Culture
Schein's model reads culture in three layers - visible artefacts, the values people state out loud, and the unspoken assumptions underneath - and change only sticks when it reaches the third layer, not just the first.
Three horizontal bands stack up, artefacts visible at the top, assumptions buried out of sight at the base.
Reach for this when…
- A values poster campaign hasn't changed a single behaviour on the ground.
- People say the right things in meetings and do something else on the floor.
- Leadership can't explain why a new policy keeps getting quietly ignored.
How to run it
- Run a culture diagnostic to gather signal rather than relying on impressions.
- Separate the three levels: Artefacts (what's visible - the posters, the office, the rituals), Espoused values (what people say they believe), Underlying assumptions (what people actually take for granted, usually unspoken).
- Map where the current culture is creating value and where it's destroying it.
- Define the desired culture with leadership, specifically, not as adjectives.
- Name the gap between current and desired at all three levels.
- Target artefacts and leadership behaviour first - the fastest levers on the assumptions underneath.
A worked example
Situation. Ingrid Haugen runs HR for Fjord Textiles, a garment manufacturer in Bergen, Norway, where new posters reading 'we value your voice' had changed nothing about how junior staff behaved around senior managers.
Applied. Mapping the three levels showed the posters were artefacts, 'we value your voice' was the espoused value, and the actual underlying assumption - inherited from the founding family's management style - was that questioning a senior read as disrespect.
Result. The intervention moved to supervisor training and changed how senior managers responded the first time someone junior disagreed with them in a meeting. The posters stayed up, but they weren't the point any more.
The catch
The deepest layer is also the hardest to see - people are often unaware of their own underlying assumptions, so surfacing them takes real skill and time, not a workshop afternoon. Targeting artefacts alone, which is faster and more visible, is a constant temptation and rarely moves the assumption underneath.
A new poster changes the artefact layer. It doesn't touch the assumption that made the old behaviour feel normal.
