Glossary
Explaining internal jargon & technical language
Every organization invents its own language, and when people cannot decode it, they stop asking and start guessing.
Internal jargon grows naturally. Teams coin shorthand, products get nicknames, processes get acronyms, and before long a new person needs six months just to follow a meeting. A glossary is the antidote: one place that explains what words actually mean inside this organization.
The goal is not an exhaustive dictionary. It is a living list of the terms that cause the most confusion, the ones that mean different things to different teams, and the ones that carry context a newcomer cannot be expected to have. Short definitions beat comprehensive ones. If someone can read an entry and immediately use the term correctly, it is doing its job.
Ownership matters as much as content. Assigning a team or person to keep the glossary current prevents it from becoming the outdated document everyone knows exists but nobody trusts.
