Does every/any company adhere consistently to that? Of course not; companies are made of fallible humans.
But how do you -ever- bind a group of people together to pull in the same direction, -especially- when it's at the expense of short term gains, for unclear long term gains? By creating a guide, a set of principles. That's what a mission/values/etc statement is supposed to be. Not just marketing bullshit, but something that helps determine what action to take. "We're gonna be the best" isn't useful, "We're going to prioritize X" is; it's a guiding star to recalibrate against. Yes, it takes someone to point out when you drift, and corrective action to be taken, but without it, you have no hope whatsoever of staying on a given course.
Instead of doing the minimal amount they had to do, they took it a step above. It would have been perfectly okay, and business as usual, to recall in Chicago, and then to do nothing. Instead they did a nation-wide recall, and didn't reintroduce the product until they had a solution to prevent it from happening again.
I don't have the case study details in front of me, but just as an aside, companies can be sued and will lose if the plaintiff can prove they were negligent; for example, not taking reasonable steps to prevent tampering.
The one I always think of as good is "Move fast and break things". Not that it necessarily is a good idea, but rather that you can quite clearly use it to help make decisions like "do we launch now to capture a transient opportunity or later to ensure full QA?"
Again, going back to the J&J case, placing their priority on their customers, their community, above their employees, and above their stockholders, meant that everyone could align in "We have to do what is safest for them, despite the cost or inconvenience to us". It would have been much easier to just issue a localized recall; they instead issued a national one. They could have pointed fingers (the addition of cyanide was, after all, not their fault); instead they took ownership over how to make their product safer. Etc.
It's not a catch all or magic bullet, but it -is- important to know, when making decisions, what to prioritize for.
