Provide everyone with the complete design package and a date and time for a meeting. A design review is useful for giving everyone notice that this is the last opportunity to significantly impact the design. Also a design can be used to offload unpleasant decisions or to get general input on issues with no really great options. So in general wire wrap boards are a thing of the past in my world. Occasionally I will have a tech prototype build a particular circuit to ensure it works as expected.
Designs are just too complex to waste time on a wire wrap.
Larger designs should be logically partitioned If a board is too complex to be completed by one engineer it should be divided up at logical partitions of the board. Again define the interfaces. Treat it as separate designs until some point after the two schematics are combined and primary responsibility is transferred to one person.
