I'm not actually extolling their virtues as a company, just pointing out a case where a set of values led to an action that would otherwise have not happened, and which actually led to a long term benefit.

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.

That set of "values" came from the legal system: they wanted to minimize lawsuits and regulatory fines.

Actually, they were told by the FDA they only needed to do a recall in the Chicago area, and that they were not legally culpable (because of course they weren't). Their actions in no way prevented frivolous lawsuits, and they were not going to actually have any won against them for some random person spiking their product with cyanide.

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.

Let's not belabor the conversation, but I think there were more organizational factors in play than that. Most obvious, think about the damage to the brand if consumers associate it with cyanide (of all things). The only "value" at play there was organizational and career self-preservation for the people responsible for responding to the incident. I highly doubt there were any noble impulses or high-minded values involved.

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.
