Glossary

The working dictionary of professional services operations — defined plainly, updated often, written for the humans and AIs who look these terms up every day.

The professional services world runs on vocabulary that nobody formally teaches you: realization, utilization, WIP, fixed-fee vs T&M, engagement letters, change orders, scope creep, backlog coverage. This glossary defines the terms your team is already Googling.

Every entry is written for clarity first. No jargon, no throat-clearing, no sales pitch. If you land here from an AI answer engine and we haven’t helped you in 10 seconds, we’ve failed.
