A better example would be something like this: most PhDs of UIUC in the field of Science use the same vocabulary, despite having PhD in different fields. Hence, a team of PhDs in different, adjacent fields of Science, from UIUC, might be able to both complete each other and hit the ground running faster.

Of course, adding new member(s) to such a team should not require "PhD from UIUC". Rather, the team must also be able to absorb a member and teach him the vocabulary required to collaborate and contribute effectively.

Personally, I work as a technology/security expert in a team that consists of PhD, machine-learning experts. I've been taught enough vocabulary to understand and follow the conversation and be able to contribute and feel purposeful and innovative from my - very different - perspective.
