How many times have you ever considered that the Client (or the departments of your organization) are also the USErs of the site, app or service that you are designing? How do you approximate your projects? What happens when the UX team 'disappears' at the end of the project?
Think it twice and make your clients co-work with you. They are not the enemy: help them to understand basic UX stuff, make them work for you analyzing designing and creating the deliverables. And there are other benefits: open communication results form this approximation, learning and sharing, and more win2win relationships.
