Why a company style guide?
Provides consistency for various internal constituencies: writers, marketing, engineering, and the like
Enforces a similar “sound” for all external publications
Reduces translation costs, contributes to globalization
Provides a shared vocabulary for indexing
Enables external groups (such as contractors, VARs, or OEMs) to contribute documentation to your package
Solves common questions once, so groups don’t each spend time answering them
