A lot of legacy procedures pack three or four actions into a single step, something like close the inlet valve, open the bypass, confirm pressure and notify the control room. On paper that works because an experienced operator reads it as a sequence, but in a digital workflow it means one checkbox covers four actions and you have no record of which ones actually happened.
Splitting it so each step holds one action with its own check makes the procedure easier to follow and gives you a real record of what was done. Interface does this breakdown automatically when a procedure comes in, and your team reviews the split steps before they go into the approved version.
