Learning by Doing: Why On-the-Job Learning Beats Courses

Learning by Doing: Why On-the-Job Learning Beats Courses

Most workplace learning does not work.

Not because the content is poor or the facilitators are bad. But because most workplace learning is built on a mistaken assumption: that consuming information is the same as developing capability.

It is not.

There is a real and important difference between knowing about something and being able to do it. Between understanding a model and applying it under pressure. Between reciting a framework and knowing what to do when it does not work in practice.

This distinction matters enormously for how organisations approach learning and development — and for how individuals approach their own growth.

Two modes of learning

Over many years, I have come to believe that most workplace learning falls into two broad modes. Understanding the difference between them — and how to combine them — changes what learning actually produces.

Information Acquisition

The first is information acquisition.

This is the consumption of information: reading books, attending courses, watching videos, capturing notes, building knowledge systems. It is the pursuit of understanding and recall — knowing about something.

Information acquisition has genuine value. It provides language, models, and perspective. It helps you recognise patterns and understand principles. But on its own, it rarely changes how work actually gets done.

I see this regularly in consulting. There are people in this industry who spout information they have never tested — management theory they have never managed with, agile frameworks they have deployed without ever experiencing what happens when they do not work. They know more than their clients, for now, and that carries them. At some point, information alone stops being sufficient.

The most striking example: you can read every book ever written on drumming, learn the theory, understand the principles, and be able to explain them clearly to others. And yet you still cannot play the drums. Information about drumming and the ability to drum are genuinely different things.

Task Acquisition

The second is task acquisition — learning by doing.

Task acquisition is the act of performing the work itself and getting better through repetition, reflection, and adjustment. The photographer who learns by shooting. The manager who learns by managing. The business owner who learns by running the business, day after day, through the problems and pressures that no course can fully simulate.

This is experiential learning: powerful because it is grounded in reality. Consequences are immediate. Feedback is unavoidable. Behaviour is shaped by experience rather than explanation.

In work, I almost always start here. Given a choice between attending a training course on management and managing — with support and feedback — I will recommend managing every time.

Task acquisition has limits too, however. Without reflection, people can repeat the same mistakes with increasing confidence. Experience becomes habit rather than improvement. This is why the two modes need each other.

The power of combining them

Information sharpens practice. Practice tests information.

You take ideas into the work, try them, and notice what holds up and what collapses under real conditions. Sometimes you start with information and discover its limits through action. Other times you start with action and find that new information would help you improve further. Either direction works.

The PKMS process — capture, curate, crunch, contribute — exists precisely to support this loop. The crunch step is where information meets action: taking something you have read or learned, testing it in practice, and adjusting based on what actually happens. That is where information becomes knowledge.

The third and most powerful layer: teaching

When someone learning a task is paired with someone already excellent at it, learning becomes visible, guided, and faster.

This is on-the-job learning in its purest form. The work is real. The feedback is immediate. The standards are clear. The learner sees what good actually looks like, in context, not as a slide or a video but as something observable and discussable.

All managers are teachers, whether they recognise it or not. Every time a manager demonstrates how to handle a difficult conversation, how to structure a decision, how to staple themselves to the work and understand a system — they are teaching. The question is only whether they are doing it deliberately.

When teaching happens alongside real work rather than in a classroom separated from it, behaviour changes far more reliably than any course can produce. This is how capability actually grows in organisations: not by sending people away to learn, but by supporting them while they do the work.

What this means in practice

For individuals: prioritise doing over consuming. Read to inform your practice, not to substitute for it. Find someone further ahead than you and work alongside them. Reflect on what you try. Adjust.

For managers: treat development as something that happens in the flow of work, not as a separate event. Pair people deliberately. Coach in the moment. Model the standard you want, because people are watching and learning from you whether you intend it or not.

For organisations: measure learning by behaviour change, not course completion. Training that does not change how people work is not learning — it is content consumption with a certificate at the end.

The most effective learning cultures are those where people are encouraged to try, supported to reflect, and guided by those who have already walked the path.

Because learning only matters when it shows up in what people actually do.

And that is where value is created.
