The question that sparked this article
A few weeks ago, someone asked me a question that made me smile.
“Can one person really deliver a consulting project? I always assumed you needed a team.”
It was a fair question. In fact, it reflects one of the biggest myths in consulting: that bigger automatically means better.
For years, many people have linked consulting with large firms, busy meeting rooms, polished slide decks and project teams spread across different workstreams. As a result, it is easy to assume that more people means more value.
However, I do not think that is always true.
Great consulting does not come from headcount. It comes from judgement.
Clients do not buy numbers
Clients do not engage consultants because they simply need more people in the room. They engage consultants because they need expertise, clarity and perspective.
They want someone who can understand the problem, ask better questions, simplify complexity and help leaders make better decisions.
That kind of value does not improve just because more consultants join the project.
In many cases, adding more people can create more coordination, more meetings and more handovers. It can also make it harder for the client to know who actually understands the issue and who owns the outcome.
By contrast, a smaller advisory model can create sharper focus. The client knows who they are working with. The consultant understands the detail. The conversation moves quickly. Most importantly, accountability stays clear.
Not every project needs a team
Of course, teams have an important role in consulting.
Large technology projects, major infrastructure programs, global transformation work and complex regulatory change often need multiple specialists. These projects involve many moving parts, technical tasks and delivery risks. In those cases, scale can help.
However, many consulting projects are different.
A sustainability strategy does not always need a large team. A governance review does not always require multiple workstreams. A climate scenario analysis does not automatically become better because more people work on it. An executive workshop does not need layers of consultants sitting behind the scenes.
Instead, these projects need someone who can understand the business, interpret evidence and turn insight into practical recommendations.
They need experience.
They need structure.
They need clear thinking.
The real work is thinking
The most valuable consulting work often happens before anything goes into a report or slide deck.
It happens when the consultant listens carefully to what the client is really saying. It happens when they notice what is missing, connect ideas across different parts of the business and identify the few issues that matter most.
For example, a client may ask for a sustainability strategy. Yet the deeper issue may involve unclear governance, poor data, weak ownership or a lack of executive alignment.
A good consultant sees that.
They do not just complete the task. They help the client understand the problem more clearly.
That is where judgement matters.
Independent does not mean limited
Another common misconception is that an independent consultant has limited capability.
In practice, experienced independent consultants often bring deep expertise and strong networks. Over time, they build trusted relationships with legal advisers, technical experts, engineers, financial specialists, researchers, designers and facilitators.
Therefore, when a project needs extra expertise, the right person can join at the right time.
This gives the client access to specialist support without paying for unnecessary layers, unused capacity or a large team structure that adds cost but not always value.
It also gives clients flexibility. The project can expand when needed and stay lean when it does not.
Technology has changed consulting
Technology has also changed what one experienced consultant can deliver.
Artificial intelligence, digital research tools, data platforms and collaboration systems now allow independent consultants to analyse information, prepare insights and produce high-quality work much faster than before.
However, technology does not replace judgement.
In fact, it makes judgement even more important.
Most organisations already have too much information. They do not need someone to collect more noise. They need someone who can identify the signal.
They need someone who can explain what matters, why it matters and what to do next.
Clients remember value
Ultimately, clients do not remember how many consultants worked on a project.
They remember whether the project helped them.
Did it solve the problem?
Did it create clarity?
Did it challenge their thinking?
Did it help leaders make better decisions?
Did it leave the organisation in a stronger position?
Those are the questions that matter.
A large team can create activity. It can create momentum, meetings and deliverables. But activity is not the same as impact.
The best consulting does not depend on how many people sit in the room. It depends on the quality of the thinking, the strength of the judgement and the usefulness of the outcome.
Bigger may sometimes be necessary.
But it is not always better.
Sometimes, the most valuable consulting relationship is simple: an experienced adviser working directly with a client to solve a meaningful problem.
So, perhaps it is time we stopped asking, “How many consultants are on the project?”
And started asking a better question.
“Who is doing the thinking?”
