Leadership transitions

Giving a promotion is easy. Taking one is hard.

For organisations, promotions are usually over the moment they are announced. But the person promoted now needs to act according to a new set of rules that have not been spelled out clearly. The audience has also changed the day the title did, and a full set of new expectations was raised immediately.

The first six months

The first six months after a new leader is appointed contain mostly doubt if there is no support. The person who was excellent at the last job is now being measured on completely new things, by people whose expectations they cannot yet read, in front of a team who are watching them extremely closely. Many don’t get through that period.

A significant number of new leaders fail in the first two years. And of those who succeed, almost none would call that period a good time. We are not promising a smooth transition, but what our work changes is how long the uncertainty lasts, and how much it costs the firm and the person. Within a short time the leader can usually tell what success means in the new role and who judges it, which relationships are important and which are dangerous, and how they actually want to lead. By then, that newfound leadership style starts to have a positive impact on the people they now lead.

27–46%

of executive transitions are regarded as failures or disappointments two years on. Of the transitions that fail, 68 percent do so on politics, culture and people rather than on strategy or capability.


The 27–46 percent range was compiled by McKinsey (Keller and Meaney, Successfully transitioning to new leadership roles, May 2018) from studies conducted roughly 1999 to 2013. The 68 percent figure is McKinsey’s own finding in that article.

What we do

Start here

Transition Diagnostic

How well your promotions are actually going.

We look at the leadership teams you already have, who was promoted in, how those moves have actually gone, how the teams are performing now, and where the next promotion is most likely to fail. Our diagnostics show you whether there are actually “leadership problems” in your organisation that require further action.

Executive Transition Coaching

Six months, one-to-one, with a leader stepping into a bigger role.

Six months of regular one-to-one coaching, then lighter periodic check-ins while the person settles in the new role. The work starts before day one, with a private conversation with the leader and a three-way conversation with the sponsor to agree what success looks like and when we review it together. The sponsor helps set the goals, but what the leader says in the sessions always remains confidential.

Leadership Programmes

For organisations promoting into leadership regularly.

If you move people into leadership several times a year, you already know the same difficulties come back. Instead of dealing with these issues one person at a time, these programmes put a cohort of new leaders through the journey together. For your organisation, this is more efficient, and your new leaders will stop thinking that they are the only ones finding it hard.

How we work

Every executive carries both a title and a human being. We work with you on both.

Failure under pressure is usually a problem of not seeing clearly, rather than a character or performance problem. Someone can be excellent and still be operating in the dark. We help you illuminate both pillars: what you need to strengthen yourself (Pillar I) and how to read the new environment (Pillar II).

Pillar I · The person

Confidence is built, not discovered.

Imposter experience arrives at every new level, even for the most accomplished leaders. Suddenly they feel they don’t deserve their new role or are not up to it, and there are few people they can talk about it with. We anchor executives in their human foundation: why they wanted this role, what core strengths brought them here, who they are without the title. In every leader we have worked with, there are real strengths that got them where they are. We help them become aware of them again and apply them to the specific situation they are in now. This is how healthy self-confidence is built.

Pillar II · The room

The new rules are real, but unwritten. And they can be learned.

Most organisations treat navigating a new level as a matter of character, which is both unfair and inaccurate: navigation is about information, and information can be acquired. This field has three levels, which are not symmetrical: Above the leader are the sponsors and decision-makers. A leader needs to learn what earns their support and what loses it. Beside the leader are the peers, whose cooperation is needed, but which needs to be earned. Below the leader is their team, who were equals a short while ago, and who are now watching them with a negativity bias. Some of them may think they were better qualified to get the role and may even act destructively.

Our methodology is on the one hand based on many years of concrete executive coaching experience by Luminum Partners in complex, high-stakes environments. On the other hand, we base our work on the research of some of the world’s foremost authorities on leadership and leadership transitions, with whom some of us have worked personally. On this basis, we have developed our own methodology. Among the most important influences are Michael Watkins of IMD, Herminia Ibarra of London Business School, Linda A. Hill of Harvard Business School, and Jean-François Manzoni of IMD.

The LUMINUM Transition Arc

The year after a promotion

The LUMINUM Transition Arc Role expectations increase on day one. The performance of a new leader necessarily starts below them, and then rises slowly through the early and foundation stages. Thereafter it gains momentum, before it levels off in the belonging phase. A successful leader meets the expectations in the close-out phase, and then grows beyond them. The dotted line in the diagram shows that over-confidence early on is possible, too. ROLEEXPECTATIONS ROLEPERFORMANCE THE TITLE DAY ONE Possibleover-confidence The gap between title and person

Growing into a bigger role happens in a sequence of phases. They overlap, and how long each one lasts differs from leader to leader. Each phase asks something different of the leader, and therefore we work differently in each. We accompany a person from before the role formally begins to the point where the leader has successfully arrived in it.

Phase 0: Early Stage

Before the role formally begins, the leader sits in an anticipatory state: a mix of excitement about the mandate and quiet self-questioning about whether they’re really ready for it. They may ask themselves questions such as: “why me, why now”, or also to the contrary, be in a state of over-confidence, over-estimating their leadership capabilities at this point.

Coaching outcome: A structured mandate conversation with the sponsor present, preceded by a private purpose conversation with the leader.

  • A private foundational conversation with the leader alone (why did you want this role, what strengths brought you here) prepares a solid grounding before challenges arise
  • Three-way conversation with sponsor, leader, and coach to align on what success looks like at 90 days / 6 months / 1 year
  • Surface unspoken expectations before day one

Phase 1: Foundation (1–2 months)

A leader’s thinking needs to be elevated from delivering operationally to enterprise-level strategic thinking: the leader shifts from doing a job they know to reading and shaping the organisation and people around them (e.g. sensing unspoken politics, learning what “good” means at this new altitude).

Coaching outcome: Stakeholder/ecosystem mapping exercise, paired with strengths-and-purpose coaching, so the leader isn’t only reading the room, they’re also understanding why they’re in it.

  • Leader maps the ecosystem: who matters, what “success” means in this specific micro-culture, the unwritten rules of the new table
  • Early-win candidates identified to build trust
  • Coach watches for the earliest signs of a stakeholder relationship souring

Phase 2: Identity Shifts (2–3 months)

The old self doesn’t quite fit the new chair, yet: the leader experiences several identity and behavioural shifts (e.g. no longer being the doer but being responsible for others doing).

Coaching outcome: Naming the disorientation as part of the new ecosystem, and not personal failing; the leader practises small identity-stretch experiments and grows into new ways of thinking.

  • Leader is pushed to act into the new role before feeling internally ready: the gap between title and self-experience is most acute here
  • Imposter experience and isolation at the top

Phase 3: Momentum (2–5 months)

Under real pressure for the first time, the leader’s old behaviour patterns resurface: the identity shift from Phase 2 is tested against high-stakes situations (e.g. reverting to hands-on tactical work when overwhelmed, doubting whether the new way of leading actually holds).

Coaching outcome: Catch regression in real time and use it as live material in the safe environment of the coaching sessions, reducing the tendency to regress in real business situations.

  • Regression under stress shows up most acutely here: under pressure, the leader defaults to the skills and behaviours that made them successful before
  • Simultaneously, this is where a shaky stakeholder relationship from Phase 1 can become a full trust-erosion spiral if not caught
  • Actively interrupt any forming relational problems with a specific stakeholder

Phase 4: Belonging (5–9 months)

Sustained psychological change, not a one-time event: the new way of leading becomes ordinary rather than effortful, and the isolation of the top slowly gives way to a felt sense of belonging.

Coaching outcome: Shift from active scaffolding to periodic reinforcement.

  • New habits and identity hold under normal conditions, not only under crisis
  • Setbacks are handled without full regression to old-role behaviour
  • The isolation starts to ease: the leader has built real standing now

Phase 5: Close-out and Review

A settling into who the leader has become: pride and integration replace the acute uncertainty of earlier phases, alongside a natural sense of arrival. Active coaching support recedes.

The leader has finally completely arrived in their new role.

Coaching outcome: Reflect with the leader on who they’ve become, not (just) what they delivered. Potentially a closing three-way conversation with the sponsor.

  • Sponsor-involved review: what changed, what’s next
  • Confidentiality boundary maintained throughout
