How Workplace Culture Is Built in Layers
Why new values don't stick and what to do about it
The short answer: Organisational culture is not one thing. It is many things, accumulated over time. The Culture Stack is a way of seeing the layers of history, habit and meaning that already exist inside your organisation, so you can work with them rather than paint over the top.
What is the Culture Stack?
The Culture Stack borrows from technology. In software, a tech stack is the collection of tools, platforms and legacy systems that sit on top of each other. Some layers are old and deeply embedded. Some are new and still bedding in. Some are crumbling but still load-bearing. Remove the wrong one and the whole thing breaks.
Culture works the same way. Every organisation has layers. The founding story sits at the base. Early leadership decisions created the next layer. Mergers, restructures, new CEOs, market shifts, crises and growth all deposited their own. Each layer carries assumptions about how things work, what matters and what happens when things go wrong.
The Culture Stack names this reality. It makes visible what most leaders feel but cannot articulate: that their organisation's culture is not a single, unified thing. It is an accumulation.
Why the layers matter
Most organisations that set out to shift culture treat it as a single entity. They write a new values statement. They run a launch event. They print posters. And within months, the organisation reverts to something that looks a lot like what was there before.
This happens because the new layer is incompatible with what lies beneath. A values refresh that declares “innovation” will not hold in an organisation whose deepest layer rewards compliance and punishes risk. The new layer sits on top. The older, stronger layers push through.
This is why so many culture efforts fail. The leaders are not working with one culture. They are working with several, layered over years and sometimes decades. When leaders can see the layers, they stop trying to paint over the top and start working with what is already there. Some layers need to be preserved. Some need to be refreshed. Some need to be carefully excavated and replaced.
What the Culture Stack looks like in practice
Consider an organisation formed through a merger five years ago. The two legacy cultures still operate underneath the new brand. Finance runs on one set of assumptions about decision-making. Operations runs on another. A new CEO arrives and announces a culture of innovation. The initiative gains traction in pockets where it aligns with one of the legacy cultures. It stalls completely in the other.
The Culture Stack explains why. The CEO is not working with one culture. They are working with at least three: two legacy layers and a new layer that has not yet integrated. The path forward is not more communication about the new values. It is understanding which legacy layers support the direction and which actively resist it.
This is precision culture work. It is slower than a launch event. It is also more likely to hold.
Where the Culture Stack connects
The Culture Stack provides the diagnostic starting point. Once leaders can see the layers, they need tools for working with them. SHAPE names the five conditions people need from their culture. GRASS makes culture visible in everyday organisational life. The Cultureshift Formula provides the mechanism for deliberate shift.
The Culture Stack appears in Shift (2023) and is foundational to Meredith Wilson's culture programs and diagnostic work with organisations.
| Layer | What to observe | What it reveals |
|---|---|---|
| Founding layer | The habits, values and norms from the organisation's earliest years | What the culture treats as given, regardless of what has changed since |
| Growth layers | Culture added during expansions, leadership changes and strategic pivots | Where incompatibilities between old and new values are most visible |
| Disruption layers | Culture shaped by restructures, crises and significant losses | Residual fear, caution or distrust that leaders often cannot explain |
| Emerging layer | The culture currently being formed through current leadership behaviour | Whether the future culture is being shaped deliberately or by default |
Try this shift
Map the layers of your organisation's culture. Which layer is the oldest one still shaping behaviour? Which is the newest? And where are the two in tension?
→ Name the layer before you try to shift it. When a culture problem surfaces, identify which layer it sits in. Surface symptoms require different responses from deep assumptions. Precision here determines whether your response sticks.
Frequently Asked Questions
How do I identify the layers in my organisation's culture?
Start with the founding story and work forward. Every significant leadership change, merger, crisis or growth phase deposited a layer. Ask long-tenured people what has changed and what has stayed the same. The things that persist despite restructures are your deepest layers.
Can you remove a cultural layer?
Layers cannot be deleted the way you uninstall software. They can be weakened over time by consistently reinforcing different behaviours. The strongest tool is leadership consistency: when what leaders model and what they tolerate both align with the direction, old layers lose their reinforcement and gradually lose influence.
What is the difference between the Culture Stack and a culture audit?
A culture audit typically measures the current state. The Culture Stack adds a time dimension. It asks not just "what is the culture now?" but "how did it get here, and which historical layers are still active?" This changes the diagnosis and the intervention.
How does the Culture Stack relate to values work?
Values work is often a new layer added to the stack. The Culture Stack helps leaders understand why that layer may or may not hold, depending on what it sits on top of. The most effective values work acknowledges the existing layers and either builds on them or deliberately addresses the tension.
