Q1.Two suppliers' defect rates are plotted over eight quarters.

Which supplier needs attention, and why?
- A.Hale, because its defect rate varies from quarter to quarter
- B.Renn, because its defect rate is rising steadily every quarter✓ Correct answer
- C.Hale, because its defect rate is highest in the first four quarters
- D.Renn, because its defect rate was lowest at the start of the period
Explanation
Hale moves between $610$ and $700$ with no direction, which is ordinary variation around a steady level. Renn rises in every single quarter, from $300$ to $930$ .

A single period would give the wrong answer. Looking only at Q1, Renn appears to be the better supplier by a wide margin. Looking only at Q8, Hale does. Only the trend shows that one supplier is stable and the other is deteriorating.

This is why supplier performance is reviewed across several periods. It separates a real change from the movement every measure shows, and it catches a deterioration while there is still time to act on it.
