Editing

Checking the draft to see that it satisfies the requirements of good English and the principles of business writing. Unlike revision, which can produce major changes in meaning, editing focuses on the surface of writing.

Revising

Making changes in the draft: adding, deleting, substituting, or rearranging. Revision can be changes in single words, but more often it means major additions, deletions, or substitutions, as the writer measures the draft against purpose and audience and reshapes the document to make it more effective.
