Plain-English definitions of every term in the Align Operating System (AOS), from Core and the five levels to the nine pillars, GET, Mastery Circle and Liz Trotter’s own frameworks.
This AOS glossary is the shared vocabulary of the Align Operating System. Owners, managers and coaches use the same words, so a weekly meeting in Olympia sounds like a weekly meeting in Atlanta.
Use the AOS glossary when a term comes up in a Mastery Circle check-in, in GET, in your AOS Diagnostic results or in one of our articles. Each entry links to the page that explains it in depth. New to AOS? Start with Core, the five levels and the nine pillars, then come back to the AOS glossary as you implement. For broader small-business terms, the U.S. Small Business Administration business guide is a helpful companion, and ISSA covers cleaning‑industry standards.
Every term in this AOS glossary comes from real work inside cleaning businesses. Liz Trotter, founder of Core Profit Builders, has been a part owner in six cleaning companies, and the Align Operating System reflects what owners and their teams need to build next.
