I like the article because it's very similar to the workflow that I developed while working on my first project after quitting my last job. One thing that I would add to "Be Explicit About Your Goal" is that it should be about both your goal and the user's goal. Otherwise it's very easy to hit blind spots that both you, another person, or AI will miss because of bias.

A small related rant is that many large companies with a dedicated team that works on design system don't seem to actually care much about UX. It feels demoralizing because sometimes it feels like many people are just using UX to push some other agenda.
