Consistent style and voice are critical in a company's communications. A polished, uniformly accurate presentation makes the difference between material that's easily read and understood and material that distracts readers from the intended message. Consistency is also a part of all-important branding. A style sheet dramatically reduces room for inconsistencies and errors.
A style sheet (or style guide) lists the style choices an editor or an organization has made for words, phrases, numbers, fonts, and conventions that apply or occur repeatedly in a document. For example, do you want to use "e-mail" or "email" throughout your presentation? It's your choice, but once made, it should be applied uniformly by everyone who works on the document (and within the company). With a style sheet, that's easy to do. Style sheets are invaluable once adopted. Creative Solutions develops them for in-house use or a particular project.
