Schein's Three-Level Cultural Model, Explained for Business Leaders

Ask ten executives to define their company culture and you'll likely get ten different answers, most describing things like open floor plans, casual dress codes, or a stated commitment to "putting people first." Those answers aren't wrong. They're just incomplete. They describe the surface of culture without touching what actually drives it.

Edgar Schein's three-level model of organizational culture remains one of the most useful tools for closing that gap, which is why it anchors a recent peer-reviewed study in Fórum Empresarial examining how ethical culture shapes diversity outcomes and competitive advantage. The model gives leaders a way to look past the visible and ask a harder question: what does our organization actually believe, and does that belief match what we say out loud?

Level One: Artifacts

The first and most visible layer of culture is artifacts — the tangible, observable elements of an organization. Office layout, dress norms, the tone of internal emails, how meetings are run, what gets celebrated in a company newsletter. Artifacts are easy to see and easy to change, which is exactly why so many culture initiatives stop here. A company can redesign its office, rewrite its values statement, and launch a new onboarding video, all without touching the deeper layers of culture that actually shape behavior.

Artifacts matter because they signal intent. But signals can be misleading on their own. A wall poster about integrity tells you what an organization wants to project, not necessarily what it practices.

Level Two: Espoused Values

The second layer is espoused values — the explicitly stated principles an organization claims to operate by. This is where most mission statements, codes of conduct, and leadership messaging live. Espoused values describe how leadership wants the organization to behave and how it wants to be perceived, both internally and externally.

The research is careful to note that espoused values are aspirational by nature. They represent intention, not necessarily lived experience. A company can espouse transparency while still operating with internal information silos. The distance between what's espoused and what's practiced is often where employees first sense that something doesn't add up, even if they can't quite articulate why.

Level Three: Underlying Assumptions

The third and deepest layer is underlying assumptions: the unspoken, often unconscious beliefs that genuinely drive decisions and behavior. These assumptions are rarely written down anywhere. They live in how people actually respond to mistakes, how disagreement is handled, and what gets quietly rewarded versus quietly discouraged.

This is the layer the study identifies as both the most important and the most difficult to work with. Underlying assumptions are slow to form and slow to shift, and because they operate below conscious awareness, they're hard to measure directly. The research flags this as a genuine limitation in ethical culture work generally: you can survey people about their stated values fairly easily, but getting an accurate read on underlying assumptions usually requires a more careful, structured approach.

Consider a company whose espoused values include "we welcome dissent," printed right there in the employee handbook. If underlying assumptions actually reward agreement and quietly penalize pushback, that espoused value will ring hollow the first time someone tests it. Employees learn quickly which version of the culture is real: the one written down, or the one they experience when they raise their hand in a meeting. Schein's model gives leaders the language to ask which version their organization actually is.

Why Alignment Across the Three Levels Matters

The real insight from applying Schein's model to ethical culture isn't any single layer — it's the relationship between them. When artifacts, espoused values, and underlying assumptions are aligned, an organization's stated ethics and its lived behavior reinforce each other, and that consistency is what employees experience as trustworthy leadership.

When the layers are misaligned, the result is a culture that talks about integrity but doesn't practice it consistently, or one that talks about inclusion while its underlying assumptions quietly favor a narrow set of perspectives. The study connects this alignment directly to diversity outcomes: ethical leadership functions as the mechanism that helps bring these three layers into closer alignment, which in turn supports more genuine diversity integration rather than diversity as a checkbox exercise.

Applying the Model as a Leadership Tool

For leaders, Schein's model is most useful as a standing diagnostic question rather than a one-time audit. Look at your artifacts and ask what they signal. Look at your espoused values and ask how closely they match daily decisions. Then look harder at the assumptions beneath both — the patterns that show up when leadership isn't being watched.

That third question is the uncomfortable one, and it's also the one the research suggests matters most. Organizations serious about building an authentic ethical culture, rather than a well-branded one, need to be willing to examine the layer they can't easily see. This is also where the model earns its keep as an ongoing practice rather than a one-time workshop exercise — culture shifts slowly, and revisiting all three levels periodically is what keeps artifacts and espoused values honest over time.
