I posted about this graphic on another thread. I find the unnecessary fancy name off-putting (liberal bullshit; making something simple unnecessarily complicated) but I was intrigued by the concept.
I looked around for an alternative and came across Tom Graves who uses “SCAN” instead, this is his graphic.
Where I found this useful is as a way of thinking about the issue mariners have with written procedures. That’s almost all the mariners at Linkedin complain about - that good seamanship can’t be broken down into a series of simple steps.
But not all the problems a mariner has to solve are the same. A problem that is “simple and straightforward” can be more easily broken down into simple steps. And so forth.
Use "best practice when the third mate inspects the fire extinguisher and "good practice when voyage planning.
