A craft survives when someone teaches the reason for the inconvenient step.

Instructions pass on more easily than reasons do, and the inconvenient step is always first to be dropped. It slows the work and looks unnecessary, so unless somebody explains what it prevents, the next hands improve it away and find out later. Craft is not really the sequence of actions; it is the understanding of why the awkward part exists. That is the fragile piece.

If you are teaching anything, explain what goes wrong when the tedious step is skipped. If you are learning, ask before deciding a step is pointless. Write the reason down, since reasons go missing faster than methods.
