It is one of the most common and costly decisions made in Irish businesses every year.

A high-performing employee is promoted into a management role. They are reliable, technically strong, great with clients, and deeply trusted. On paper, it makes perfect sense.

But within a few months, something begins to shift. The team dynamic changes. Results dip. The newly promoted manager feels stretched and uncertain. Frustrations begin to surface across the team, and senior leaders find themselves pulled into people issues they had not anticipated.

So, what went wrong?

The Assumption We Make About Leadership

In many organisations, there is an underlying assumption that strong individual performance naturally translates into leadership capability.
In reality, it rarely does.

This is not a reflection of the individual’s talent or potential. It is simply that leadership requires a fundamentally different skill set.

Being good at your job is about personal performance. Leading others requires the ability to:

• Communicate clearly, especially under pressure
• Build trust and engagement across a team
• Navigate conflict and difficult conversations
• Set expectations and hold people accountable
• Develop others while still managing your own responsibilities

These are all learnable skills but they do not come automatically with a promotion.

What I See in Irish SMEs

In my work with business owners and senior leaders, I see this pattern time and again.

A capable individual is promoted and expected to step into leadership with little or no structured support. In some cases, they may have informal guidance or a strong internal mentor. In many others, they are left to figure it out through experience.
What is often missing is not ability, it’s structure.

And the cost of that gap shows up quickly.

The Real Cost to the Business

When managers are not supported through the transition into leadership, the impact is felt across the organisation:

• Team disengagement, as inconsistency in leadership creates uncertainty
• Increased pressure on senior leaders, who step back into day-to-day people management
• Retention risk, as strong employees disengage or leave under poor leadership
• Impact on performance, where communication breakdowns affect delivery and client relationships

Research consistently shows that people don’t leave companies – they leave managers.

For growing businesses, investing in leadership capability is not a “nice to have”. It is one of the highest return investments you can make.

What Effective Leadership Development Looks Like

What I have found through my work is that leadership development only works when it is structured, practical, and measurable.

It is not about one-off training sessions. It is about creating a consistent shift in how managers lead day to day.

The most effective approach combines:

• A clear framework that defines what good leadership looks like within the business
• Practical tools and techniques for communication, feedback, and performance management
• Ongoing support, including coaching, to embed new behaviours
• Application in real work situations, not just classroom learning
• Measurement of impact, so progress is visible and meaningful

Leadership development should not be an event, it should result in a measurable shift in how managers operate and how their teams perform.

Why Measurement Matters

One of the biggest gaps in leadership development is the absence of meaningful measurement.

Too often, organisations invest in training without a clear way to assess whether it is making a difference.

That is why I build measurement into every programme, not as an add-on, but as a core part of the process.

Before we begin, we define what success looks like. This might include:

• Improvements in manager confidence
• Stronger communication across teams
• Increased engagement
• More effective performance conversations
• Better alignment and accountability

We then track progress against these indicators throughout the programme.

This gives both the individual and the business clarity on what is changing and where further support is needed.

A Question Worth Considering

If you have promoted someone into a leadership role in the last 12 months, it is worth asking:

What structured support did they receive? Was it a one-off course? A handbook? Informal guidance?
Or were they expected to figure it out as they went?

If it is the latter, it is not too late.

With the right structure and support, managers can develop quickly and the impact on the individual, their team, and the wider business can be significant.
