The best 70-20-10 is Gordon Ramsey's ratio for the perfect burger
70% chuck steak
20% short rib
10% fat (finely ground)
The other 70-20-10 framework is built on the belief that
70% of workplace learning should, come from on the job learning
20% should be enabled by learning directly from others; and
10% of workplace learning should be formal training;
Nice model, except there is no significant evidence that 70-20-10 works in practice - it is (at time of writing in 2024) only a theory upheld by one limited study
However as this is a "best things I learned in training" post I wanted to defend 70-20-10 to an extent
It feels right
get the theory in a classroom
get coaching or mentoring and
apply the lessons on the job to see what works and what doesn't
It is a non scientific reminder that skill, environment and motivation all play a role in how we learn
Take time to learn skills properly in a controlled environment, get feedback from those around you and practice, get feedback, adjust, practice, adjust, get feedback until you reach the required standard.... On that path lies excellence!
