What does process mapping primarily do?
*
Calculates ROI

A bank maps loan approval and finds a delay in document verification. What has been identified?
*
A financial benefit
A measurement-system error
A process gap
A project closure issue
Why is systematic data collection important?
*
It supports structured collection of relevant data
It eliminates all variation
It replaces sampling
It guarantees statistical significance
What is the purpose of sampling?
*
To obtain representative information without measuring the entire population
To eliminate the population
To replace data analysis
To avoid defining the target population
