The interface between human and machine is where leverage is won or lost.
Human Experience, UI and UX combined, is the layer through which Vision becomes Direction and Process becomes outcome. It is the denominator of the equation: strengthen it and everything above compounds; neglect it and everything above is wasted.

Strong HX makes the equation usable. Weak HX makes everything above it irrelevant.
