Organisational Design After Rapid Growth: A Practical Guide

There is a size at which most businesses outgrow their informal structures. It varies. Some organisations manage well at forty people with minimal formal design, others start to feel the friction at fifteen. But the transition is predictable enough that it is worth understanding in advance, rather than diagnosing after the fact when the symptoms have already become expensive.

What informal structure actually means ¶

In a small business, coordination happens through proximity and relationship. People know what others are working on because they sit near them, talk regularly, and share a common understanding of what matters. Decisions get made quickly because the people who need to make them are in the same room.

This works well up to a point. The problem is that it creates no record of how decisions are made, no clarity about who owns what, and no mechanism for bringing new people into the organisation without a lengthy period of informal socialisation. When the business grows quickly, those gaps become visible.

The three design decisions that matter most ¶

The first is role definition. Not job descriptions in the HR sense, but a clear articulation of what each senior role is responsible for deciding, what it is responsible for delivering, and where its authority ends. This sounds basic, but in practice it is the thing most rapidly-growing businesses have not done.

The second is the decision-making framework. Which decisions require sign-off from the founder or CEO? Which can be made at the team level without escalation? The answer to this question determines how fast the organisation can move and how much of the founder's time is consumed by decisions that should be made elsewhere.

The third is the reporting structure. Who reports to whom, and why. This is not about hierarchy for its own sake. It is about ensuring that the people who need to coordinate with each other are connected in a way that makes coordination easy rather than effortful.

The diagnostic phase ¶

Before any of these design decisions can be made well, it is necessary to understand what is actually happening in the organisation as it currently operates. This means structured conversations with the people doing the work, not just the leadership team. It means looking at where decisions are actually being made, not where the org chart says they should be made.

At Future Anchor Hub, the first two to three weeks of an organisational design engagement are spent entirely in this diagnostic phase. The recommendations that come out of it are grounded in what we have observed, not in a generic framework applied from the outside.

What good design looks like in practice ¶

A well-designed organisation is not one with a tidy org chart. It is one where the people doing the work know what they are responsible for, know who to go to when they need a decision, and are not waiting for the founder to approve things that should be within their authority to decide.

That state is achievable in most organisations, but it requires a deliberate process to get there. The informal structures that served the business at an earlier stage do not disappear on their own. They have to be replaced with something explicit.

If your business is navigating this kind of growth, the common questions we receive section covers some of the practical details about how an engagement works and what to expect.
