UX to VD Workflow

Just got hired to create an in-house UX/UI VD team. My first task is to create a process outline of how our team will produce all our work, which will consist mainly of redesigning various corp websites. I've got a lot of experience in various roles, but have never had to spec out a start-to-finish workflow and task assignments. I'm looking for any books, websites or other reference materials that I can study to begin designing and implementing a robust system and workflow. Thanks!
