of defects and overprocessing.

Question 5

In a lean value stream, 'dock-to-dock time' is a measure of what?

Accepted Answer

Total time from receiving raw material to shipping finished goods

Answer

Dock-to-dock time captures end-to-end throughput time across the entire value stream, revealing total lead time including all wait and process time.
