Allow at least a day or two for editing shorter jobs like emails and a week or two for complex edits (and longer for books!).
Some products, such as articles and books, likely need both a substantive edit and a copy edit. Smaller, less content-dense products, such as brochures, fact sheets, and emails, may only need a copy edit. All products should be proofread once they are in their final, typeset format (i.e., the book proof read).
It is much easier (on all sides!) to edit and track changes to text in Word. Whenever possible, send Word files for editing prior to flowing them into a design template/PDF, and accept/reject all recommended changes and address all comments prior to sending to the designer.
Levels of Editing
Substantive editing (subediting)
Suggest segues when needed (e.g., between levels of headings)
Look at overall structure of piece
Is there a sufficient introduction and conclusion? Does the flow make sense?
Are references to internal items/sections treated correctly?
Check structure of and parallelism in lists
Correct subject/verb agreement
In discussions of tables/figures, ensure the text agrees with what appears in the table/figure
Apply grammar and CFA Institute style
Create a style sheet to establish decisions on hyphenation, spelling, etc.
Ensure all references have a call-out in text
Fact-check names of important people, company/organization names, titles of books and articles, etc.
