I originally presented WordPress Design and Development With The Client In Mind at WordCamp Philadelphia 2012. I wanted to touch on the fact that as a designer and developer in the WordPress community that we should be more active about making sure our clients are comfortable using their websites.
The biggest thing that makes a client change their website despite how nice it looks is usability. Covering your bases and asking your client the right questions helps reduce time and let you know how familiar they are with WordPress. Please listen in on my presentation and feel free to follow the Slideshare PowerPoint slides as it goes.
