Logos do not make brands memorable. A clear idea about who the company is for, and what it refuses to be, does. The visual identity is how that idea gets repeated until it sticks.
The brands I return to as a customer are not the loudest. They are the ones that feel the same in an email, an app and a shop, because someone decided what they stood for and kept deciding.
Once the point of view is written down, the design system almost designs itself: the palette, the type and the imagery are chosen to say that one thing clearly, and rejected when they say something else.
I document the system as a set of decisions rather than a set of files, so that whoever joins next year understands why a rule exists and can extend it without diluting it.

Memorability is a long game. A brand earns it through years of consistency, and the identity's job is to make that consistency the easiest path for everyone who touches it.
