I’ve been looking for answers and insight on what are the parameters used to validate that we need to revamp a product (websites, mobile apps or related services)? What symptoms we need to look at before we decide to do a redesign and revamp? and within what timeframe we need to refresh the products? is it within a year? Because UX keeps evolving and new technologies keep emerging. How do we know we need redesign, do we need to redesign whenever new design trends show up? or other competitors have already redesign their products with something new?
I would appreciate if someone can share the experiences, case or insights
