Product, quality, engineering, support, and marketing all work on the same launch, and each team has its own words for it. One team says field testing, another says beta, and someone else says dogfooding. Agreeing on the terms saves meetings.
The Product Validation Glossary puts 168 of them in one place, from alpha and beta testing to delta testing, user research, and product development. Every entry is defined in plain language, and many list the other names they go by. Share it with every team that touches a release so everyone works from the same definitions.
