Where the money goes, why, and how to recover it.
Where the ₹ losses break down across scrap, rework, complaints, warranty.
Not by frequency. The same defect can be 10× more expensive depending on disposition.
Monsoon ambient humidity directly drives gas porosity — non-linear compounding.
Bore failing the automotive PPAP requirement. Deck and Wall passing.
Operator + shift effect on defect rate.
F1 (older lining) drifts hotter; defects follow.
Monsoon as the dominant defect amplifier.
PT-C is closest to retirement threshold (cycles ≥ 800).
Dimensional non-conformance rate climbs sharply past 800 cycles — pattern replacement threshold.
Pearson correlation with binary defect indicator.
