The thing about design is...

...that those, who are critical of all the ideation, post-it notes, paper sketches, workshops, prototypes and other design process stuff, are right! You don't, strictly speaking, need any of those.

The only thing you need to create a successful design, is correctly predict the future.

Most of it anyway, but especially what a lot of different people's actions and feelings will be in that future, along with correct predictions about how you, your team and your organisation will work like until then. And what the world's economy will be work like.

The thing about design is, it's just a process that approximates a shitty-but-best-version-we-have way of traveling into until you feel like you can see an angle to play between now and then.

Which sounds like the less crazy option, compared to the alternative.
