Something I've been musing about for a few days and figure I'd suggest, if you wanted to get a better sense of forward momentum for the story you could put together a formal in-universe ranking system for agents (similar to the organizational structures of real world organizations) based on specializations, seniority, and mission clearance ratings.

Not in any way a necessity, just thought it could be fun.

EDIT: for an example, the current CIA organizational chart:

Anything you put together could be simplified of course; BOSA isn't nearly as large of an agency as the CIA.
