The three-circle model: why family, ownership and business keep colliding

When an owner calls because "something isn't working", they rarely know how to name the problem. They only know it's tense — between him and his son, between siblings, between the company and the family. Almost always, the root is the same: the three systems that make up a family business develop at different speeds, and no one separated them in time.

The simplest yet most powerful tool for understanding that tension is the three-circle model. It was created at Harvard in the 1980s, but we still use it in the first meeting with every family — because within fifteen minutes it turns a vague sense of unease into a clear map.

Three systems that overlap

A family business isn't "an ordinary company with a family inside it". It operates simultaneously through three systems, each with its own logic and its own rules:

• Family — a system based on belonging, loyalty and emotion. In a family, membership isn't earned; you're born into it. The rule is equality and unconditional support.
• Ownership — a system based on capital, risk and the right to decide. Here the question isn't who loved whom more, but who bears the risk and who has a right to the return.
• Business — a system based on performance, competencies and results. Here roles are earned, not inherited, and contribution is measured.

Each system is healthy in itself. The problem arises when their rules get mixed — when a business decision is made by the logic of the family, or a family matter is argued by the logic of ownership.

Most conflicts in a family business aren't a conflict of people, but a conflict of systems that haven't been separated.

Seven positions in the model

When the three circles overlap, seven possible positions arise. Every person in the story of a family business sits in exactly one of them:

1. A family member who is neither an owner nor an employee (e.g. a spouse or a child who doesn't work in the company).
2. An owner who isn't from the family and doesn't work in the company (an external investor).
3. An employee who is neither an owner nor a family member (a professional manager).
4. A family member who is also an owner but doesn't work in the company (a successor with a stake but no operational role).
5. An owner who works in the company but isn't from the family (a manager with a stake).
6. A family member who works in the company but isn't an owner (e.g. a son before ownership is transferred).
7. The founder — a family member who is at once owner and employee. In them all three circles overlap.

The value of this model is that it separates the person from the role. The same person can wear three hats — and that's precisely why conversations often go off track: a father speaks as a father, and the son hears an owner; or the son asks for a salary as an employee, and the father replies as a parent.

The model doesn't erase the fact that it's the same person — it only separates which role that person is speaking from at a given moment.

Why problems arise precisely at the overlap

The greatest tensions almost always break out where the circles overlap. A few typical examples from practice:

• Salary vs. support. The successor is paid by the logic of the family ("he's my son"), not by the market value of the role. The professionals feel it, and the successor himself is left without a measure of his own progress.
• Dividend vs. reinvestment. Owners who don't work in the company want a payout; those who run the company want to invest. Without a clear rule, this becomes a personal conflict instead of a business decision.
• Hiring relatives. People enter the business by the rule of the family (belonging) rather than the rule of business (competence) — and bad decisions are tolerated for years so as not to "hurt" the family.

You'll notice the pattern: in each case the rule of one circle has been applied in the wrong circle.

How to recognise which circle your problem comes from

Next time you feel tension, ask yourself one question: which system are we actually talking about?

• If it's about love, belonging and relationships — that's a question of the family, and it's resolved through conversation, not a contract.
• If it's about capital, risk, dividends and control — that's a question of ownership, and it's resolved through an ownership agreement and rules.
• If it's about performance, role, salary and accountability — that's a question of the business, and it's resolved through professional standards.

When a family realises it isn't arguing about who loves whom, but about which rules a decision is made by — the conversation stops being personal.

The three-circle model is only the beginning. It shows you where the problem is, but not how to solve it — that's what concrete tools are for: professionalising governance, an ownership agreement and, finally, a family constitution. But without this map, each of those tools is applied blindly.
