Annual reports are complex documents subject to many rounds of changes before being signed off, ready to print. Keeping track of which changes are author's corrections and how many rounds of them were done is unproductive and doesn't enhance the process at all.
Annual reports for the OPP, Victoria, Australia are now produced using InCopy. We have changed our process from pdf markups to use InCopy so that we can provide a collaborative editing service for long documents. Now the staff at OPP can edit the content as much as they want or need to until they reach a point where they need us to get involved again to do copy fitting, or design changes or create pdfs for review.
Using a collaborative editing process means that budgets are easy to stick to, deadlines are easier to meet and clients have control of the contents – after all, why use designers to edit content into a document?
