Senior appointments bring proven capability into an organisation. Turning it into performance depends on how well the leader understands the organisation they enter, and how deliberately the organisation supports the transition.
Every senior appointment is a significant organisational investment. Boards and CEOs devote considerable time to selecting a leader with the experience, judgment and track record to create value. Yet leadership effectiveness is not imported with the appointment.
Why do some experienced leaders establish themselves quickly, while others take much longer to make the impact everyone expected?
Capability alone does not explain the difference. Leaders transition faster when they understand how people make decisions, build trust and exercise influence and when the organisation deliberately makes those dynamics visible.
“Leadership capability belongs to the leader. Leadership effectiveness is created through the interaction between the leader, the executive team and the organisation.”
The appointment is only the beginning of the investment
A new executive may arrive with a strong track record and a clear mandate. But every senior appointment reshapes the executive team: members build new relationships, reset expectations and test how they make and execute decisions. When leaders leave expectations unclear, apparent agreement can conceal different interpretations. People revisit decisions outside the room, slowing delivery. When leaders set explicit expectations and encourage candid feedback, the team surfaces differences earlier, upholds decisions and executes more consistently.
That transition begins before the leader’s first day. As SMG Executive coach Janet Horton observes, “The expectation clock starts the moment you are named for the role.”
From the announcement, colleagues and stakeholders begin forming views about what the appointment will mean and how quickly change will come. If communication and transition support wait until day one, an expectation gap can open before the leader formally begins. Drawing on Michael Watkins’ The First 90 Days, Janet also emphasises the importance of securing small, early wins. They turn expectation into confidence, build momentum and create a sense of excitement about what may be possible.
The commercial issue is not only whether the organisation appointed the right leader, but how quickly the leader and executive team become effective together.
Experience is the starting point, not the whole transition
Den Hartog and De Hoogh’s 2024 review of cross-cultural leadership found that some leadership attributes travel across cultures, while expectations of leaders and interpretations of their behaviour remain context-dependent. This reinforces a broader principle in executive transitions: leaders may carry proven capability into a new environment, but they and the organisation must build effectiveness together.
Leaders entering a new organisation lack the knowledge that colleagues have built through shared history: which relationships influence outcomes, how people express disagreement, where they make decisions, which behaviours earn trust and why previous attempts at change succeeded or failed.
Internal appointees face a different challenge. Familiarity can create blind spots: leaders may assume they understand the broader system, while colleagues continue to view them through the lens of their previous role. Both sides must reset their assumptions if the leader is to establish themselves in the new role.
When Satya Nadella became Microsoft CEO after more than two decades within the business, he made learning, empathy and collaboration central to the company’s cultural reset. His experience inside Microsoft mattered, but it did not remove the need to understand the organisation from a different position and reshape how people worked together. Microsoft itself describes the cultural shift under Nadella as a move from internal competition and silos towards greater openness and collaboration.
“The expectation clock starts the moment you are named for the role.” Janet Horton, SMG Executive coach
The most effective leaders retain the strengths and experience behind their appointment while becoming curious about the culture, history and assumptions around them. As SMG Executive coach Charles Weiser observes, the transition expands the leader’s repertoire rather than requiring a new leadership style. It broadens how they communicate, influence and act so their capability is effective in the new environment.
Learning how the organisation really works is part of leading
Charles, who has led across Europe, the Americas, Asia-Pacific and Australia, describes organisations as having two operating systems. The formal system is visible in structures, roles and governance. The informal system lives in trusted advisers, respected experts, long-standing relationships and unwritten expectations.
Newly appointed leaders usually grasp the formal system quickly. The informal system is harder to see, yet it often determines whether leadership intent becomes action. Agreement can be mistaken for alignment, politeness for trust and compliance for commitment. A leader can believe change is moving when the organisation has not decided to move with them.
“Learning is real work.” Charles Weiser, SMG Executive coach
At SMG, we see curiosity as a leadership discipline. Charles describes it simply: “Learning is real work.” Listening, observing and testing assumptions are part of leading from the outset. As Janet notes, questions do more than gather information. They build trust by recognising the knowledge already within the organisation and inviting people into the transition. This disciplined curiosity strengthens judgment and helps the leader understand where change will be supported, where it will be questioned and what will be required to turn intent into committed action.
Leadership intent must survive translation
Understanding the system only creates value when it changes how leadership is exercised. Mark Devadason, an SMG Executive coach and former CEO with three decades of leadership experience across Asia and Australia, has seen proven behaviours interpreted differently in a new environment.
Speed and directness may signal clarity in one environment but feel forceful in another. Open debate may work where challenge is expected but can silence valuable perspectives where hierarchy, language or previous experience makes people cautious. The leader’s intent may be sound and still fail to land as intended.
For Mark, leadership communication should be judged by what others can understand, contribute to and act on. As he puts it, “Communication needs to be slowed down and designed for the listener, and not the speaker.” In practice, this can mean allowing time for reflection, using smaller groups to invite contribution and actively drawing out views that might otherwise remain unspoken.
It also means recognising that the most confident person in the room does not necessarily hold the best insight.

Leadership transitions work best as a shared responsibility
Much of the commentary on executive transitions concentrates on what the newly appointed leader should do: listen, build relationships, understand the business and establish priorities. Each matters, but leadership effectiveness is not something leaders create alone.
The newly appointed leader must bring curiosity, test assumptions and adjust how their capability is expressed. The Chair and Board must continue their stewardship beyond selection by clarifying the mandate and stakeholder expectations, sharing the history behind important decisions, and remaining available as a sounding board. The Board should look for evidence that important decisions are made and held, the executive team aligns around priorities and agreed outcomes are delivered, rather than equating early activity with effectiveness.
A CEO appointing an executive carries the same responsibility: to be explicit about expectations and help the executive understand how the organisation works in practice, rather than leaving them to work it out alone.
For the executive team, the appointment requires a reset of working relationships, decision rights and expectations, so the mandate becomes collective action rather than the agenda of one individual.
The CHRO can support that reset by explaining the organisation’s history, identifying critical relationships, providing candid feedback and aligning transition support, including coaching or mentoring where useful. The executive team must remain open to the perspective the leader was appointed to bring. Shared responsibility is not about teaching the leader to fit in while the organisation remains unchanged.
Turning leadership capability into organisational performance
A significant appointment creates the potential for organisational value, but the appointment alone cannot realise it. That requires a clear mandate, aligned sponsorship, candid feedback and deliberate transition support. These conditions help the leader understand the organisation and enable the executive team to align around the priorities and change the appointment is intended to advance.
When organisations apply this support consistently across significant appointments, they build an organisational capability rather than assembling transition support case by case. Leaders and executive teams make clearer decisions, hold their commitments and execute with greater consistency. This reduces transition risk and shortens the path from appointment to performance.
Strategic advantage lies not simply in appointing accomplished leaders, but in creating the conditions in which leaders and executive teams can perform, create organisational value and lead meaningful change.

Frequently asked questions
What is the difference between leadership capability and leadership effectiveness?
Leadership capability is what a leader brings: their experience, judgment and skills. Leadership effectiveness is how well that capability translates into aligned decisions, committed action and results. It is created through the interaction between the leader, executive team and organisation.
Why doesn’t proven leadership capability always translate into a new role?
Past success does not give a leader immediate knowledge of how a new organisation builds trust, exercises influence, makes decisions or responds to change. Even internal appointees face a transition: familiarity can create blind spots, while colleagues may continue to see them through the lens of their previous role.
When does an executive transition begin?
The transition begins when the appointment is announced, not on the leader’s first day. From that moment, employees and stakeholders start forming expectations about what the appointment will mean. Early communication and transition support help manage those expectations and create confidence in the appointment.
What should a newly appointed leader prioritise during the first 90 days?
The leader should listen, observe and test assumptions while learning how the organisation really works, both formally and informally. Clarifying the mandate, building critical relationships and securing small, meaningful wins can establish trust, create momentum and generate excitement about what may be possible
What role does the organisation play in a successful leadership transition?
The organisation shares responsibility for the transition. The Board, CEO, executive team and CHRO should clarify expectations, provide organisational context, reset working relationships and offer candid feedback. Effective transition support helps the leader contribute their perspective without simply being expected to fit into established ways of working.
How can an organisation tell whether a leadership transition is working?
Early activity is not necessarily evidence of effectiveness. More meaningful signs include clearer decisions, stronger alignment around priorities, commitments that hold beyond the meeting room and consistent delivery of agreed outcomes. These indicate that the leader and executive team are becoming effective together.
