A leadership vacuum is not necessarily about a leadership position standing empty. In practice, it arises when the business lacks clear decision-making power, direction or mandate – even though the roles are formally filled.
For the board, this represents a significant but often underestimated risk. Many organisations appear to carry on as normal, but without any real control. Over time, this can have consequences for value creation, pace and internal culture.
Typical situations in which a leadership vacuum arises:
Between an outgoing and a new CEO
When someone in the management team leaves suddenly
During mergers, acquisitions or changes of ownership
When a leader is in place, but without a clear mandate or the capacity to lead
A leadership vacuum is characterised by an absence of real control, not necessarily an absence of people. It arises when:
decisions are postponed
responsibility becomes fragmented
priorities become unclear
In such situations, power often shifts informally downwards or sideways in the organisation. Middle managers and specialists make decisions they are not equipped to make, or choose to wait. The result is a slower pace and greater risk.
This is challenging for the board, because the vacuum is rarely reported explicitly – it is only noticed once the consequences become visible.
A common mistake is to underestimate the time dimension. Many boards assume that a temporary vacuum is manageable for a few months. Experience shows otherwise.
After as little as 6–8 weeks without clear leadership, you often see:
strategic decisions being postponed
a weaker ability to deliver
growing internal uncertainty
After 3–6 months, the consequences can become structural:
loss of key expertise
weakened trust in management
a slower pace of change
A leadership vacuum is therefore not a neutral state. It is an active risk phase.
Most boards monitor key financial and operational figures. The effects of a leadership vacuum are far harder to quantify – and therefore easier to overlook.
Common consequences include:
reluctance to make decisions and a culture of consensus
competing priorities within the organisation
informal power structures
an increased burden on individuals
Over time, this can weaken both performance and culture. For owners, it can also affect how attractive the company is in the capital markets.
The board has a clear responsibility for the sound organisation and management of the business. This includes ensuring that the company has real leadership capacity at all times.
A leadership vacuum can put pressure on:
the board’s duty of supervision
its responsibility for risk management
long-term preservation of value
This does not mean that the board should step into day-to-day operations, but that it must take action when leadership capacity is insufficient.
When faced with a leadership vacuum, recurring patterns often emerge:
‘We’ll share out the responsibility for the time being’
→ often leads to confusion and internal friction
‘This will only last a short while’
→ recruitment often takes longer than planned
‘HR will follow up’
→ HR can support, but cannot replace operational leadership
These solutions may work in the very short term, but they rarely address the core problem: a lack of decision-making power.
In many situations, boards choose to use interim management as a deliberate tool to ensure continuity.
An interim manager is characterised by:
a fast start
a clear mandate
experience of transition and change situations
Interim management is often used:
after sudden leadership departures
during transformation or restructuring
as a bridge between two permanent leaders
This makes interim management an effective way to reduce risk in critical phases.
It is important to distinguish between a temporary and a permanent need. Interim management does not replace long-term leadership, but creates room for manoeuvre.
By securing stable leadership during transition phases, the board can:
carry out a more thorough permanent recruitment
reduce the number of bad hires
ensure continuity in strategy and operations
This is a sign of professional governance – not a stopgap.
A key question for many boards is which solution to choose. The answer depends on the situation.
Interim management is suitable when pace, uncertainty or complexity is high
Permanent recruitment is right when the business is ready for long-term anchoring and continuity
The most mature businesses use both tools – at the right time.
The board’s most important responsibility is to ensure that the business has, at all times:
clear leadership
decision-making power
momentum
Ignoring a leadership vacuum can be costly. Dealing with it early is good ownership governance and good business management.
A leadership vacuum arises when the business lacks real decision-making power and clear leadership, even though leadership roles are formally filled. It can be caused by temporary arrangements, an unclear mandate or a lack of capacity in the leadership role.
Because it can lead to delayed decisions, informal power structures and a reduced ability to deliver. Over time, this can affect value creation, organisational culture and the board’s responsibility for sound governance.
Experience shows that consequences often appear after as little as 6–8 weeks. After 3–6 months, a leadership vacuum can lead to structural problems such as the loss of key expertise and weakened trust within the organisation.
The board should consider interim management when:
a leader leaves abruptly
the business is going through transformation or uncertainty
recruiting a permanent leader will take time
there is a need for fast decision-making
Interim management is then used as a temporary, risk-reducing measure.
An interim manager is engaged for a limited period with a clear mandate, often during a transition or change phase. A permanent leader is appointed for long-term leadership, culture building and continuity. Both roles are important – but at different times.
No. Interim management does not replace permanent recruitment, but it can ensure stability and progress while the board carries out a thorough and sound recruitment process.
The most commonly used interim roles are:
interim managing director (CEO)
interim CFO
interim COO
interim CHRO
These roles are often used in periods of change, growth or increased complexity.
By securing stable leadership during the transition phase, the board has more time to define the needs, mandate and profile for the permanent appointment. This reduces the risk of hasty or wrong decisions.
In a full-service firm, interim management, permanent recruitment and advisory services are seen as complementary tools. The aim is to choose the right solution based on the situation of the business – not to favour one model.
