Growth as a Decision System

"Growth" is one of those words everyone uses and very few people agree on.

In practice, it has come to mean very different things depending on context. In more traditional organisations, growth often sits close to revenue targets, market expansion, or M&A. In venture-backed startups, growth is frequently shorthand for "how fast can we acquire customers before the next funding round".

Neither of these interpretations is wrong, but both are incomplete.

Over the last few years in particular, growth has drifted toward being treated as little more than performance marketing. Paid social. Paid search. Optimising funnels. Chasing efficiency metrics. In parts of the UK and European ecosystem, this interpretation has become dominant.

The problem is that growth was never meant to be a channel discipline. At its best, growth is something much broader, and much harder to do well.

The Funnel Problem (and Why It Persists)

Funnels aren't useless. They're misunderstood.

A funnel is a model, and models exist to simplify reality. They help us visualise two very real problems:

Distribution: how do people first become aware of a product or brand?
Communication: how do people learn enough, over time, to feel confident trying it?

At their best, funnels help teams reason about attention, warming, and conversion. They acknowledge that some people convert quickly while others need many touchpoints. They remind us that trust is earned, not assumed.

Where funnels fail is when they're treated as reality itself, rather than a lens onto it.

As consumer behaviour has become more fragmented and non-linear, teams have tried to "fix" funnels by making them more complex. More stages. More nuance. More dashboards. But complexity doesn't make the model truer. It usually signals that the model is breaking down.

Real user journeys don't move neatly from awareness to consideration to conversion. They loop, stall, pause, restart, and cross channels unpredictably. Trying to force that behaviour into a linear structure often creates false confidence rather than insight.

Funnels describe where things happen. They do not help teams decide what to do next.

Growth as a Decision System

A more useful way to think about growth is as a decision system.

Growth is the ongoing process of making choices under uncertainty, using imperfect information, about where to focus time, money, and attention in order to create sustainable value for the business.

Every growth team, whether they realise it or not, is constantly making decisions such as:

Which lever matters most right now?
Is this a distribution problem or a product problem?
Should we focus on acquisition, activation, or retention?
Is this signal meaningful, or just noise?
Should we double down, iterate, or stop?

Funnels don't answer these questions. Judgment does.

Seen this way, growth consists of five moving parts:

Inputs – signals from the world: behaviour, feedback, data, constraints
Judgment – interpreting those signals and deciding what matters
Choices – where to allocate scarce resources
Action – shipping something into reality
Feedback – learning what that action unlocked

Actions unlock new information. New information unlocks better decisions. That loop is the real engine of growth.

But before growth decisions can happen, someone must shape what's being offered. That's where design thinking works — shaping propositions before bets are placed.

Why Leverage Matters More Than Activity

One of the most repeated decisions in growth work is not what to do, but what not to do.

Resources are always limited, even in well-funded companies. Time, focus, and attention are inputs just as real as money. The job is not to optimise everything, but to identify which levers create disproportionate impact.

This is why obsessing over micro-optimisation can be dangerous. You can split-test almost anything: button colours, copy tweaks, minor funnel steps. But the real question is always: what is the total unlockable value of the thing I'm working on?

A small pricing experiment might unlock orders of magnitude more value than months of incremental funnel optimisation. Neither is inherently wrong, but the decision about where to focus matters far more than the activity itself.

Good growth work is ruthless about leverage.

Signals of Good Growth Decisions (Before Results Arrive)

One of the hardest parts of growth is separating decision quality from outcomes.

Some of the most important signals don't arrive on the schedule teams expect. Fast metrics like click-through rates and early conversion are often the easiest to see and the least important in the long run.

I've seen channels that looked expensive and inefficient early on reveal dramatically higher lifetime value months later. In one case, a traditional, expensive channel initially looked like a failure when judged on acquisition cost alone, only to later outperform every other channel once repeat behaviour emerged.

You get signals immediately. You don't always get the right signals immediately.

Other indicators that teams are making good growth decisions, even before the results fully show up:

Execution friction decreases
Learning compounds rather than resets
Feedback themes begin to repeat
CX issues shift in nature rather than volume
Teams align more easily around next steps

Sometimes the clearest signal is simple: things start to feel easier. Not because the work is less demanding, but because the system is becoming coherent.

Signals of Poor Growth Decisions (Even When Metrics Look Good)

The inverse is just as important.

Metrics can be "good" while the business is quietly getting worse.

Low acquisition costs can mask disastrous lifetime value. Heavy incentives can attract the wrong users. Fast growth can be artificially inflated and structurally unsustainable.

Cost of acquisition is effectively modern-day rent. Platforms charge for access the way storefronts once did, and that rent tends to rise over time. Becoming addicted to cheap growth channels often creates long-term fragility.

Other common warning signs:

Over-attachment to ideas that once worked
Re-running the same approach with cosmetic changes
Inability to step back and reframe the problem
Loud or senior voices dominating confidence assessments
Obsession with one metric at the expense of the system

Frameworks don't fail teams. Misuse of frameworks does.

Disagree, Commit, Learn

Strong growth cultures surface disagreement early.

Different perspectives, backgrounds, and experiences are an asset, not a problem. Where opinions differ, the goal isn't consensus; it's clarity.

The healthiest teams practise "disagree and commit":

Bring strong opinions to the table
Test them in reality
Commit fully once a decision is made
Learn together from the outcome

Being wrong isn't the risk. Failing to learn is.

The One Thing to Remember

The world is complex. Consumers are different. No model captures reality.

Funnels, frameworks, playbooks, and tools are valuable, but they are lenses, not answers. Used together, they help teams see problems from multiple angles. Used in isolation, they create blind spots.

Growth doesn't come from finding the perfect tactic.

It comes from making better decisions, faster, together, and letting reality, not dashboards, have the final word.
