When I was assigned this project, it existed as a desktop-only website template that was being used by GMC, Chevrolet, Buick, Cadillac, and Vauxhall. I was asked to work backwards from the mobile-first standard, and adapt the existing website to work responsively on all device sizes.
PROTOTYPING & TESTING
I designed a responsive solution without making any changes to the desktop solution, and usability tested it on mobile and tablet sizes to be sure they performed as well as the desktop solution already was.
I worked closely with the development team to implement the template design, which was handed off to OEM-specific visual designers to apply each OEM brand.
