SAGE Publications provides insight on what happens to your manuscript that you've just submitted.
Depending on the journal, your article will be considered by the Editor/s and/or Associate Editors and between two and four reviewers, often from the Editorial Board.

When resubmitting a paper following revisions, include a detailed document summarising all the changes suggested by the reviewers, and how you have changed your manuscript in light of them. Stick to the facts, and don’t rant. Don’t respond to reviewer feedback as soon as you get it. Read it, think about it for several days, discuss it with others, and then draft a response.
