How can I justify UX processes?
How are you justifying UX effort e.g. redesigning a page to be less cluttered or just visually better appearing against numbers like click through rates and business KPIs?
An example in more detail: You want to redesign a start page und you have good evidence from user tests that people are going to like it and that it would be more usable. But you don't get the resources in your team or company to get it done. The answer you get is simply something like: "Why should we do this? It really works good and the numbers are also good. We are making good money."
Is the only way of choice to build an A/B test which will probably show that also click rates get better through an improved design.
But what about things which are simply not measurable? What if your new design is just more competitive or reflects state of the art design?
When is the point where the head of the company just has to support UX and has to say: We want to make it, even if it will not give us immediate boost in numbers?
