Key Highlights
- Internal candidates bring valuable knowledge of the company’s culture, operations, and strategy, allowing them to transition into leadership more quickly.
- External candidates can be a better choice when business performance is weak, market conditions are changing, or internal leaders lack the skills needed for the next stage of growth.
- Neither internal promotion nor external recruitment guarantees better results. The company’s circumstances and the incoming leader’s approach are important factors.
- Boards should develop multiple potential successors and maintain an emergency plan to prepare for unexpected leadership departures.
- Comparing internal and external candidates against the same leadership criteria helps boards make fair, objective, and strategic hiring decisions.
- A planned handover, where an incoming leader works with the current CEO, helps support a smoother transition and improve succession outcomes.
- Boards should review their leadership plans at least annually, aligning successor requirements with business goals and ensuring continuity for both planned and unexpected departures.
Few choices shape a company like the pick of its next CEO. A strong leader lifts the whole business. A weak pick can hold it back for years. So, boards face big questions. Do you grow a leader from within, or do you look outside?
Both paths can work. Here is what the data says, where each path shines, and how to build a plan that uses both.
Why CEO Turnover Keeps Rising
The pressure on boards is real, and the numbers show it. The Conference Board says CEO turnover sped up at large companies in 2025. The boards also looked outside more often. Through September 2025, 33% of new S&P 500 CEOs were outsiders. A year earlier, that figure was 18%.
Patience for weak results is thin, too. In the 2024 data, 42% of S&P 500 successions happened at lower-performing companies. In 2017, it was 29%. Executive hiring at the top now happens under a bright light.
The Case for Succession Planning
Growing a leader from within has clear perks. Insiders know the people, the products, and the culture. They need less time to find their feet. The same Harvard Law School Forum post says the COO is still the most common path to the top job. CFOs made up 15% of new insider CEOs in the S&P 500 in 2024.
Harvard Business School professor Joseph Bower has studied this for years. In his look at 1,800 successions, results were better when insiders took over. He adds that outsiders cost more, and that an early jump in stock price says little about later results. His view is blunt: “The board should be developing insiders.” Still, later HBR research found the two groups did about the same.
When an External Search Makes Sense
Sometimes, the best leader is not on the payroll.
Researchers at MIT Sloan Management Review found that, on average, outsiders do no better or worse than insiders over three years. Context drives the gap. Outsiders beat insiders at firms with a recent record of poor results. They also did better when they held off on big strategy shifts early on.
Timing matters, too. A classic study of Fortune 200 firms by Harvard Business School professors Rakesh Khurana and Nitin Nohria found no real change when an insider replaced a retiring CEO. But when an outsider replaced a fired CEO, performance rose by more than 4% over the next three years.
Outsiders do carry more risks. A 2019 study in the Strategic Management Journal found that their results swing wider, for better or worse.
A well-run executive search casts a wide net. It can find skills the company lacks, such as turnaround or digital know-how. Use this quick guide:
- Lean inside when strategy is sound, culture is strong, and a successor is ready.
- Lean outside when results lag, the market is shifting, or no one inside is ready.
Why Many Boards Aren’t Ready
Most boards say succession matters. Fewer have the bench to back it up.
An older but telling Stanford Rock Center study found a gap. Half of the boards believed they had an effective plan. Yet only 25% said they had enough ready successors. Directors also said they would need nearly 90 days (about 3 months) to replace a CEO who left today. C-suite hiring gets hard when the bench is thin.
Why wait? A PwC survey found that close to one-third of board directors viewed satisfactory CEO performance as a reason to postpone succession planning, even when preparing for future leadership changes remained important. A calm moment feels like the wrong time to plan. The 2024 NACD survey tells a similar story. Public companies still need stronger long-term plans for planned and sudden exits.
How to Run Both Tracks
The best boards don’t pick a side early. They build both paths and compare them.
- Define the job. Write down what the next CEO must deliver over the next three to five years.
- Build the inside bench. Name two or three candidates and give them stretch roles.
- Test the market. Quietly size up outside talent. A trusted executive recruitment partner can do this without tipping off the press or staff.
- Write the emergency plan. Name who steps in if the CEO leaves tomorrow.
- Score everyone the same way. Judge insiders and outsiders against one list of needs.
Some boards add a middle path. In a “relay” handoff, the board names the heir early, and the two leaders work side by side for a time. Research from the Indian School of Business found that relay successions beat both plain insider and outsider picks. The edge was biggest at firms with weak results before the handoff.
Then review the plan each year. Harvard’s governance forum advises that the full board should look at the plan at least once a year. That keeps the needs current. Planning is not a vote of no confidence in the sitting CEO. It is plain risk control.
What Philippine Boards Should Know
Local rules point the same way. The SEC’s code for listed companies says the board should adopt an effective succession planning program for directors, key officers, and management. The code covers more than the CEO job. It asks boards to plan for key officers, too.
One Inquirer opinion piece notes that most listed Philippine firms have a family group as majority owner. That makes a clear, fair process even more vital. It keeps family members, insiders, and outside candidates on equal footing.
The Bottom Line
Succession planning and external search are not rivals. They work best together. Plan early. Build your bench. Watch the market. Then pick the path that fits your company’s moment, not your habits.
Key takeaways:
- Insiders suit steady firms. Outsiders suit firms that need a reset.
- Most boards need a deeper bench and a written emergency plan.
- Score insiders and outsiders on the same list and review the plan yearly.

FAQs
Do insiders or outsiders make better CEOs?
Neither wins every time. Context matters most. Outsiders tend to do better at firms with a record of poor results, while insiders bring culture and speed.
How often should a board review its CEO succession plan?
At least once a year. Review it again after any big change in strategy or leadership.
What is an emergency succession plan?
It names who steps in if the CEO leaves without warning. It also lists the steps the board will take and who owns each one.
When should a board hire an outside CEO?
Consider it when results lag, strategy must change, or no insider is ready.
