Not sure exactly what you're after. Is this an "office job" and you're looking for some kind of daily "to do" list to follow? Not sure any such thing exists. I know it doesn't at our flight department. On the flight side, we have checklists (obviously) but not sure if that's what you're after.
Maybe something that will help is IS-BAO (International Standard - Business Aircraft Operations). It's not a checklist, more a guide to establishing "best practices" (at least they are "best" in the IS-BAO publisher's opinion) in your flight department in terms of SOPs, training, maintenance, etc. If nothing else, it would be a good thing with which to be familiar.
Sorry - probably not much help.
