Large jobs like startups and turnarounds often have several operators working different sections of the same procedure at the same time, which paper handles badly because there is only one copy and progress lives in people’s heads or on the radio. The result is people waiting on each other without knowing whether the step they depend on is actually done.
A digital procedure should let different people take different sections, show everyone the live status of the whole job and make it clear when a step one person depends on has been completed by someone else. That shared view is what lets the work move in parallel safely instead of either running slowly in sequence or running in parallel without anyone really knowing the state of the job.
