Pace Layers

Different parts of a system change at different speeds. Trying to force alignment creates instability.

Stewart Brand introduced the idea of pace layers to explain how civilisations stay stable while still adapting. The insight: healthy systems have components that move at different speeds, and they’re supposed to.

Fashion changes in months. Commerce in years. Infrastructure in decades. Culture in centuries. Each layer has its own rhythm. Fast layers innovate and experiment. Slow layers provide stability and memory. “Fast learns, slow remembers. Fast proposes, slow disposes.”

The layers aren’t independent — they constrain and support each other. Fast layers are held in check by slower ones. Slow layers are gradually shaped by what percolates up from faster ones. Problems arise when this relationship breaks down.

Organisations have pace layers too

Quarterly targets — fastest. What you’re measuring and incentivising this cycle. Changes constantly.

Tactics and processes — fast. How work gets done day-to-day. Adjusts in weeks to months.

Strategy — medium. Where you’re competing and how you intend to win. Should be stable for years, adjusted deliberately.

Structure and capabilities — slow. Org design, talent, systems. Takes years to build, longer to change.

Culture — slower. How people actually behave when no one’s watching. Decade-scale.

Identity and purpose — slowest. What the organisation fundamentally is. Changes rarely, if ever.

Each layer moves at its natural speed. Trying to accelerate a slow layer or decelerate a fast one creates friction.

The mismatch problem

Most organisational dysfunction is a pace layer mismatch.

Treating slow problems as fast ones. Culture issues can’t be fixed with a quarterly initiative. Capability gaps don’t close with a training programme. When you apply fast-layer interventions to slow-layer problems, you get activity without change. The initiative completes, the problem remains.

Treating fast problems as slow ones. A sales execution issue doesn’t need a strategy review. A process bottleneck doesn’t require an org redesign. When you apply slow-layer interventions to fast-layer problems, you over-engineer. By the time the solution arrives, the problem has moved.

Forcing alignment across layers. The new CEO wants to change culture (slow) at the pace of quarterly results (fast). Private equity wants capability transformation on a three-year hold. M&A integration assumes everything moves at commerce speed. These timelines aren’t wrong — they’re just mismatched to the layer they’re trying to change.

Diagnosis before intervention

When you arrive in a new situation, the first question isn’t “what should we do?” It’s “what layer does this problem live in?”

A customer churn spike might be:

• A pricing issue (tactics — fast)
• A product-market fit issue (strategy — medium)
• A capability gap in customer success (structure — slow)
• A cultural indifference to retention (culture — slower)

Each diagnosis implies a different intervention with a different time horizon. Get the layer wrong and you’ll either under-invest or over-engineer.

The pattern recognition that makes experienced operators effective is often just accurate layer diagnosis. They’ve seen enough problems to know which layer they’re looking at.

Working with the layers

Respect natural speeds. Culture change takes years. Accept that. Strategy should be stable. Protect it from quarterly noise. Tactics should flex. Don’t over-systematise them.

Let fast layers experiment. The point of fast layers is to generate variety. Not every experiment needs to succeed. Most shouldn’t. What matters is that successful experiments have a path to percolate into slower layers.

Protect slow layers from fast-layer pressure. When commerce-speed pressure reaches culture-speed decisions, you get short-termism. Slow layers need insulation from fast-layer urgency. That’s what governance is for.

Change slow layers slowly. If you need to shift culture or capability, plan in years, not quarters. Consistent pressure over time beats intense pressure over weeks. The layer will resist fast change — that’s its job.

The integration problem

Mergers make the pace layer mismatch visible.

Commercial integration happens fast — pricing, contracts, systems. You can force this.

Operational integration happens medium — processes, reporting, ways of working. Harder, but manageable.

Cultural integration happens slow — values, norms, identity. You can’t force this. You can only create conditions and wait.

Synergy models typically assume everything integrates at commercial speed. When cultural integration lags (as it must), the model shows underperformance. The response is usually more pressure — which makes cultural integration slower, not faster.

The acquirers who succeed are the ones who plan different timelines for different layers.

The pace layers model doesn’t tell you what to change. It tells you how long change takes — and warns you what happens when you ignore that constraint.
