Hiring or promoting a manager: what criteria should you look for?

Hiring an external manager or promoting an internal team member: in either case, getting it wrong is costly.
A poorly hired manager can disorganise a team, undermine performance, and erode trust rapidly. A poorly promoted manager can lose their bearings, struggle to establish legitimacy, and create tensions in the very environment where they previously excelled.
In both situations, the decision is rarely without consequence.
It affects a team, a level of performance, a working climate — and sometimes the retention of key people.
The real question is therefore not simply: has this person managed before?
It is rather: what behaviours will they adopt when the team needs clarity, feedback, decisions, and support?
This is where managerial assessment becomes genuinely useful.
Hiring or promoting a manager is not simply a matter of validating experience, professional expertise, or a positive impression in an interview. It is about identifying the behaviours that will enable a person to help a team succeed in a specific context.
Two different decisions, the same risk of error
Hiring an external manager and promoting an internal one do not raise exactly the same questions.
In external recruitment, the risk is often being reassured by visible signals: a job title, a well-known employer, similar experience, a confident presence, a well-constructed management narrative.
The candidate has already managed. They know how to speak about leadership, transformation, engagement, and collective performance. They may have led comparable projects. Their career history inspires confidence.
But that experience does not always indicate how they will adapt to your culture, your standards, your managers, your teams, and your internal constraints.
In an internal promotion, the risk is different.
You know the person. You know their results, their reliability, their commitment, their expertise. They have often earned the trust of their peers and their line management.
But what made them individually successful does not always guarantee managerial success.
A high-performing team member may struggle to delegate. A recognised expert may want to retain control of key files. A highly reliable person may find it difficult to address performance issues, make difficult calls, or manage tensions.
In both cases, the trap is the same: making the decision based on what is reassuring, rather than on what genuinely predicts success in the role.
Criterion 1: the ability to set a clear framework
A manager’s first responsibility is to create clarity.
This may seem straightforward, but it is one of the most structurally important managerial competencies. Teams perform better when they understand what is expected of them, why it matters, what the priorities are, and where the boundaries of decision-making lie.
An effective manager does not simply pass on objectives. They translate expectations into concrete reference points.
They clarify priorities. They define responsibilities. They make the rules of engagement explicit. They help each person understand how their contribution fits into the wider picture.
In an external hire, this criterion allows you to assess whether the candidate can quickly take on a structuring role within a team they do not yet know.
In an internal promotion, it allows you to verify whether the team member can shift from an execution mindset to a management mindset.
The signals to look for are concrete: can the candidate explain how they set priorities? How they communicate an expectation? How they respond when a team lacks direction? How they avoid the ambiguity that leads to misunderstandings?
A manager who fails to provide sufficient clarity often leaves the team to compensate on its own. The most autonomous people cope. Others proceed without direction. And tensions emerge when implicit expectations are discovered too late.
Criterion 2: the quality of feedback
Feedback is one of the most revealing managerial acts.
It demonstrates the ability to recognise achievement, address shortfalls, support progress, redirect without demotivating, and accompany without being patronising.
A good manager does not simply say what is or is not working. They formulate a response that is useful, precise, and action-oriented.
This criterion matters particularly because many managers avoid difficult feedback. Some wait too long. Others give vague comments. Others still redirect too harshly or turn feedback into personal judgement.
In an external hire, it is worth exploring past situations: how did the candidate support a team member in difficulty? How did they handle a drop in performance? How do they give feedback to a senior profile, to a junior, or to someone who is sensitive to criticism?
In an internal promotion, you need to assess whether the person can change their posture towards colleagues who were formerly their peers. Giving feedback to a former colleague can be uncomfortable. Addressing the performance of someone you once worked alongside at the same level requires genuine relational maturity.
The quality of feedback therefore reveals more than a communication skill. It shows the ability to hold a framework while preserving the relationship.
Criterion 3: the ability to genuinely delegate
Delegation is frequently cited as an obvious managerial competency. In practice, it remains one of the most difficult to put into action.
Delegating does not simply mean distributing tasks.
It means trusting others, sharing the right level of information, accepting that someone else may approach things differently, monitoring progress without over-controlling, and leaving enough space for people to learn.
This is a decisive criterion in internal promotions.
A team member promoted into management may remain attached to their former expert role. They know the files, they work quickly, they want to ensure quality. As a result, they may take back control too readily, correct constantly, or hold onto sensitive matters themselves.
In the short term, this feels reassuring. Over time, it limits the team’s autonomy.
In an external hire, delegation allows you to assess the candidate’s real management style. Do they delegate to empower, or simply to redistribute the workload? How do they track progress? How do they respond when a team member does things differently? What do they do when a mistake occurs?
A manager who delegates well does not disappear. They establish a framework, support capability development, and adjust their level of oversight according to each person’s autonomy.
Delegation therefore reveals something essential: is this manager trying to remain indispensable, or to make their team stronger?
Criterion 4: managing tensions
A manager is not only assessed when everything is running smoothly.
Their true posture is revealed when tensions arise: disagreements, disengagement, conflict between two team members, misalignment with senior management, pressure on results, a sense of unfairness within the team.
This is often where the gap becomes clear between a manager in theory and a manager who is genuinely effective in practice.
Some avoid tensions. Others address them too late. Some try to keep everyone happy. Others impose a decision too quickly without listening sufficiently.
Managing tensions requires a careful balance: listening without being absorbed, deciding without being heavy-handed, holding a framework without closing down dialogue.
In an external hire, it is worth asking the candidate to describe a specific conflict situation — their exact role, the decisions they made, and what followed.
In an internal promotion, this criterion helps identify whether the team member will be able to manage a new kind of distance from their former peers. Legitimacy is not built on expertise alone. It is also built through the ability to handle difficult matters with fairness.
A manager who cannot manage tensions often allows problems to migrate elsewhere: disengagement, unspoken grievances, cliques, turnover, and a loss of trust.
Criterion 5: suitability for the team context
There is no single model of a good manager.
A manager may succeed with an experienced, autonomous team yet be less well-suited to a junior team that needs close guidance. They may excel in a period of transformation yet feel less comfortable during a phase of consolidation. They may perform strongly in a direct culture yet encounter difficulties in a more collaborative organisation.
This is why managerial assessment must always take context into account.
The right manager is not simply the one who possesses strong general qualities. They are the one whose behaviours, motivations, and working style are aligned with the team’s real needs.
For an external hire, this means looking beyond past experience. You need to understand in what environment the candidate has succeeded, with what type of team, at what level of autonomy, under what management style, at what pace, and under what constraints.
For an internal promotion, it means assessing the shift in posture that will be required. Will the person be managing a team they already know? Leading former peers? Driving a transformation? Managing rapid growth? Rebuilding a fragile team climate?
The criteria will not be the same.
Assessing contextual suitability helps avoid a common mistake: searching for an “ideal” manager instead of finding the manager who is right for the role, the team, and the moment the organisation is in.
How to make these criteria more objective
To make a recruitment or promotion decision more robust, several sources of information need to be cross-referenced.
A structured interview allows each candidate to be assessed against comparable criteria. It reduces decisions based solely on a positive impression or strong interpersonal ease.
Role-play exercises allow behaviours to be observed in realistic conditions: giving feedback, arbitrating a tension, prioritising under uncertainty, responding to a team member in difficulty.
Psychometric assessments shed light on working styles, motivations, relationship to others, stress management, decision-making, and adaptability.
360° feedback can also be useful in the context of an internal promotion, particularly to understand how the person is currently perceived in their interactions.
Finally, matching against the role’s success criteria helps place the results in perspective. The goal is not to find a perfect score, but to identify areas of strength, gaps to address, and the conditions under which the person is most likely to succeed.
The decision remains human. But it becomes clearer, better substantiated, and more consistent with the real context.
Hiring or promoting a manager means preparing for their success
A management decision should never stop at choosing a profile.
Hiring or promoting a manager also means anticipating the conditions for their success: their priorities, their areas of vulnerability, their support needs, and the competencies to develop in the first months.
This is especially important for first-time managers or team members promoted internally. The person is not simply changing their job title. They are changing their posture.
With the right criteria, the organisation is not searching for a perfect manager. It is identifying the best possible alignment between a person, a role, a team, and a context.
And it is that alignment that transforms a management decision into a genuine lever for performance.
