Web Redesign: Workflow That Works (Voices That Matter)
An excellent book that has a great appreciation of the trade-off inherent in any web redesign project.
It not only highlights the typical obstacles you may encounter with a client during the redesign process, but gives solid recommendations as to how to overcome these.
There is also a short section on tracking the amount of work you do vs the amount you charge the client. Here the authors give you some "tough-love" which is well worth the price of the book on its own.
