Let’s be honest.

You’ve sat in training sessions and your team has too. There’s usually a burst of energy at the start - some good ideas, a few notes written down, maybe even a sense that things will be different this time.

But then reality kicks back in. The day-to-day takes over, priorities shift and within a short space of time… nothing really changes.

This isn’t a reflection of your people. It’s not about effort, intelligence or even motivation. It’s about the system you’re relying on. And the uncomfortable truth is this:

Most training doesn’t work.

Not occasionally. Not slightly. But in a consistent, predictable way.

Within 24 hours, people forget up to 75% of what they’ve learned. And of the small amount that remains, as much as 85 - 90% is never actually applied in the workplace. So when training fails to deliver results, it’s not surprising - it’s exactly what the current model is designed to produce.

The real problem isn’t training - it’s what happens after

There are two core reasons why training fails and both are built into how most organisations approach development.

The first is the retention problem. People forget, and they forget quickly. Without reinforcement, repetition, or structured follow-up, most learning fades within days. This isn’t a matter of discipline or engagement - it’s simply how the human brain works. One-off training sessions assume that exposure is enough, but exposure alone doesn’t create lasting memory.

The second is the transfer problem. Even when people do remember what they’ve learned, they often don’t apply it. Research shows that only 10 - 15% of training translates into real, sustained behaviour change in the workplace.

This happens because the environment people return to doesn’t support change. Managers don’t consistently reinforce new behaviours. There’s often no time or opportunity to practise new skills. In many cases, old behaviours are still rewarded, while new ones are ignored. Without ongoing support, even the most motivated employees fall back into familiar patterns.

This is what it’s actually costing you

When you combine these two problems, the impact is significant.

If around 30% of learning is retained after a day, and only 15% of that is ever applied, you’re left with just 4.5% effective behaviour change. In practical terms, that means for every £100,000 spent on training, only £4,500 creates any meaningful, lasting impact.

The rest is lost.

Globally, this adds up to billions in wasted investment every year. But the financial cost is only part of the story. There’s also the frustration of seeing little return, the stagnation that comes from lack of progress, and the missed opportunity to truly develop your team.

Why fixing just one part doesn’t work

Many organisations try to improve outcomes by focusing on the training itself. They invest in better content, more engaging delivery, or higher-quality facilitators.

While this can improve the experience, it doesn’t solve the underlying problem.

If you focus only on retention, people may remember more - but they still won’t apply it. If you focus only on transfer, you create an environment for change - but there’s little retained knowledge to apply in the first place.

Addressing just one side of the equation still leads to failure.

What actually works: a system, not an event

To get real results, you need to address both retention and transfer at the same time. That requires a shift in thinking - from viewing training as a one-off event to building a system for ongoing development.

This system is built on three core components.

Training remains important, but its role is to provide foundational knowledge. It should be simple, clear, and reinforced over time rather than delivered in a single burst.

Mentoring is what turns that knowledge into practical skill. Through guidance, feedback, and real-world application, people begin to integrate what they’ve learned into how they actually work.

Coaching is what drives performance. It creates accountability, challenges thinking, and helps individuals unlock their potential. Research consistently shows that when coaching is added to training, the impact increases dramatically - often multiplying performance improvements several times over.

When you combine all three, everything changes

When retention and transfer are both addressed through a structured system, the results are fundamentally different.

Knowledge sticks because it’s reinforced. Behaviour changes because it’s supported. Performance improves because individuals are developed, not just instructed.

Instead of seeing minimal impact from training, organisations can achieve upwards of 80% meaningful behaviour change.

This isn’t a small improvement. It’s a complete shift in outcomes.

What this means for your practice

If your team isn’t growing in the way you want, it’s worth asking whether the issue is really capability - or whether it’s the system they’re operating within.

Many practices find themselves stuck in what we call the Tasks Cycle. This is where leaders are constantly firefighting, taking on too much responsibility, and focusing on getting through the day rather than developing their people. It often leads to pressure, burnout, and limited long-term growth.

The alternative is the People Cycle. In this environment, teams are empowered, responsibility is shared, and development is built into how the business operates. The result is stronger performance, greater engagement, and more sustainable growth.

The difference between these two isn’t how hard people work. It’s how the system is designed.

What to do next

Before making changes, the most important step is understanding where you are now.

Are you operating in a Tasks Cycle, or a People Cycle?

We’ve created a short diagnostic tool to help you answer that question. It takes less than five minutes to complete and provides a clear picture of your current position, along with guidance on what to focus on next.

Take the People vs Tasks Diagnostic

If you want to understand why your team isn’t growing - and what to do about it - the diagnostic is the best place to start.

Once you can clearly see the system you’re operating in, you’re in a position to change it - and that’s where real progress begins.
