1. What is a typical measure of process variation on Lean Six Sigma projects?
Upper and Lower specification limits
Process center point
2. What does the Taguchi Loss Function indicate?
The amount of data loss that is embedded within a data collection process
System losses due to process variation
The magnitude of scrap and rework costs created within a process
3. Under what conditions would you likely experience no variation in the output of a process?
Variation is likely to occur before a Lean Six Sigma project – but the project should remove all variation
There is no condition where this will occur. All processes create variation at all times – just the level of variation changes
The output of a process varies when the input varies. If all input variation is eliminated, the output will have no variation
