Why so many succession decisions fail, and what smart leaders do differently.

Succession planning sounds simple.

Identify the next leader, develop them, and hand over the reins when the time comes.

In reality, it’s one of the hardest decisions a senior leader (who cares about the future success of the organisation) has to make.

When you’re choosing someone to step into your role, you’re not just selecting the most capable person.

You’re choosing the person who will continue to positively shape the culture, performance and direction of the organisation long after you’ve moved on.

And that’s where many succession decisions go wrong.

Not because leaders don’t care, but because the way we traditionally identify future leaders is flawed.

The problem with instinct

Most succession decisions are made using a combination of:

• past performance

• visibility with senior leaders

• technical expertise

• gut instinct

Those things matter.

But they don’t help you see things 100% fairly across all potential candidates, or necessarily tell you how someone will perform when the leadership stakes get higher.

We all have biased views to contend with. And the skills that make someone successful at one level are rarely the same skills required at the next.

Especially when the next step involves leading leaders rather than leading a specific team or tasks.

I’m seeing this play out right now with several leaders I’m coaching who are preparing to step away from their roles in the next 12–24 months.

Each of them faces the same challenge:

Who is genuinely ready to step into the role… and how do you know?

That’s a far more complex question than most succession processes acknowledge.

Leadership is rarely about what people think it is

When people think about leadership readiness, they often focus on the visible things:

• strategy

  
  

• finance

  
  

• technical capability

  
  

• experience (time in role)

Those things matter, but they rarely determine whether someone will succeed as a senior leader.

In my experience working with leaders and leadership teams, the behaviours that really determine leadership success tend to sit somewhere else.

Things like:

• emotional intelligence

  
  

• executive presence

  
  

• the ability to inspire and influence across all functions

  
  

• how someone handles challenge, pressure and disagreement

  
  

• how they are experienced by the people around them

  
  

• how they lead through change and uncertainty

These behaviours shape whether someone can build trust, align teams and make sound decisions under pressure.

In other words, whether they can lead brightly, with clarity, confidence and impact.

The challenge is that these behaviours are often the hardest to assess fairly.

Especially for the leaders themselves.

The blind spot most leaders never see

Every leader has blind spots.

It’s part of being human.

But the more senior someone becomes, the fewer people are willing to point out those blind spots.

Which means the leaders most likely to progress are sometimes the ones least aware of how their behaviour lands with others.

They may be brilliant technically.

They may ooze charisma.

They may deliver strong results.

But if their leadership style damages collaboration, erodes trust, or shuts down healthy challenge, that becomes a serious problem at senior levels.

In fact, all leaders I work with discover that the biggest leadership gaps are not technical; they’re behavioural.

And behavioural blind spots are exactly the ones most people struggle to see without honest feedback.

The cost of getting it wrong

When the wrong leader is promoted, the impact is rarely small.

Teams disengage.

Collaboration breaks down.

High performers leave.

Strategy slows down.

And organisations often find themselves needing to replace the leader again within a few years.

All of which is hugely expensive — financially, culturally and reputationally.

Which is why the best leaders take succession planning seriously.

Not just as a process, but as a responsibility.

What smart leaders do differently

The most effective leaders don’t rely on instinct alone.

They combine judgement with insight.

They want to understand👇🏽

• How potential successors are experienced by others

• Where their leadership strengths already show up

• Where their blind spots may sit

• Whether they are willing to grow

The only way to do this is through robust, structured assessments that focus on the emotionally intelligent behaviours that every leader needs to demonstrate in a senior leadership role.

Because leadership readiness isn’t just about capability.

It’s about behaviour.

And it’s about mindset.

A leader who isn’t willing to grow, learn and improve will never be as effective as the one who is.

The leadership test most people miss

One of the clearest indicators of leadership potential is surprisingly simple.

How someone responds to honest behaviour-based feedback.

The leaders who lean into feedback, reflect on it and act on it tend to grow quickly.

The leaders who avoid it, defend against it or dismiss it often struggle when the leadership demands increase.

Which is why the most effective succession processes don’t just assess current capability.

They also reveal who is willing to develop.

And that tells you a great deal about who will thrive in the future.

Succession planning is a leadership legacy

Choosing the next leader is one of the most important decisions any senior leader will make.

Not because it defines their tenure.

But because it shapes what happens after they leave.

The strongest leaders understand that their role isn’t just to lead the organisation today.

It’s to make sure the organisation is set up to succeed tomorrow.

And that means making succession decisions with clarity, fairness and insight.

The reality is that when leadership transitions are done well, organisations don’t just survive change.

They can thrive. 🔆
