Relation between specification limits and control limits.
Group of answer choices
Specification range is narrower than the control limits range.
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Specification range is wider than the control limits range
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Specification range and the control limits range overlap
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Specification range is narrower than the control limits range.
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Answer: Process is not capable
Reason: When the control limits exceed the specs limit, the probablity of errors is more and hence the process is not capable.
Specification range is wider than the control limits range
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Answer: Process is capable
Reason: A narrower control limits range reflects good capability as even if some of the data points fall out of the control limit range, it still would be under specs limit range
Specification range and the control limits range overlap
[ Choose ] Process is capable. Process is not capable. Process is borderline capable.
Answer: Process is borderline capable
Reason: Literally, the process limits are on border line as control and specs limits are the same. Even if single data point goes out of limits, the process would fail.
