Issue 4: External Hire or Internal Promotion?

⏱ 5-minute read

When a senior role becomes vacant, should you back the talent you already have — or bring in someone new?

The Boardroom Question

When a senior position becomes available, where should you look first — inside your organisation or outside it?

Promoting from within can provide continuity, retain valuable knowledge and demonstrate that talented people have genuine opportunities to progress.

An external appointment, however, can bring fresh thinking, different experience and capabilities that may not currently exist within the business.

Neither approach is automatically right.

The real question is: what does the organisation need next?

Don’t Start with the Person

One of the easiest mistakes to make when replacing a senior leader is to begin with potential candidates.

“Could Sarah step up?”

“What about James?”

“Who could we attract externally?”

A better starting point is the role itself.

Before discussing names, boards should consider what the organisation will require from this position over the next three to five years.

Has the business strategy changed?

Is the organisation entering new markets?

Is transformation required?

Are new commercial, digital or regulatory capabilities becoming more important?

The person who successfully performed the role for the past five years may not necessarily represent the profile required for the next five.

Define the future role first. Then decide who is best equipped to deliver it.

The Case for Internal Promotion

Promoting an existing employee can bring considerable advantages.

Internal candidates already understand the organisation, its culture, its customers and many of its key relationships.

They may also have established credibility with colleagues and a detailed understanding of how decisions are really made.

An internal appointment can mean:

• Faster integration into the role.
• Valuable organisational knowledge is retained.
• Greater continuity for employees and stakeholders.
• Lower initial hiring risk.
• A powerful signal that career progression is genuinely possible.
• Improved retention among ambitious employees.

There is also something important psychologically about seeing colleagues progress.

When people believe there are opportunities to build their careers within an organisation, they have another reason to stay.

The CIPD highlights the value of nurturing internal talent, particularly where organisation-specific knowledge is important, while also recognising that external appointments can bring valuable new ideas and approaches.

But Familiarity Can Create Blind Spots

Internal promotion isn’t without risk.

The strongest functional performer isn’t automatically the strongest future executive.

A highly successful Finance Director may not necessarily be the right future CEO.

A brilliant editor may not naturally become an outstanding Publisher.

A technically exceptional Financial Services leader may need broader commercial or people-management experience before moving into an enterprise-wide role.

Internal candidates may also be closely associated with existing ways of working.

If the organisation needs significant transformation, a different perspective may be valuable.

The question therefore shouldn’t be:

“Who deserves the promotion?”

It should be:

“Who is best equipped to lead the organisation through its next chapter?”

The Case for Looking Outside

External appointments offer something internal candidates cannot always provide: experience gained elsewhere.

A new leader may have already tackled challenges your organisation is encountering for the first time.

They may bring:

• Experience of different markets or business models.
• New commercial thinking.
• Different networks and relationships.
• Transformation experience.
• Specialist capabilities.
• A fresh perspective on long-standing challenges.
• Greater willingness to question established assumptions.

This can be particularly valuable when an organisation is changing direction.

If the strategy is changing significantly, it is reasonable to ask whether the capabilities required to deliver that strategy already exist internally.

Sometimes they do.

Sometimes they don’t.

External Doesn’t Automatically Mean Better

There is a danger, however, in assuming that an impressive external CV automatically represents an upgrade.

Someone who has succeeded brilliantly in one organisation may struggle in another.

Culture matters.

Leadership style matters.

The circumstances in which previous success was achieved matter.

External candidates also need time to understand the organisation, build relationships and establish credibility.

That’s why executive appointments should never simply be about finding the person with the biggest job title or most recognisable employer on their CV.

The right appointment is about fit, capability and future potential.

Publishing: Balancing Heritage with New Thinking

This decision can be particularly nuanced within Publishing.

Many organisations have deep institutional knowledge and long-standing relationships with authors, agents, retailers and other partners.

An internal candidate may understand those relationships exceptionally well and offer valuable continuity.

At the same time, publishing continues to evolve.

Changing consumer behaviour, digital developments, international opportunities, new business models and emerging technology can create a need for experience that may not currently exist within the organisation.

The strongest appointment may therefore depend on what the business is trying to achieve next.

Continuity may be exactly what is required.

Or the next phase may call for a different perspective.

Financial Services: Experience Versus Transformation

Financial Services organisations face a similar balancing act.

Internal candidates can bring deep understanding of the organisation’s regulatory environment, risk appetite, customers and operations.

That knowledge can be extremely valuable in senior appointments.

But businesses undergoing transformation may also benefit from leaders who have successfully navigated comparable change elsewhere.

New regulation, technology, operational resilience, changing customer expectations and evolving business models can all alter the capabilities required around the boardroom table.

Again, the question isn’t simply whether an internal or external appointment is preferable.

It’s whether the individual has the capabilities required for where the organisation is going.

There’s a Third Option: Test the Market

Perhaps the most useful approach is not to decide too early.

An organisation can have a strong internal candidate and still explore the external market.

That doesn’t undermine the internal person.

Done properly, it provides a benchmark.

A robust process allows the boardroom to understand:

• What comparable talent exists externally.
• How the internal candidate compares.
• Whether additional capabilities are available in the market.
• What compensation expectations look like.
• How attractive the opportunity is to external executives.

The outcome may reinforce the case for internal promotion.

Or it may reveal possibilities the organisation hadn’t previously considered.

Either way, the decision becomes better informed.

Benchmark Before You Decide

This is where market mapping can be particularly valuable.

Organisations don’t necessarily need an active vacancy to understand the external talent landscape.

Mapping relevant executives ahead of time allows boards to see where talent sits, what experience is available and how their own succession candidates compare.

It replaces assumption with evidence.

And when a senior vacancy eventually arises, the organisation is already starting from a position of knowledge.

Five Questions to Ask Before Making the Decision

Before choosing between an internal promotion and an external appointment, ask:

1. What will this role need to deliver over the next three to five years?
2. Do we genuinely have those capabilities internally?
3. Is our internal candidate ready now — or simply high potential?
4. Would an external perspective add something the organisation currently lacks?
5. Have we benchmarked our internal options against the external market?

Only then should the conversation turn to names.

Key Takeaways

• Start with the future requirements of the role, not the available candidates.
• Internal promotion can provide continuity, knowledge and a powerful retention message.
• High performance in a current role doesn’t automatically mean readiness for the next one.
• External hires can introduce capabilities, experience and perspectives that don’t exist internally.
• External candidates still need to demonstrate cultural and organisational fit.
• Benchmarking internal candidates against the market can lead to better-informed decisions.
• The right answer isn’t always “internal” or “external” — it’s the person best equipped for what the business needs next.

The Boardroom Question

If a key member of your executive team left tomorrow, would you automatically promote from within, automatically look outside — or have enough information to make an objective decision?

At Mosaic Executive Search, we help organisations across Publishing and Financial Services understand the external talent market and make informed senior appointment decisions.

Whether the eventual answer is an external appointment or an internal promotion, executive search and market mapping can provide valuable insight into the talent available and help boards benchmark their options before making a critical decision.
