UX is beyond the interface
Would you rather celebrate a milestone victory with colleagues over coffee, or fumble against a deadline that's approaching like the Orient Express? What separates the two scenarios is good or bad UX.
UX appears to be a screen-only affair, but its real magic lies beyond the confines of the four corners. Good UX also betters the surrounding environment. For example, a well-designed code review tool not only makes SDLC smoother, but can improve the team's morale, the product's quality, and the company's reputation. And UX is not just applicable to software.
Consider a keynote that you're addressing to a full auditorium. Features can inform the bullet points on your presentation. But your vision determines your audiences' reaction. And it's the vision that should drive your speech, not the features.
