That said, the critical plane flying and ground handling stuff (like loading cargo for proper balance) is well practiced and understood enough to run fine with ad-hoc paper records albeit it would reduce operational tempo. It's putting the right luggage in the right place, making sure the right plane gets its poo pumped, making sure the cleaning crew knows what to do and where to go, recording maintenance needs and activities on anything that doesn't fly, etc, etc that doesn't have redundancy or good fallback plans or people/managers who understand how their jobs fit into the context well enough to improvise effectively and even if they could the B rate people you had design all your corporate process didn't account for that sort of stuff so people would be risking their jobs if they couldn't do sign offs on the company ipads and whatnot.
