A DTC brand believed their product was competitive based on supplier spec sheets and consumer reviews. We ran a controlled DOE interaction test — varying the topsheet, ADL, and core simultaneously — and discovered that removing just one sub-millimeter layer caused absorption speed to collapse from 12 seconds to 77 seconds. The test revealed that their perceived advantage was entirely dependent on a component they had been considering cutting to reduce cost.
Cross-Component DOE Interaction Test
A single test exposed a 40% performance gap that marketing claims had been masking.

Engineering Story
Why Only CORIO
Most testing labs measure components in isolation. Our DOE protocol tests how layers interact under stress — because a diaper fails as a system, not as individual parts.
