I co-authored an article with Kate Kalcevich who is the Head of Services at Fable about accessibility testing.
How To Bake Layers Of Accessibility Testing Into Your Process introduces "layered accessibility testing" to readers.

Using the metaphor of a layered cake, Mike and Kate highlight how teams can gather the ingredients that they need to build accessible products and services.
