Can an employee facing a real decision look at this item and know what to do? Examples from Facebook, Google, Netflix, Honda and Toyota.
Culture, in the sociological sense, is a set of norms, values, and beliefs that a group of people share and act on. That definition works as well for a company as it does for a country or a religion. The problem is that most corporate culture decks stop at listing the beliefs and never get to the part that actually matters: helping someone make a decision when the answer isn't obvious.
A good culture item cannot be ambiguous, or if it's stated at a general level, there needs to be a mechanism that makes it concrete. The test is simple. Can an employee facing a real decision look at this item and know what to do? If the answer only becomes clear after a debate about what the words mean, the item has failed at its actual job.
Take "Integrity," which appears on a large share of corporate values pages. It sounds right, and nobody would argue against it. But it doesn't guide a decision. An employee deciding whether to ship a product with a known minor flaw, or whether to disclose an uncomfortable fact to a customer, gets no direction from the word "integrity" alone, because both choices can be argued as consistent with it. A value that everyone can claim to be following, no matter what they decide, isn't doing any work.
Compare that to Facebook's early "Move fast and break things." Setting aside whatever you think of the ethics of it, the item works as a piece of corporate culture. It is not ambiguous. It gives an employee a clear answer to a real question: should I ship this code now, even though it isn't fully tested? Culture says speed matters more than polish. If something breaks, fix it after. That's a decision rule, not a mood.
Google's "Don't be evil" sits on the other side. It sounds similarly punchy, but it hands the decision back to the individual without giving them anything to decide with. What counts as evil is left entirely to personal judgment, and personal judgment varies enormously across a company of thousands of people. It doesn't refer back to a shared standard the group has agreed on. It's not surprising that Google itself moved away from the phrase, quietly replacing it with "Do the right thing" when Alphabet was formed in 2015, which has exactly the same problem in different words.
Netflix offers another useful pair. The company's actual operating rule, distilled from its culture memo, is to act in Netflix's best interest. A more customer-centric-sounding alternative, something like "do what's best for the customer," sounds nicer, but it doesn't hold up as a decision rule. A customer base of hundreds of millions of people is too diverse and too varied to point in one direction; what's best for a customer who wants more true crime isn't what's best for a customer who wants more anime, and a rule that needs reinterpreting for every individual customer isn't a rule anymore. "What's best for Netflix" works because it has a single, coherent referent an employee can actually reason about. It also tends to land in roughly the same place the customer-first version was reaching for, since protecting the brand, the product, and the service is, in the end, what's best for the customer base as a whole too. It just asks a question an employee can actually answer.
There's a second layer to this, separate from whether any single item is well written: the difference between explicit and implicit culture. Explicit culture is what shows up in training sessions and on the careers page. Implicit culture is what actually happens: the decisions management makes and the behavior that gets rewarded or quietly punished. When the two are aligned, the culture is strong, because employees see the stated values reflected in real outcomes. When implicit culture dominates and diverges from what's written down, the company's culture is weak, no matter how polished the deck looks. In that situation, the honest move is to not have an explicit culture statement at all. A company that says nothing isn't lying to its employees. A company whose actions contradict its own deck is.
Netflix's own culture materials make almost exactly this argument. They explicitly call out generic, feel-good values like Integrity as empty unless they're tied to real consequences, and point out that plenty of companies with exactly those words on the lobby wall still collapsed into fraud. Honda has built its philosophy around "The Three Joys," the joy of buying, selling, and creating, reinforced consistently enough across decades that it's genuinely part of how decisions get made, not just a plaque in the lobby. Toyota's culture rests on two pillars, continuous improvement and respect for people, and the company has gone further than most by pairing "respect for people" with a concrete practice, genchi genbutsu, going to the actual place and looking at the actual facts before making a decision. That's the kind of mechanism that turns a general value into something usable. Even Toyota's own brand messaging reflects the same internal direction: "Fun to Drive, Again" wasn't just an ad campaign, it was a public restatement of what the company was optimizing for, at a moment when it would have been easy to let efficiency crowd out everything else. It also wasn't just messaging from the top. Akio Toyoda backed it by example, racing under the pseudonym Morizo in endurance events since 2007, founding what became Gazoo Racing, and personally test-driving development cars to give the feedback that shaped the GR Yaris, the GR Corolla, and the revived Supra and 86. When the person running the company is also the one thrashing prototypes around a racetrack and insisting the results get built, that's implicit culture doing the same work as the slogan.
None of this means culture decks need clever slogans. It means every item on one needs to survive a simple test: hand it to an employee facing an ambiguous decision, and see whether it actually tells them what to do. If it doesn't, it's not culture. It's decoration.
