The butterfly effect of business development

The butterfly effect of business development

Key takeaways

  • In every senior professional’s network there is a pathway to their next significant client. The opportunity is usually visible. The pathway rarely is.

  • Strategy often becomes a reason to wait, especially for the busy people expected to deliver it.

  • Business development behaves like a complex system. Small actions ripple out in ways no one can predict.

  • What you control is consistency and authenticity. Genuine connection is returned, mentioned and, in time, referred.

  • The hard part is the discipline. That is where firms need structure, support and measurement.

In every senior professional’s network, there is a pathway to their next significant client: a new account, or a far larger role with an existing one. Most partners and directors can name the organisation they would like to work with. What they cannot see is the route to it.

This article explains why that route is so hard to plan, why consistent and authentic action outperforms strategy in business development, and how firms can build that habit across their senior people. It accompanies our video, The butterfly effect of business development.


Where do significant client opportunities come from at the top of the market?

The firms we work with serve a broad range of clients. But at the top end, the market is small and closely connected. In New Zealand, the organisations that hold the key client opportunities are few, and many are closely held by an incumbent firm.

That changes how new work is won. A cold approach to a tier one organisation rarely gets far. A warm introduction from someone the decision-maker already trusts usually does. So the real question for a senior professional is not who to target. It is how to find a pathway they cannot see.

Why does business development strategy so often lead to inaction?

The common answer to that question is strategy, and the machinery that comes with it. Engage a consultant. Map the network. Set the KPIs. Run the firm workshop. Cascade the findings, and trust that everyone has bought in.

Each step feels like progress. Very little of it is business development.



In our experience, strategy becomes a reason to wait. The people expected to deliver it are senior, capable and almost always busy. When a plan depends on one introduction or one meeting, and that step stalls, the whole effort tends to stall with it. Meanwhile, the relationships that could have produced the next opportunity go untended.

There is a simpler point too. Experienced professionals already know who matters in their market. They rarely need a map. They need the time and the rhythm to act on what they know. We cover the wider version of this problem in why traditional sales tactics fail in professional services.

What is the butterfly effect in business development?

The butterfly effect comes from the meteorologist Edward Lorenz, who in 1972 asked whether the flap of a butterfly’s wings in Brazil could set off a tornado in Texas. His point was that in complex systems, small changes have effects no one can predict.

Business development works the same way, because it runs on people. A strategy cannot control what one person says about you to another, or whether a contact follows through on a referral. A conversation at a school event, a favour for a former colleague, or a call to a client when nothing is on the table can travel through a network in directions no plan would forecast.

That makes the outcome unpredictable. It does not make it random. The one thing you control is whether you stay consistent and authentic.

Is instinct a business development strategy?

Across hundreds of conversations with professionals, we have found the strongest business developers are rarely the strategists. They are consistent, highly competent, and they trust their instinct.

Instinct is not the absence of strategy. It is strategy, built into the daily habits of an experienced professional. A partner who has worked in a sector for twenty years carries a detailed, constantly updated sense of who knows whom, who is moving, and where they can be useful. Acting on that, week after week, is the strategy.

Why does consistent, authentic networking pay off?

Because it rests on something more dependable than any plan: human nature.

When a connection feels genuine rather than driven by an agenda, people return it. They mention you to others and, in time, they refer you. Stay consistent and that effect reaches more people. Your network grows, and the pathway that was hidden begins to reveal itself.


The research points the same way. In a study of 523 professional services firms, the Hinge Research Institute found that 81.5% had received a referral from someone who was not a client. Visible expertise and general reputation drove most of those referrals. The study is from 2015, so the exact figure will have moved since, but the principle is unlikely to have changed: much of your new work arrives through people you have never billed.



A 2022 study in Science, covering around 20 million LinkedIn users, found that new jobs came most often through moderately weak ties rather than close connections. It measured job moves, not client referrals, but it supports the same idea. The people you know a little can open doors your closest contacts cannot.

An example: Jane and the Saturday sideline

This is an illustrative scenario.

Jane is a senior partner who leads business advisory at an accounting firm. Her network is expansive: clients who trust her with their numbers, lawyers, bankers and consultants she has known for twenty years, and the parents on the Saturday sideline who run companies, sit on boards and advise the people who do.


There is one organisation Jane would like to work with, a tier one corporate. She has never met its chief financial officer. At the firm’s strategy day, it goes on the target list. A banker Jane knows has done deals with the chief financial officer, so the plan is to ask him for an introduction. Then he gets busy, and the plan is put on hold.


Jane does not put her network on hold with it. Over the next six months she stays consistent. She calls a long-standing client when nothing is on the table. She has coffee with a partner from another division. On Saturday mornings she keeps talking with another parent, who runs a small family business and will never be a significant client. Once, she helped him think through a cash flow problem and asked for nothing in return.


Then, one Saturday, Jane mentions the corporate in passing. The chief financial officer is one of his oldest friends. He offers to introduce them.



The pathway did not run through the banker the plan relied on. It ran through someone she knew a little and kept showing up for. And that referral carries something no strategy can manufacture: personal trust. The banker’s introduction would have been a favour between professionals. This one comes with a bond.


Had Jane focused only on the target, that relationship would never have formed.

How can a firm turn good instincts into consistent action?

Instinct, authenticity and consistency win over time because they cannot be faked. The hard part is doing it week after week, when billable work is due and business development is the first thing to slip.


That is where most firms lose ground. Workshops and training help, but without ongoing support, business development fades as people get busy. What works is a steady rhythm of the right conversations, with three things around it:

  • Support, so senior people have someone helping them think through who to see and why.

  • Accountability, a regular and gentle push rather than a stick.

  • Measures that track actions and the opportunities they create, so the firm can see what is working. Opportunities, not only won work, are the leading indicator.



This is what our business development facilitation programme does. We work alongside senior professionals and their firms to turn good instincts into consistent action. Not another strategy. Not another workshop. For the wider picture, read our guide to business development for professional services firms.

Frequently asked questions

What is the butterfly effect in business development?

It is the idea, taken from Edward Lorenz’s 1972 work on complex systems, that small actions ripple out in ways no one can predict. In business development, one genuine conversation can lead, through people you cannot see, to a significant client opportunity.

Is a business development strategy a waste of time?

No, but it should not replace action. Knowing which organisations matter is useful, and senior professionals usually know this already. The risk is a plan that depends on one introduction and stalls when someone gets busy. Consistent action across the whole network is what produces opportunities.

How do senior professionals win new clients without selling?

By staying in touch with their network consistently and authentically, being useful without an agenda, and letting reputation and referrals do the work. At the top of the market, a warm introduction from a trusted contact is far more effective than a cold approach.

Where do professional services referrals come from?

Not only from clients. In a 2015 study of 523 firms, the Hinge Research Institute found 81.5% had received a referral from someone who was not a client, driven mainly by visible expertise and reputation.

How do you measure business development?

Track the actions people take and the opportunities those actions create, not only the work that is won. Opportunities are the leading indicator, and tracking them shows which habits are building a pipeline.
