Plain-English guides to accessibility testing — friction types, scoring, methodology, and how the SMP platform works.
Blog
Opinion, commentary, and field notes from the SMP team.
Glossary
Plain-English definitions of the words we use across the SMP platform — friction types, severity levels, scoring shorthand.
Friction Classifications
The seven categories every finding is classified into — independent of severity. The taxonomy that drives every report we publish.
Accessibility v Usability
Why we score them as two separate measures, what each one is actually asking, and how friction types and severity feed each stream.
Methodology
How we run sessions, weight findings, and review what testers experienced. The mechanics of the SMP research process.
Cohorts
Who tests with us, why their lived experience matters, and how to choose the right group for your project.
