Many many years working in power plants where EVERYTHING has a 'procedure'.
Procedures that have come about due to somebody messing up.
I have my 'procedure' for setting up campsite and tearing down campsite.
Then GF checks after I am done. That is HER procedure.
And it works for US.
Do have a written check list for both procedures BUT after doing it over and over weekly we just rely on 'doing it' and that involves touch/look.
IF in the middle of one of the checks and somebody interrupts we start over with that check point.
