Hi Robin. A resource that I keep referencing is the book Web ReDesign 2.0 | Workflow that Works by Kelly Goto & Emily Cotler, published by New Riders. It’s an excellent volume outlining the project management aspects of a web redesign project and includes many checklists and templates. It covers the technical questions that you should be asking your vendor as well as those you’ll hope that the vendor will also ask you. There is an accompanying website: http://www.web-redesign.com/where you can find more information, plus some of the templates, links and resources cited in the book.
