The Executive role does not begin on day one. It begins in the conversation before day one because the announcement travels faster than the entry.
I have made multiple transitions in my career. Some have been exceptional and boosted my performance and sense of belongingness. A few, have been confusing and misaligned too. Over the past several years, I have worked with CEOs and CXOs entering new organizations across industries and growth stages. I have seen a common but disturbing pattern surfacing every time. The technical preparation is thorough. The cultural and relational preparation is lacking.
This is not a minor gap. The data has been consistent for years and is becoming more urgent. Challenger, Gray and Christmas reported that 2,221 CEO departures occurred in 2024, the highest total on record since they began tracking in 2002, representing a 9% increase over an already elevated 2023. Russell Reynolds Associates found that 70% of all global indices they tracked showed higher than average CEO turnover in 2024. When you look beyond the CEO role, the numbers become harder to ignore. BoardEx data on Fortune 1000 companies shows COO turnover running at 27% and CMO turnover at 21% in recent years. Gartner’s October 2024 survey of 200 CXOs found that 56 % of C-suite leaders are likely or extremely likely to leave their current role within two years, with 27% indicating they may leave within six months. The volume of movement is no longer a cycle but has become a structural condition.
What makes this particularly consequential is that the costs compound in ways organizations consistently underestimate. McKinsey’s research on leadership transitions is direct: between 27%-46% of executive transitions are regarded as failures or disappointments within two years. About a third to half of all new CEOs are failing within 18 months of taking the role. The reasons are rarely about competence. They are almost always about culture, relationships, and political misalignment. The same McKinsey research shows that when a leader has a difficult transition, their direct reports see a 15% decrease in performance and are 20% more likely to disengage or quit. The disruption does not stay at the top. It moves through the organization.
And yet, the investment in structured integration and assimilation remains stubbornly low. Only 32% of organizations use Executive Coaching or customized assimilation plans during transitions, despite evidence that these interventions double the likelihood of success.
What makes the CEOs and CXO’s integration distinctly complex is the dual burden the role carries. The new executive is simultaneously expected to demonstrate command of their function and to read an organizational system they have not yet earned the right to interpret. They arrive with a mandate, are judged within weeks on their judgment, and are navigating a set of informal rules that no one will hand them directly. Deloitte’s analysis of the evolving C-suite found that the number of unique skills executives are expected to bring to their roles has increased substantially, with broader cross-functional accountability and elevated external pressures especially from investors, becoming the norm. The remit has expanded. The structural support has never kept pace.
Egon Zehnder’s research, developed jointly with Michael Watkins and published in Harvard Business Review, identified the most common reasons new executives fail: they do not understand the real rules of the game, and they under invest in peer relationships. Peers do not voluntarily extend support to incoming executives. That investment must be earned deliberately and early as the incumbent is still perceived to be an outsider. Any CXO who focuses primarily on their functional deliverables and assumes peer trust will develop organically is, statistically, taking a significant risk with their career.
What structured integration and assimilation requires is not a framework applied to the person. It is a quality of awareness built within the person in shortest period of time.
The Johari Window, developed by Luft and Ingham in 1955, remains one of the most precise tools for this work. It maps what a leader knows about themselves, what others see that the leader does not, what the leader conceals, and what neither side has yet discovered. MIT Sloan Management Review’s research on leadership blind spots identified four distinct types — strategic, cultural, human capital, and personal — and found that cultural blind spots are most likely to emerge when leaders apply familiar reference points to unfamiliar systems. An executive who replicates a past playbook is not being careless. They are operating from pattern recognition in an environment where the patterns are different.
Bain’s work on organizational culture offers a necessary clarification here. Culture is not a value statement. It is behaviour at scale. What the incoming executive encounters is not the culture described in onboarding materials. It is the culture experienced in who speaks first in a meeting, in what the Founder/CEO will and will not confront directly, in what gets rewarded quietly and what gets penalized without ever being named. Reading that takes time and deliberate attention. Acting before that reading is complete is one of the most common and costly mistakes a new executive makes.
In founder led organizations, the complexity is higher still. Bain’s Founder’s Mentality research makes clear that the founder’s philosophy about confrontation, pace, and people is often implicit rather than articulated. The right to challenge is earned through trust, and trust in these environments is not conferred by title. It is built through demonstrated judgment, patience, and the willingness to name what others will not.
Fast Company’s analysis of culture change leadership found a consistent pattern across organizations of different sizes and sectors: executives who role model the behaviours they wish to see move culture faster than those who announce it. An incoming CEO or CXO cannot describe the culture they intend to build from a distance. They must inhabit the existing one first, understand it second, and reshape it from within by modeling behaviours.
The first 90-180 days, properly designed, are not about proving impact. They are about building the quality of understanding that makes impact sustainable. The organizations that invest in structured integration for their incoming executives reduce time to full impact by up to 40 %, according to Egon Zehnder’s research. Given that a failed executive transition costs between three and four times the position’s annual salary, according to SHRM, that is not a coaching return. It is a business case.
Leadership transitions are not administrative events. They are psychological and political journeys. When we design them deliberately, time to full impact compresses dramatically. When we don’t, we gamble with culture, performance, and credibility. And at the very top, the stakes are never small.
The question worth discussing, whether you are a CEO or CXO joining a new organization, or a Board welcoming one, is this: Are you treating integration as orientation, or as the most consequential leadership investment you will make in the first year?
A thought through investment and “we will figure it out” are not the same thing.
I have developed a structured CEO and CXO Assimilation Coaching Plan that draws heavily from global research. The intent is not to give the incoming executive answers. It is to build the quality of awareness — of self, of context, of relationship and the external environment — that allows them to find quality answers faster. If you are keen, I would love to connect.

When a new CEO or CXO walks into the organization, the announcement has already travelled faster than they have. I have made multiple transitions in my career. Some have been exceptional and boosted my performance and sense of belongingness. A few, have been confusing and misaligned too. Backed by global research and my personal experiences, I have explained why a thought through investment in executive integration gives disproportionate returns vs the “we will figure it out” onboarding approach.
