In the context of Vietnam’s education and workforce development increasingly shifting toward practical orientation and entrepreneurship, the 70-20-10 model is often referred to as a “golden formula” for learning and competency development.
According to this model, 70% of learning comes from practical experience (on-the-job learning), 20% from social interaction (mentoring, coaching, feedback), and only 10% from formal training (courses, workshops) (Litmos, 2026).
However, behind its appealing premise lie significant scientific challenges: the “70% experiential learning” component is often unstructured, while the three elements lack strong integration, leading to a situation where people learn a lot but struggle to apply it—resulting in a subtle yet widespread waste of resources across both educational institutions and businesses.
Theoretical Foundations and Scientific Limitations
The 70-20-10 model originated from research conducted in the 1980s by Morgan McCall, Michael Lombardo, and Robert Eichinger at the Center for Creative Leadership. The researchers surveyed around 200 successful business leaders, asking them to self-assess the sources of knowledge and skills that contributed to their career advancement. The findings were synthesized into the 70-20-10 ratio, which was later widely popularized by Charles Jennings and Jay Cross through the concept of “informal learning” (Docebo, 2026).
However, at its core, the model is more of a reference framework than a rigid scientific law. Many experts have strongly criticized it: the data relies solely on self-reports from already successful individuals, lacks a control group, has no longitudinal empirical observation, and cannot be generalized. In 2012, Kajewski and Masden (DeakinPrime) asserted that there is a “lack of empirical evidence supporting the 70-20-10 model” (Kajewski, K., & Madsen, V., 2013).
By 2018, the first qualitative study published in Human Resource Development Quarterly (by Johnson, Blackman, and Buick), which surveyed mid-level managers in the Australian public sector, clearly showed that the model fails in practice due to four common misconceptions (Johnson, M., Blackman, D., & Buick, F., 2018).
Core Challenges of the “70% Experiential Learning” Component
The 70% component—hailed as the core—is its greatest weakness.
The 70% component—hailed as the core—is its greatest weakness. Experiential learning is only effective when it is structured, supported by timely feedback, and guided by systematic reflection mechanisms.
In practice, across most organizations and educational programs, experiential learning is often unstructured and poorly managed. Employees or students are “thrown” into real work with the expectation that they will learn on their own, yet they lack preparation, supporting resources, and regular evaluation. As a result, they may internalize incorrect behaviors, repeat mistakes, or simply “work” rather than truly “learn through work.”
The 2018 study concluded that the “overconfident assumption that unstructured experiential learning will automatically lead to capability development” is one of the four critical implementation pitfalls (Johnson, M., Blackman, D., & Buick, F., 2018). In the Vietnamese context, particularly in the post-pandemic era when remote work has become widespread, the challenge is even greater. Phan Sơn warned that without maintaining online training, learning videos, and regular knowledge-sharing, “the 70-20-10 model will disappear.” (Quỳnh Chi, 2021).
Moreover, leaders and educators are often too busy to dedicate time to reflection, synthesis, and experimentation—essential conditions for transforming experience into real capability.
The Waste of “10%–20%–70%” Due to Lack of Integration
The key point that many training programs overlook is integration. The three components are not separate “silos” but should function as a unified system. When integration is lacking:
The 10% of formal training becomes “dead” knowledge on paper: students complete entrepreneurship courses, MBAs, or certifications but lack mentoring (20%) to apply what they’ve learned and real projects (70%) to experiment with—resulting in complete waste.
The 20% of social interaction is reduced to random conversations, lacking structured mentoring or goal-oriented coaching.
The 70% experiential component becomes chaotic, lacking theoretical grounding and feedback to provide direction.
The result is the “knowing–doing gap”—the disconnect between what people know and what they can actually do—a challenge faced by many students, graduates, and young entrepreneurs in Vietnam. They participate in numerous workshops, hackathons, and startup incubation programs (often with ambitious strategies), yet struggle to apply their knowledge in real-world contexts. While the strategies may appear impressive, execution remains highly challenging due to the lack of integration among the three components.
While the strategies may appear impressive, execution remains highly challenging due to the lack of integration among the three components.
The 2018 study clearly identified four key implementation pitfalls: (1) assuming that experience is inherently effective; (2) narrowly interpreting the role of social learning; (3) expecting behavior change to occur automatically after training; and (4) lacking a plan to integrate the three components (Johnson, M., Blackman, D., & Buick, F., 2018). This is the scientific explanation for why many capability development programs in Vietnam, despite significant investment, still deliver limited results.
Lessons for Education and Entrepreneurship in Vietnam
In Vietnam, higher education and startup support programs are increasingly shifting toward a more practice-oriented approach. However, if we focus solely on strengthening the “70% experiential learning” without building high-quality mentoring systems and well-integrated formal training pathways, we will continue to waste intellectual resources. Young entrepreneurs learn a great deal but apply little, while graduates possess theoretical knowledge yet lack practical, hands-on skills.
The solution does not lie in changing the percentages, but in adopting a systems design mindset:
Design structured experiential learning with clear objectives, regular reflection, and evaluation.
Integrate mentoring/coaching as a critical bridge between theory and practice.
Develop a learning journey in which all three components reinforce one another rather than operate in isolation.
Only by addressing these four misconceptions can the 70-20-10 model truly become an effective tool, rather than a compelling but ineffective slogan.
In an era where knowledge is abundant but application remains limited, the key lesson is not to learn more, but to connect learning more intelligently
In summary, the 70-20-10 model is not inherently flawed, but the way we interpret and implement it has created significant scientific challenges. In an era where knowledge is abundant but application remains limited, the key lesson is not to learn more, but to connect learning more intelligently. Only when the three components—10, 20, and 70—function as an integrated system can ambitious strategies truly translate into sustainable capability, something both the education system and the entrepreneurial community in Vietnam urgently need.
RespectVN: "Learning outcomes must be directly integrated into Performance Management to avoid resource waste and stay true to the core essence of the 70-20-10 model."
We believe that if learning and practice are not measured, evaluated, and linked to performance management systems, then that 70% remains a cost rather than an investment.
Therefore, RespectVN advocates transforming the entire learning journey into measurable indicators that can be tracked and clearly reflected in individual KPIs and organizational business outcomes.
In this context, Ms Ha Dang, Founder of RespectVN, has pioneered the practical experimentation and application of a 12-indicator L&D framework integrated into the Balanced Scorecard. This framework is designed to help organizations implement learning strategies more effectively through four clear strategic perspectives: Financial (impact on financial performance), Customer (customer satisfaction and service capability), Internal Process (process improvement), and Learning & Growth (sustainable human development).
With this BSC framework, the “70% experiential learning” component is no longer a fragmented activity but becomes an integral part of the performance management system, ensuring that every learning effort generates measurable value and directly contributes to business objectives.
With this integrated approach, RespectVN is committed to partnering with Vietnamese businesses to build a culture of learning–action–measurement–continuous improvement, transforming L&D from a cost center into a driver of sustainable growth and a clear competitive advantage.
FLASHBACK RESPECTVN'S JOURNEY
RespectVN has redefined L&D from a supporting function into a core driver of business value, developing a 12-indicator system directly linked to organizational performance, while integrating OKRs and the Business Model Canvas into a “Made in Vietnam” model.
At the same time, it has been implemented across more than 50 enterprises, driving a shift in management mindset—transforming learning into a lever for growth rather than merely a training activity.
"We aim to answer a fundamental question: how should organizations approach learning and development in ways that directly impact business priorities, especially in addressing the critical challenges they face today.
The goal is to ensure that everyone in the organization—from leadership to frontline employees—shares a common understanding that learning and development is critically important."
There are no great organizations. There are only great people who make great organizations"
