Hi meganw welcome to the forum
I not familiar with the phrase "user journey", so I'm assuming you mean what I would call UX (user experience).
Because you said "enhance" I'm curious about what you are already doing.
Sadly, and ashamedly, I tend to only be aware of how things fit together in the context of how I experience them and have to put in effort for how others might be experiencing things. For example, I know a button near the upper left does something, its text makes sense and seems to adequately indicate what the button is for; size, color, contrast and other styling seems good. But does my prexisting understanding bias my evaluation? I fear that it does.
Anyway, tldr, what practices are you doing now that you feel you could improve on?
