A procedure with thousands of steps is only usable if the operator can always tell where they are, what is done, what is next and who else is working on it. Long lists without structure become just as hard to follow on a screen as they were on paper, and sometimes harder because you lose the sense of the whole document.
What helps is clear sections, one action per step, progress that is visible at a glance and the ability to jump to any section without losing your place. Delivering the procedure step by step on mobile, which is how Interface does it, keeps the operator focused on the current step while the full structure stays available when they need it.
