yup

Keep the objective in mind. What you want to end up with is a schematic,
that is laid out in a way that aids comprehension of how the circuit
works. Typically this means overall left to right functional or power

I've gone through this a few times myself. There are a few approaches.
One is to use a schematic tool like Kicad to place all the ICs first, then
add the wires and rearrange things as you buzz out the connections.
Another approach uses an intermediate step where you enter all the buzzed
out
