CEO succession: Avoiding the unanticipated Domino Effect

A large financial services company promoted a key leader into the position of CEO. Two of their peers were also vying for the top job. Almost immediately, the other two executives left the company. This created an unexpected leadership vacuum that cascaded within their respective departments, where no one on either team was able to step up into the suddenly vacant leadership spots. The lack of “ready now” successors required the company to look outside to replace those executive leadership roles, significantly disrupting their critical strategic transformation effort and creating additional chaos at the top of the company at a time when they could ill afford to slow momentum.
Similarly, a global manufacturing company promoted a key leader into the CEO role who lacked sales and marketing experience – an area where his predecessor had deep expertise. This expertise was a critical driver in the company’s success to date, and the gap at the top was stalling revenue growth and impeding the new CEO’s ability to deliver on the Board’s expectations. In order to fill the CEO’s knowledge gap, the company reorganized the head of sales and marketing role so that it was led by two executives instead of one. This unanticipated restructuring created confusion across the C-Suite and the rest of the sales and marketing organization regarding roles and responsibilities, which compounded their challenges in driving growth. The unexpected increased salary costs accompanying the additional executive role further impacted the bottom line, as well.
What these two examples illustrate is the Domino Effect. The Domino Effect occurs when a star performer is promoted, and there is no “ready now” successor to fill the role they are vacating. With so much attention placed on getting a new CEO into the role, the Domino Effect can cascade down through the organization and is an often hidden and unanticipated outcome that can hinder even the most capable chief executive from successfully taking the reins.
Assessing the impact of the Domino Effect
Conventional wisdom and the literature suggest that CEOs sourced internally outperform CEOs that are sourced externally. For example, in Harvard Business Review’s “Best CEOs of the World” top 100 list, 84% came from internal promotions1. The majority of leaders who ascend to the CEO role are COOs, CFOs, divisional CEOs, and some are “leapfrog” leaders identified below the C-Suite2. A question that has not been addressed is: what happens to the performance of the company when there are no internal candidates for the new CEO’s previous role? In other words, what is the impact of the Domino Effect on company performance?
To answer this question, we compared the S&P 500 twenty best performing companies3 with the twenty worst performing companies4 based upon percentage change in stock price.
What happened at the Best Performing companies?
Within the top 20 best performing companies, 75% of the CEOs were internal with 5 of the CEOs being founders of the company and 10 being promoted into the role. For their former positions, from which they were promoted, four were filled by internal candidates, and two were replaced with external candidates. Examining the leadership teams on the company’s websites, it appears that in three incidences, the role that the CEO vacated no longer exists. In one case the role was restructured and split into two different positions.
What happened at the Worst Performing companies?
70% of the CEOs at the worst performing companies came through promotions or being founder led (12 and 2 respectively), which is nearly identical to the best performing companies. All things being equal, one would expect a similar trend regarding the number of internal vs. external replacements for the CEOs’ previous roles from which they were promoted. However, we found that there were differences. Only three of the backfilled positions were placed by internal candidates and four were placed by external hires. In three of the companies, the position no longer exists, and two of the companies restructured the position.
Understanding the impact: disruption and worsening performance
The research shows little difference between the best and worst performing companies in relation to internal promotions and external hires for the CEO position. However, we do see more organizational disruptions in the replacement of the previous roles held by the CEO. A disruption is defined here as either the company was required to hire from the outside, restructure the role, or eliminate the role altogether. All of these create added turmoil and challenge for the new CEO as they try to move quickly to onboard and start delivering impact.
We found that disruptions were present in 60% of the top-performing companies, compared to 75% of the poorest performing companies. While more research is needed to uncover the nuances, our research suggests that companies with a stronger bench for newly promoted CEOs’ previous positions have less organizational disruption and outperform those who do not have a strong bench.
Tackling the Domino Effect before it falls
While CEO succession garners the greatest amount of the spotlight in the press, among board members, and in public sentiment of the health of a company, our research underscores the need for CEOs, CHROs, and Boards to focus on the Domino Effect as part of their C-Suite succession process. That is, creating a bench of potential successors targeted specifically for the CEO’s previous role, and the roles deeper within the organization that could replace those who are being elevated in the company at the time of the new CEO transition.
Consider these best practices to get ahead of the Domino Effect:
- Build the backfill into the identification process. When identifying potential candidates for the CEO, simultaneously consider who may replace that candidate for their current role.
- Focus on the role rather than the person. You may not be able to replace the next CEO’s position with one individual, but you may be able to replicate their skills with people who can excel in the role with complimentary skills.
- Expand the purview of success profiles. Create success profiles for the CEO and those roles that are likely feeder pools for CEO. Ensure that the success profiles are future focused rather than focused on what is important today. Business realities change over time. What makes someone successful today may be different than what is required in the next 3 to 5 years.
- Leverage the power of data for determining future success. As you look at your bench, use structured assessment processes to assess individuals against the success profile, reduce the risk of biases towards individuals, and determine their readiness to address the future business challenges that the organization will face.
- Comprehensively build the right bench. Look broad and deep within the organization when identifying potential successors. You may find those “leapfrog” leaders who would otherwise be overlooked.
- Continually refresh your succession slate. Given the cascading impacts of the Domino Effect, it is more important than ever to ensure your slate is up to date with viable candidates for higher level positions. Consider doing so on at least an annual basis.
- Ensure that succession is seen as a strategic imperative across the leadership of the organization rather than a single event of placing a new CEO. The CEO and the CHRO should own the succession process, the Board should be involved, and the focus should stay equally on the CEO role and the successor leadership roles throughout the organization.
Finding, placing, and ramping up a new CEO is a momentous decision with big outcomes at play – for the CEO’s own success and the viability of the organization. If you embrace the opportunity to turn the Domino Effect into a strategic gameplan, you will be positioned both for accelerated success and impact.

Sparking Change: How BTS Spark and Tostan are building grassroots leadership for sustainable impact
In a world where transformation often feels complex and distant, real progress is often sparked at the community level, through leaders who create change from within.
In Senegal, a partnership between BTS Spark and Tostan, a nonprofit dedicated to community-led development across Africa, is bringing this idea to life. It’s a reminder that sustainable leadership isn’t built by imposing new systems. It grows when people are equipped to lead themselves.
A ground-up approach to lasting change
Since 1991, Tostan—whose name means "breakthrough" in Wolof—has partnered with rural African communities to advance human rights, health, literacy, and economic development. Its Community Empowerment Program (CEP) weaves together practical knowledge and human rights education, enabling communities to define and pursue their own visions of progress.
Across eight countries and more than five million lives, Tostan’s approach has led to deep-rooted changes, including the voluntary abandonment of harmful traditional practices. Not by directive, but by choice.
It’s an approach that shows leadership capacity isn’t something to be delivered from outside. It’s something to be nurtured from within.
Meeting communities where they are
In 2024, BTS Spark deepened its collaboration with Tostan through an in-person leadership workshop, led by a BTS Spark consultant, following a year of virtual engagement.
The visit coincided with a leadership transition at the executive level—a pivotal moment requiring clarity, continuity, and resilience. Through targeted coaching and workshops, BTS Spark worked alongside Tostan’s leaders to support the transition and strengthen leadership capacity at every level of the organization.

The focus wasn’t on delivering a model. It was on listening, amplifying existing strengths, and equipping leaders to navigate complexity with confidence.
Practical tools for complex challenges
As part of the ongoing collaboration, BTS Spark also provided custom-designed micro-simulations focused on sectors vital to community sustainability: climate resilience, microfinance, and agriculture.
These micro-sims offer leaders a chance to engage with real-world decision-making challenges in a safe, practical environment—an approach that mirrors how leadership development increasingly happens: not through theory alone, but through repeated, real-world application.


It’s a reminder that growth is rarely linear. It’s built through practice, reflection, and adaptation over time.
Building leadership that endures
The work between BTS Spark and Tostan reflects a broader truth:
Leadership isn’t confined to titles, industries, or regions. It emerges where people are given the tools, trust, and space to act.
Sustainable change, whether in communities or organizations, happens when leadership capacity is strengthened closest to where challenges are lived every day.
The partnership also highlights the power of investing in local capability: focusing on what’s already working, building resilience from within, and preparing leaders not just to meet today’s challenges, but to shape tomorrow’s opportunities.
Moving forward: Scaling with purpose
The work in Senegal is continuing to evolve. BTS Spark and Tostan are exploring ways to extend leadership development to more communities, deepen their impact, and continue supporting transformation through shared expertise and partnership.
It’s a model rooted in respect, collaboration, and the belief that leadership is most powerful when it reflects the realities and aspirations of the people closest to the work.

Navigating the new dawn of talent strategy: 5 shifts reshaping work
The accelerating pace of change in the modern workplace has necessitated a proactive approach to envisioning the future and what will be required to support organizations as they evolve and adapt.
To advance the conversation, we recently facilitated a future-storming session to reimagine the future of work and talent strategy.
Future-storming is the process of identifying risks and trends that might affect your business or industry vertical, combining them in new ways, and thinking of solutions to mitigate these risks. The ambition? To break the chains of traditional thought, sparking insights into the evolving domain of talent strategy.
Here are five transformative themes that surfaced during the session:
1. Fluidity of talent:
Gone are the days when “talent” described a fixed set of competencies an individual brought to the table. In today’s world, talent is an amalgamation of adaptability, resilience, and the capability to evolve. AI and automation, while replacing routine tasks, can't replace the human capacity to grow, reimagine, and pivot.
The traditional talent pool, defined by rigid skill sets, is making way for a reservoir of potential. It's about harnessing the innate human ability to unlearn, relearn, and traverse uncharted territories. Recognizing this fluid nature of talent can redefine how organizations recruit, retain, and nurture their human capital. The future will prize the ability to learn and relearn, shifting from fixed competencies to a reservoir of ever-evolving potential.
2. Skill evolution, continuous, embedded learning:
The gig economy drives continuous learning, demanding flexibility and growth. The concept of learning in organizations is evolving beyond formal training modules. Today's employees are in a perpetual state of growth, thanks to digital platforms, cross-cultural collaborations, and the changing demands of their roles.
No longer can learning be a one-off event. It must be seen as a journey where every experience, every interaction, and even every failure is an opportunity to grow. This shift to continuous learning also means embracing failures as valuable lessons, promoting a culture of curiosity, and embedding learning in everyday tasks. Organizations that foster curiosity and value each failure as a learning opportunity will lead the way. The pathway to career progression is increasingly carved by demonstrable capabilities.
3. Culture, diversity, and the rich tapestry of learning:
Cultural diversity isn't just a buzzword; it's an untapped treasure for organizational growth. There is a burgeoning global talent landscape with increased cultural exposure which fosters innovation and holistic problem solving. Diverse teams, with their unique experiences and backgrounds, bring varied problem-solving methodologies, fresh perspectives, and richer insights, serving as an invaluable asset for organizational growth.
These multi-cultural interactions and experiences act as opportunities for informal learning, introducing employees to different ways of thinking and innovative solutions. Encouraging such interactions not only fosters a sense of inclusivity but also ensures a holistic organizational growth trajectory.
4. Embracing the tech-human synergy:
The technological renaissance envisages a world where computers and robots assume many of our current roles, from documentation to Q&A. The emerging synthesis of technology and biology, including embedded tech and wearables, offers insights, from employee well-being to real-time emotional feedback.
While technological advancements promise efficiency and scalability, the human element's value remains unmatched. The blend of technology with human intuition, creativity, and empathy is the key to future success. The ideal modern professional is one who not only leverages technology but also understands its boundaries, ensuring that technology serves humanity and not the other way around. While technology offers efficiency, the human touch provides empathy, intuition, and creativity.
With advancements come ethical considerations, especially with AI and machine learning. Balancing technological ability with an ethical foundation ensures that organizations remain not just profitable, but also principled.
5. The subtle art of leadership:
Work will undergo an existential reevaluation. The rise of decentralized leadership, the emphasis on enriching organizational culture, and a holistic approach to talent assessment will redefine organizations. With flattened organizational structures, fostering trust and embracing entrepreneurialism are necessities. Leaders will be more focused on collaboration, understanding, and guidance. In this landscape, leadership also means being tech-savvy, yet understanding the nuances of human emotion is also requisite. It's about removing barriers, and being a facilitator and mentor.
Furthermore, as work boundaries blur, leaders need to be agile, adaptive, and always ready to guide their teams through tumultuous waters. The responsibility is to create environments where employees feel empowered, engaged, and eager to contribute.
Reflections
The future-storming session offered a blueprint for navigating the complex terrains of the talent landscape of tomorrow. The future of talent and learning is unfolding, and through sessions like these, we aim to empower leaders to be the sculptors of that future.

3 signs you’re in a leadership rut
Are you in a leadership rut?
It’s a hard question to answer because of the nature of ruts. You often don’t realize you are in one until you’re out of it. This is particularly true for senior leaders, who have demanding schedules and packed calendars, which may further delay the realization of being in a rut: You’re just too busy to notice.
Why is this a problem? For leaders, the risks of being in a rut extend beyond being caught in a boring routine or stuck in an emotional funk. Left unchecked, company innovation and performance suffers, engagement and morale may drop, and good talent leaves when leaders and teams fall into ruts. Leadership ruts are serious business, but what makes them hard to see is that the signs often appear in small ways. How do you know if a rut is sneaking up on you? Here are a few indications.
- No bright spots on the calendar. Recently, I asked a client, “What are you looking forward to on your calendar?” There was a long pause. He replied, “Not much.” If this feels like you, it’s an important area to explore, because calendars aren’t just timetables, they mirror how we spend our days. So, take a few minutes to review your calendar on a regular basis. Too many days in a row without bright spots has an impact. Over time, it can hurt our motivation, engagement, creativity, and we may not even realize it is happening to us. Think about it this way. Are you really at your best at meetings you don’t look forward to? Eventually, too many of those impact a leader’s performance in all kinds of ways.
How to address: Recognize that a great calendar won’t just happen by itself. It’s easy to get caught into a trap of thinking that we don’t have control over our calendars or buy into the old story that work shouldn’t be about fun. As good as you are, you’ll be even better if you have days to look forward to and a calendar that energizes you, so commit to making small improvements in your calendar (more bright spots and fewer meetings you dread) and you’ll yield instant results.
- Too much of the same. Being in the same role for a while isn’t necessarily a sign you’re in a leadership rut, so the caveat here is that “it depends.” If you’re in the type of company where most people advance or move into different roles every 18-24 months and you haven’t, it’s an area to explore. While you’re at it, consider other aspects of your work that haven’t changed in a while, whether it’s the people on your team, the work you’re engaged in, or the number of new situations or people you’ve encountered. This can lead to a blind spot buildup and dull our ability to stay fresh, embrace change, or expose ourselves to diverse people and experiences that enable us to think differently.
How to address: Deliberately force yourself to mix it up, and this is particularly true if you’ve worked at the same company for most of your career. Raise your hand to do something new on a regular basis that is a stretch for you. Over the years, I’ve had clients do everything from speaking at a major client event, to living overseas, to attending a Tony Robbins seminar and walking over hot coals. This is also a time when leaders engage a coach or join groups of other like-minded leaders to get exposed to new ideas. Whatever you choose, put it on your calendar so you know it will happen. A few small tweaks can create major change and transformation.
- You’ve stopped dreaming big for yourself. Being in a leadership rut can often start from a place of good intentions. Perhaps you’ve been leading through a challenging time and you’ve been focused on getting through the issues at hand. The question to ask yourself is when are you not in a period like this? If it’s always code red, all the time, it’s easy to stay in a permanent state of firefighting. This produces the worst kind of leadership rut, where we are never able to get beyond the urgent and tackle the important, and it can lead us to some dark nights of the soul, where we wake up, 10, 20 years later and regret not tending to our longer-term goals, hopes, and visions for our own lives.
How to address: Make daydreaming as important and strategic an activity as any other high priority in your life and treat it seriously. Set aside time to sit in your favorite chair in a quiet corner of the house with your pen and notebook and answer some simple questions for yourself, like, “What do I dream about?” or “What do I want to do that I haven’t done yet?” Daydreaming is about unfiltered, unedited thinking, and it is where some of the best ideas for your life and work can happen. The first few times you do this, you may feel uninspired or cringe at the word ‘daydreaming.’ Forget about all of that and remind yourself it is what the most enlightened, productive leaders do to get even better.
- Falling into a rut can start off innocently, like always going to the same restaurant and ordering the same thing off the menu. In leadership, it’s risky, because it limits our ability to be everything we can be for our organizations, our teams, and ourselves. Toughest of all is the fact that other people may recognize we’re in a rut long before we do. The good news is that we can address this with a few simple changes, and when we do, leadership becomes vibrant, energizing, and returns to technicolor again.

From top-down to judgment all around: The AI imperative for organizations
Each business revolution has reshaped not only how businesses operate, but how they organize themselves and empower their people. From the industrial age to the information era, and now into the age of artificial intelligence, technology has always brought with it a reconfiguration of authority, capability, and judgment.
In the 19th century, industrialization centralized work and knowledge. The factory system required hierarchical structures where strategy, information, and decision-making were concentrated at the top. Managers at the apex made tradeoffs for the greater good of the enterprise because they were the only ones with access to the full picture.
Then came the information economy. With it came the distribution of information and a need for more agile, team-based structures. Cross-functional collaboration and customer proximity became competitive necessities. Organizations flattened, experimented with matrix models, and pushed decision-making closer to where problems were being solved. What had once been the purview of a select few, judgment, strategic tradeoffs, and insight became expected competencies for managers and team leads across the enterprise.
Now, AI is changing the game again. But this time, it’s not just about access to data. It’s about access to intelligence.
Generative AI democratizes access not only to information, but to intelligent output. That shifts the burden for humans from producing insights to evaluating them. Judgment, which was long the domain of a few executives, must now become a baseline competency for the many across the organization.
But here’s the paradox: while AI extends our capacity for intelligence, discernment, the human ability to weigh context, values, and consequence, is still best left in the hands of human leaders. As organizations begin to automate early-career work, they may inadvertently erase the very pathways and opportunities by which judgment was built.
Why judgment matters more than ever
Deloitte’s 2023 Human Capital Trends survey found that 85% of leaders believe independent decision-making is more important than ever, but only 26% say they’re ready to support it. That shortfall threatens to neutralize the very productivity gains AI promises.
If employees can’t question, challenge, or contextualize AI’s output, then intelligent tools become dangerous shortcuts. The organization stalls, not from a lack of answers, but from a lack of sense-making.
What organizations must do
To stay competitive, organizations must shift from simply adopting AI to designing AI-aware ways of working:
- Build new learning paths for judgment development. As AI replaces easily systematized tasks, companies must replace lost learning experiences with mentorship, simulations, and intentional development planning.
- Design workflows that require human input. Treat AI as a co-pilot, not an autopilot. Embed review checkpoints and tradeoff discussions. Just as innovation processes have stage gates, so should AI analyses.
- Make judgment measurable. Assess and develop decision-making under ambiguity from entry-level roles onward. Research shows the best learning strategy for this is high-fidelity simulations.
- Start earlier. Leadership development must begin far earlier in career paths, because judgment, not just knowledge, is the new differentiator.
What’s emerging is not just a flatter hierarchy, but a more distributed sense of judgment responsibility. To thrive, organizations must prepare their people not to outthink AI, but to out-judge it.

High-performing teaming
Work today is too complex for individuals to succeed in isolation. Almost every critical decision, innovation, or transformation depends on teams working effectively together. Leaders rely on their teams to deliver results. Teams, in turn, rely on their leaders to create the conditions where performance is possible. This exchange, what leaders need from their teams, and what teams need from their leaders, sits at the heart of what we call teaming.
When teaming is strong, leaders get what they need from their teams [creativity, resilience, execution] and teams get what they need from leaders [direction, support, and the conditions to thrive]. It’s how strategy becomes action, how uncertainty becomes opportunity, and how businesses stay competitive in a fast-changing world.
