> In my opinion, most designers’ weak spot is analysis. But we can fix that! Analysis is the main thing that separates UX from other types of design, and it makes you extremely valuable.

Agree with this. Most designers lose a lot of credibility trying to argue in favor of their design in the face of facts showing otherwise.

Although not everything needs to be objective like the shade of color of a button (See Doug Bowman and Google), but a lot of UX people ignore KPIs, or don't care to take the initiative measure them, hoping that their design performs well or depending on product managers to do it.

A/B testing seems to be the industry standard it seems, at least when making changes from in-house designers. It's becoming more a of a science, with the hypotheses based on art and design.

A good rule of thumb: If you can't give a definitive % increase in actions, conversions, etc., then you probably shouldn't be submitting the change.

Not the standard for a surprising number of very large companies or very large digital agencies.

It should be, but in my experience this is not the case.

The problem resides in the exposition: if you give your opinion, you're just telling the rest you're not sure, and that it's your viewpoint. If you instead give facts, you're telling the rest of the audience the data that drove you to that design.

I'm really tired hearing people at meeting talking and giving opinions. They're just that, they're never facts. Only facts shows the truth and facts don't need argumentation in most cases.
