When you are asking yourself “Why are we doing a redesign?” you are already on the right track. Your website redesign should not be about implementing new design trends, but rather how your organization can leverage a new site to meet goals and objectives.
Do you want more views, more leads, more interaction? How can you use the site to meet goals and how will you be able to keep track of how successful your site is at meeting these goals after launch? All of these are important considerations. With all the time and resources going into a website redesign, you need to have a solid business case first.
