Question 350
The project manager encounters this hybrid delivery challenge: A manufacturing project performs only end-of-line inspection and discovers expensive defects late. Which result should be used to validate improvement in the stated situation?
Explanation
Correct Answer
“Defect escape and rework trends decline with evidence of effective early checks.” is meaningful evidence for “A manufacturing project performs only end-of-line inspection and discovers expensive defects late” because it demonstrates the practical outcome of “Introduce process-quality prevention and in-process checks rather than relying only on final inspection.” instead of merely recording that work took place.
Incorrect Answers
“Load testing shows acceptable energy and performance behavior against agreed targets.” could measure performance for “A software product meets technical requirements but generates high energy use under realistic traffic.”, yet it is not direct evidence that “A manufacturing project performs only end-of-line inspection and discovers expensive defects late” has been resolved through “Introduce process-quality prevention and in-process checks rather than relying only on final inspection.”.
“Recurring defect frequency falls and corrective prevention measures are evidenced.” could measure performance for “A team repeatedly fixes the same class of interface defects without identifying its underlying process cause.”, yet it is not direct evidence that “A manufacturing project performs only end-of-line inspection and discovers expensive defects late” has been resolved through “Introduce process-quality prevention and in-process checks rather than relying only on final inspection.”.
“Production-like tests demonstrate agreed reliability and residual quality risks are accepted appropriately.” could measure performance for “A supplier claims quality because it closed all defects, but the retest environment differs from production conditions.”, yet it is not direct evidence that “A manufacturing project performs only end-of-line inspection and discovers expensive defects late” has been resolved through “Introduce process-quality prevention and in-process checks rather than relying only on final inspection.”.
