VeriqaThe drift no one
was looking at.
How an established, multi-product API manufacturer surfaced a slow yield decline that was invisible in every product — and fixed its root cause before a single batch went out of spec.
Every product looked fine on its own.
Five APIs ran on shared equipment. Across three of them — the ones sharing a single reactor line — a slow yield decline crept in, batch over batch. But each product's readings stayed comfortably within spec when reviewed alone.
Per-product review — the way every QA team works — showed nothing. The drift only existed in aggregate, where no one was looking.
“We’d reviewed each product for months and everything passed. Seeing them together changed the picture in an afternoon.”
Overlay the batches, and three drift as one.
Veriqa reasons across products, not just within them. Combine every batch into one view and three of the five — the reactor-line cohort — trace the same downward path toward the spec limit.
Fixed at the source, before any batch failed.
With the root cause named, the customer re-qualified the reactor and opened a CAPA — while every batch was still in spec. No deviation. No rejected product. No recall.
