See it three times — put your policy hat on.
One client hitting the same wall is a case. Two clients hitting the same wall is a pattern worth watching. Three clients hitting the same wall is not three separate problems — it's one policy problem wearing three different faces.
The rule is simple: the third time you see the same barrier — the same agency practice, the same court procedure, the same eligibility rule tripping someone up — stop treating it as another individual case to solve and start asking what's producing it. Individual advocacy fixes the person in front of you. Systemic advocacy fixes it for everyone behind them.
When you hit three, do this:
1. Name the barrier specifically. Not "housing is hard" — the exact rule, the exact form, the exact office, the exact step in the process that failed.
2. Put it on the watch board and ask around. Log it where the team can see it, and ask colleagues directly whether they're seeing the same thing. Three that you've noticed might be thirty across the organization.
3. Raise it at the next team meeting as an advocacy target. That's where it turns from an observation into something the organization acts on.
