I work for a company that works for a company that works for a company.
We have clients that are clients of clients, and may be direct clients in some other aspect.
We host services for these entities.
That is all fine until they don't pay us.

When they don't pay us, there are multiple rounds of contacting someone who will contact someone who will contact someone.
Someday.
Sometimes, someday does not arrive.
At that point, we conduct the Scream Test.
The essence of the Scream Test is:
- This thing is theoretically not needed.
- Let's turn it off.
- And see who screams?
We shut down some stuff today. Waiting on the cacophony...
Ya man. Google it. I'm not that creative. Did not make it up.
Interesting, results seem to be focused in IT as a somewhat common approach but I'm not in IT, curious it has settled there in the vernacular.
