Question

True/False: For statements 1 through 6, state true or false

From a quality perspective, a process is said to be a “capable” process if capacity (supply) exceeds customer demand.                           [ Select ]                       ["True", "Flase"]      

If a process is not a capable process, then it is better to achieve a good Cpk for this process, before achieving a good Cp.                           [ Select ]                       ["True", "False"]      

In SPC, control charts can be useful in detecting assignable or special cause variations.                            [ Select ]                       ["True", "False"]      

We want specification limits to be within control limits.                            [ Select ]                       ["True", "False"]      

Specification limits are based on a black belt’s product specifications.                            [ Select ]                       ["True", "False"]      

A delivery service that misplaces, on average, two packages per 1,000,000,000 (1-billion) deliveries is operating at six sigma level.                           [ Select ]                       ["True", "False"]      

Answer 1

1. False. As from a quality perspective, a process is said to be a “capable” process if product’s quality exceeds customer demand.
2. True that if a process is not a capable process, then it is better to achieve a good Cp for this process, before achieving a good Cpk.
3. True that in SPC, control charts can be useful in detecting assignable or special cause variations.  
4. False as we want upper and lower control limits are within the upper and lower specification limits.
5. False as specification limits are not based on a black belt's product specifications.
6. True that a delivery service that misplaces, on average, two packages per 1,000,000,000 (1-billion) deliveries is operating at six sigma level.
