Company A Aftermarket Failure Cause Survey — Why Pro...

Product Failure Is Not Just a Customer Experience Breakpoint — It Is a Profitability Bleed Point In the depths of manufacturing, it is common to attribute failures to operator mistakes on the production line or random material defects. However, years ago, the an automotive quality department conducted a deep-dive root cause survey of aftermarket product failures. The results revealed a truth hidden beneath the surface: the majority of quality problems originate not in manufacturing, but at the very beginning of product creation — the research and development and specification definition phase. The survey found that the primary driver of product failure is inadequate requirements engineering, accounting for over 70% of failures. This means more than seven out of ten aftermarket faults were already seeded before a single line of code was written or a single drawing was drafted. The data further reveals a leverage effect between requirements investment and total project cost. When only 4% of the budget is spent on developing technical requirements, the final project cost overrun averages 120%. When this investment increases to approximately 15%, the cost overrun narrows to roughly 20%. What appears to be saving money in the requirements phase is actually borrowing at compound...
