A new engineer's mental model of regulatory affairs is usually one of two things: the department that says no, or the people who file the paperwork once the real work is done. Neither is accurate, and both create friction a fifteen-minute conversation could have prevented — friction that shows up months later as a design change nobody told you about until it already shipped.
Fix the mental model before you fix the process
Regulatory affairs doesn't invent the requirements a product has to meet — it translates external ones, and owns the file that has to survive an inspection or an FDA review later. That's a different job than either misconception implies, and the difference matters practically: a colleague who thinks you say no is going to avoid you until a decision is already made, and a colleague who thinks you just file paperwork is going to assume there's nothing for you to weigh in on until the filing itself. Both habits mean you find out about a change after it's real. Naming the actual relationship — described at more length in how regulatory affairs works with R&D — is worth doing explicitly and early, ideally before the first regulatory hire has been in the building long enough for the wrong model to calcify.
Teach the one dependency that actually matters
Skip the tour of the department and go straight to the dependency that changes how someone works with you day to day: under 21 CFR 820.30, a design change has to be documented, reviewed, and verified as part of the design history file — which means a change made informally in a sprint and shipped without that record isn't just a process gap, it's a gap in the file a reviewer or an inspector can ask about later. The ask that follows from this is specific and easy to remember: tell regulatory before a design change ships, not after, so the record can be built alongside the decision instead of reconstructed once it's already out the door. One real example lands harder than the regulation itself — a change that had to be walked back, or a submission that had to be amended, because the file didn't reflect what the team actually built.
Where people get stuck
Leading with the org chart or the review process
Nobody outside regulatory affairs needs to understand how a submission gets reviewed internally. They need to know what changes for them — one dependency, not the whole department.
Presenting the job as a yes/no service desk
Framing the relationship around approval reinforces the exact misconception the session is meant to fix. The ask is to be looped in early, not asked for permission.
Never repeating the session
The mental model resets to default with every new hire who missed it. A short repeat as the team changes is worth more than a polished one-time deck nobody keeps.
A session like this doesn't make a colleague a regulatory expert, and it isn't supposed to. It changes one habit — getting looped in while a decision is still open — and that one habit is worth more to how the file actually looks later than any amount of process documentation nobody reads.
