01 What counts as a single-point routine
A routine is single-point when one person can run it unaided and nobody else can. Not harder for somebody else. Cannot.
Two tests settle it without an argument. Could a second person start the routine from the trigger without asking a question? Could they finish it on a day the usual person is unreachable?
A routine that passes both tests is held by a role. A routine that fails either is held by a person, and the front-sheet scorer counts it in the exposure figure.
02 How they are found
Ask three people the same question: who does this when you are not here? Where the three answers name the same person, you have found one.
The holiday rota finds the rest. A routine that quietly stops happening during somebody's week off is single-point, whatever the rota says about cover.
Owners usually guess two or three of them correctly and miss the ones they do themselves. The routines an owner holds are the hardest to see and the most expensive to lose.
03 The sit-down with the holder
Twenty minutes, sitting down, away from the counter, with nothing to prove. The holder talks through the routine once while it is written, and then the sheet is read back to them.
No part of the conversation goes to you as a separate note. What the holder says ends up on the sheet or it ends up nowhere, and they are told that at the start.
The useful question is never what do you do. It is what do you check before you start. That is where the undocumented part lives.
04 In the holder's words
The sheet uses the names the holder uses. The cage, not the mobile stock unit. Out back, not the rear storage area. Correct names belong on the insurance schedule, not on a sheet somebody reads at half past eight.
Where two people call the same thing two things, both go on the sheet, one in brackets. That is how a sheet gets read by both of them.
A holder who says the sheet does not sound like them has found a fault in it, and the fault is fixed before the sheet is signed.
05 The second-reader test
The sheet is handed to somebody who has never run the routine, and they run it from the sheet while the holder stands back and says nothing.
Every question the second reader asks is a missing line. Those lines go on the sheet the same day, while the gap is still obvious.
The test is passed when the second reader gets to the end without asking anything. Until then the sheet is a draft, whatever it says at the bottom.
Running the routine badly from a good sheet is a pass. Running it well from memory is not a test of anything.
06 The week somebody leaves
By the leaver's last week the sheets are already written, signed and in use. A handover week spent writing things down is a week spent too late.
What happens in that week is narrow: the holder line on each sheet is changed from their role to the role taking it over, and the signature block is re-signed by you.
Keys, passwords and accounts are a separate list with its own sheet, because they are revoked on a day rather than handed over in a conversation.
If the week has arrived and nothing is written, the order changes. The single-point routines are written first, the rest wait, and the scope note says plainly which ones were left.
