Sorry for the codeless post, but I am wondering how to handle a complete UI redesign for a big web product? Maybe somebody have experience and could actually determine the steps on how you would do this?
Should it be done incrementally? Should it be redesigned at once and delivered to production? What could be the steps in order to achieve this (making visual guidelines? Applying new classes?). In what smaller steps I could possibly split the tasks for the team of developers?
Would help a lot valuable insights. Thanks.
