When Is a Kitchen Sponge Mature Enough to Throw Away?

A five-level replacement ladder, and the kitchens it certifies as teaching sites

A research poster from the School of Continuous Improvement scores 192 household kitchens against a five-level sponge-replacement maturity ladder and finds attested level climbing while working-sponge age does not fall. Capability Sprints now requires Level 4 attestation, a dated card on the fridge, before a kitchen may host a placement, and display sponges appear in 41 percent of those certified kitchens.
