Your best person just appeared at the top of the shortlist for a new management role. They’re technically excellent, they know the business inside out, and they’ve been delivering at a level that everyone else aspires to. Promoting them feels like the obvious call. It’s also one of the decisions founders frequently regret, and rarely for the reason they expected.
What choice are you actually facing?
Promoting a strong individual contributor and creating a management role look like one decision, but they are two. The first is about recognition and retention. The second is about whether this person can build and sustain a high-functioning team. A Harvard Business Review analysis found that only around one in six employees are both high performers and have genuine leadership potential. The reward and the role often need to be separated.
A 2018 study by Benson, Li and Shue analysed performance data across 214 US firms and found something instructive: promoting the very best salespeople to management produced worse team outcomes than promoting slightly less stellar performers. The firms knew what they were doing. They were rewarding top performance with a management title, and accepting weaker team results as the price. That trade-off is rarely made explicit, but it plays out constantly in small businesses.
The problem is structural. Individual contributors thrive on specialist expertise, direct problem-solving and personal output. Managers need a different set of skills entirely: coaching, conflict resolution, performance conversations, and the ability to get results through other people rather than by doing the work themselves. These two skill sets occasionally overlap, but the overlap is the exception rather than the rule.
When should they stay on the IC track?
The clearest signal is energy. Someone who thrives as an individual contributor typically wants to solve the problem rather than explain it to someone else. If they consistently take work back from colleagues instead of coaching them through it, if their development conversations are about deeper technical challenges rather than team culture, and if peers describe them as “brilliant but difficult,” you likely have your answer already.
In small services businesses, the financial case for keeping a top performer on the IC track is often compelling. Research on B2B professional services firms suggests the top 20% of fee-earners commonly generate 60 to 80% of revenue. Moving one of those people into management, without a clear plan to replace their billable contribution, compresses margins quickly.
There is also the question of what progression looks like if management is taken off the table. UK firms including Monzo and GDS have documented dual-track career frameworks that allow engineers and other specialists to advance as expert individual contributors, with increasing scope, autonomy and pay, without requiring them to manage people. The titles vary, senior, principal, lead, staff, but the principle is consistent: mastery should be a credible career destination in its own right.
CharlieHR, which works specifically with UK startups and small businesses, makes the point directly: managerial roles are scarce in small firms, and using them as a default reward mechanism often leaves you with too many overseers and not enough people doing the work.
When does the promotion actually make sense?
Management can be the right move when the person is motivated by it on its own terms, not as a vehicle for a better title. The question is whether they genuinely enjoy helping others improve. Gallup’s research suggests around 10% of people have a strong natural talent for management, with a further 20% capable of becoming good managers with significant coaching and support.
The indicators to look for are behavioural. A strong candidate has already been doing elements of the role informally: mentoring a newer colleague, resolving a team tension before you heard about it, or representing the group’s interests in conversations with you without being asked. They can explain why they want to manage in terms of what they want to enable in others, not just what they expect to receive.
Structure also matters. For a management appointment to work, you need enough direct reports to justify the role (a team of three rarely needs a dedicated manager), a credible way to measure the new manager’s success on team outcomes rather than personal output, and some form of development support, whether a CIPD-accredited course, external coaching, or access to a more experienced leader. Without that structure, you’re asking someone to learn an entirely new job without a map.
Player-manager arrangements, where someone both delivers client work and manages people, can function in very small firms. They require careful expectation-setting from the outset, otherwise the individual contributor instinct tends to take over.
What does it cost to get this wrong?
A mis-placed manager creates two problems at once. You lose what your star contributor was delivering, and you gain a manager who isn’t suited to the role. For a small services firm, this shows up fast. If that person previously drove 10 to 20% of billable output or held key client relationships, the revenue effect appears in weeks. Team morale takes longer to recover.
The engagement cost is well-documented. Gallup’s meta-analysis found that managers account for at least 70% of the variance in team engagement, and that top-quartile managers are associated with 23% higher profitability compared to their bottom-quartile counterparts. A poor management appointment moves you in exactly the wrong direction. CIPD’s 2023 Good Work Index found that 28% of UK workers cite poor management as a primary cause of workplace stress, and 21% experienced workplace conflict in the previous year. Stress and conflict drive departures.
When people do leave, the replacement cost is substantial. The Institute of Directors estimates the average cost of replacing a UK employee at around £30,000, once recruitment, training and lost productivity are factored in. In a fifteen-person firm, losing two good people in a year because a management appointment isn’t working can absorb a meaningful portion of profit.
What to ask before you decide
The clearest test is a direct conversation with the person themselves. Before you make the call, ask them to describe a time they helped a colleague improve their performance and listen for whether that story energises them or is just reported as a task. Ask where they see themselves in five years: a recognised expert in their field or a leader of people. Their answer usually settles it.
A few other questions are worth asking yourself. Can you afford the transition? If this person currently drives a material share of revenue or delivery, have you mapped out how you’ll cover that gap while they’re learning to manage? What does promotion look like if management is off the table? A vague “we’ll figure it out” will not hold someone genuinely ambitious. A specific title, pay band, and expanded scope will. Is there a reversible path? Some firms trial a “lead” role with one or two direct reports before committing to full management responsibility, which can reduce the risk for both sides.
If the answers to those questions don’t come easily, the specialist track is usually the sounder default. A business that gives its best people a credible way to grow, without forcing them into roles that don’t suit them, tends to retain them and build a stronger team at the same time.
