Chaos causes medical mistakes, not incompetence.

How to "survive" an ER visit.

(and as bonus: Complexity causes 50% of all returns.)

"The main culprit isn’t incompetence but chaos: The nation’s emergency rooms are overburdened and underfunded, treating ever more patients with ever fewer resources. "You don’t want to scare the public, because hundreds of thousands of patients get cared for very well in emergency rooms every day," says Gail Warden, president emeritus of Michigan’s Henry Ford Health System, who chaired a trio of studies of emergency care released in June by the National Academies’ Institute of Medicine. "But the system is stretched, and it could be at a breaking point in three to five years."

Federal law requires that ER doctors and nurses treat everyone who shows up, regardless of ability to pay, but there has never been enough federal money to cover those costs—and that money is dwindling."

And from Complexity causes 50% of product returns.

Half of all malfunctioning products returned to stores by consumers are in full working order, but customers can't figure out how to operate the devices. Product complaints and returns are often caused by poor design, but companies frequently dismiss them as "nuisance calls.

The average consumer in the United States will struggle for 20 minutes to get a device working, before giving up.

Most of the flaws found their origin in the first phase of the design process.

This last one might be viewed as the most important. During the design of a system program or product, most of the problems with interface or use that are going to crop up are built into the system. .
