"He's got /She's got everything it takes. He/She knows the job better than anyone."
That's often the reasoning behind a managerial promotion. And that's precisely where the problem begins.
The technical legitimacy trap
Promoting the top expert to a management position feels like a logical decision. It rewards performance. It sends a strong signal to the team. It builds on proven competence.
But it rests on a silent — and often false — assumption: that knowing how to do a job prepares you to lead those who do it.
It's not the same competence. It's not the same role. And it's not the same kind of influence.
What a title doesn't change
The new manager steps into the role carrying their expert identity. Former colleagues become direct reports. On the org chart, all is clear. In the room, no one feels it yet.
The result is predictable: they hesitate to make calls on topics they handled effortlessly three months ago as an individual contributor. They chase consensus at all costs, unwilling to strain relationships that go back years. They avoid unpopular decisions. They keep doing the work themselves — because that's still where they feel legitimate.
The team waits. Watches. Tests, sometimes without realising it.
And the manager, given no tools for this transition, improvises.
Authority is not granted, it's built
This is one of the foundational insights in LMI's programmes: managerial authority does not come from a title. It is constructed.
It is built through consistent behaviours over time: setting clear objectives, giving regular structured feedback, holding difficult decisions, communicating with transparency, genuinely investing in people's development.
These behaviours are not innate. They are not absorbed through experience alone. They are learned, with method, with structured support, and with enough time to practise them until they become second nature.
What this transition costs when it's poorly supported
A manager who hasn't found their footing creates invisible but costly friction.
Their team lacks clear direction. Decisions pile up or dissolve into vague consensus. The most autonomous people — often the most valuable — quietly disengage, starved of the framework they need to grow.
And the manager burns out, compensating through effort what they can't yet achieve through authority.
This is not a personality problem. It is a training problem.
What organisations can do differently
The expert-to-manager transition is one of the most poorly supported in business. A one-day onboarding session. A handover meeting. A few informal tips from an already-overloaded line manager. That's usually the extent of it.
What this transition actually requires is different: structured, sustained support that helps new managers understand where authority truly comes from, develop the behaviours that build it, and embed those behaviours into their daily practice.
This is precisely what LMI's programmes address — in particular through the Becoming an Effective Manager and Exercising Authority Effectively modules, which lay the foundations of the management posture and guide managers through this transformation, step by step.
