In the world of corporate Learning and Development, there is a set of numbers that almost everyone can recite from memory: 70-20-10.
Developed in the 1980s by researchers at the Centre for Creative Leadership, the model is simple. It suggests that individuals obtain 70% of their knowledge from job-related experiences, 20% from interactions with others (social learning), and a mere 10% from formal educational events and classes.
It is a beautiful, intuitive framework. It acknowledges that humans are experiential learners. Yet, if you look at the average corporate budget, you’ll see a bizarre mathematical paradox. We are obsessed with the 10%.
We spend 90% of our budget on the smallest slice of the pie. We keep hoping that a better workshop, a flashier keynote speaker, or a more expensive three-day retreat will be the magic bullet that finally fixes our management and leadership capability.
But management isn’t a theory you study, and until we stop trying to know our way to leadership and start proactively enabling our teams, our training budgets will continue to be a sunk cost rather than a strategic investment.
The Content Fallacy
The Management Development Myth is the pervasive idea that more content equals better leaders. We treat leadership as if it were an academic subject like history or biology—something that can be mastered by reading enough case studies or watching enough TED-style videos.
But knowledge is not the same as capability. You can watch a thousand videos on how to swing a golf club, but the first time you stand over a ball, you’re still going to slice it into the woods. Why? Because management is a performance-based discipline. It requires muscle memory, emotional regulation, and the ability to react to unpredictable human variables in real-time.
When we dump managers into knowledge-heavy programmes, we aren’t actually developing them; we’re just making them smarter about their own failures. They leave the workshop with a binder full of theories that they have no idea how to apply when a team member breaks down in tears, or a project deadline goes off the rails on a Tuesday morning.
Moving Learning into the Flow of Work
The reason the 70%—the on-the-job experience—is so powerful is that it happens in context. It is just-in-time learning rather than just-in-case learning.
If we want to see a genuine Return on Investment on development budgets, we have to stop pulling people away from work to learn and start moving the learning into the flow of work.
What does this look like? It means shifting the focus from training to embedding. Instead of a one-off seminar on ‘How to Give Feedback’, development should involve small, bite-sized behavioural interventions that a manager performs naturally during their everyday conversations. It means enabling managers to use an Operational Coaching® system—where the act of managing is the act of naturally developing their team in the flow of work.
When learning is divorced from the daily grind, it’s just a nice chat. It’s a pleasant afternoon away from the desk while the real work piles up. But when learning is integrated into the work itself, not only does the manager’s capability improve, but so does the performance of their team.
Management is a Skill, Not a Seminar
Imagine a football team that spent 90% of its season in a classroom looking at playbooks and only 10% of its time on the pitch. They would be the smartest team in the league—and they would lose every single game.
Management is no different. You cannot know your way to being a great manager; you have to practice your way there. You have to have the difficult conversations, navigate the office politics, and learn how to ask the right questions rather than just providing the wrong answers.
This is where the maths goes wrong. By over-indexing on formal training (the 10%), we neglect the support systems required for the 70%. We don’t provide the guardrails, the real-time feedback, or the Operational Coaching® that helps a manager turn a daily challenge into a developmental breakthrough.
The True Cost of the Myth
Why does this myth persist? Because the 10% is easy to measure. You can count heads in a room. You can track completion rates on an LMS. You can see a line item on a budget.
Measuring the 70%—the actual behavioural change happening on the shop floor or in the Zoom room—is much harder. It requires an innovation in how we capture success, and it requires programme design that demands action and reflection, not just learning.
If your management development programme’s primary output is attendance, you are engaged in an academic exercise. If the output is a measurable change in team performance, increases in capability, improved productivity, higher colleague engagement, or a shift in culture and a measurable RoI, you are making a business investment.
It’s time to stop over-funding the 10%. It’s time to stop paying for your colleagues to enjoy a nice lunch in the middle of the workshop and start building a culture that can easily measure the specific improvements in performance as a result of your training budget.
Management isn’t a theory—it’s time we started treating it as the critical, high-stakes skill it actually is.
