The 70:20:10 rule is commonly quoted, as in this video by Steve Trautman, as representing the three ways in which people learn.
- 10% of our learning, comes from formal training
- 20% of our learning comes from mentoring or formal knowledge transfer, from a senior to a junior, or teacher to learner
- 70% of our learning comes "On the job".
In the video, Steve suggests that this on-the-job learning happens by osmosis. However the use of Knowledge Management can deliver on-the-job leaning in a far more effective way than just osmosis.
- Reflective team learning practices such as After Action Review and Retrospect allow people to discuss what have been learned, and become conscious of learning, thus accelerating personal learning.
- Good knowledge bases form an explicit learning resource for people to learn on the job.
- A community of practice forms a tacit learning resource for people to lean on the job.
A combination of formal learning and development, mentoring programs and Knowledge Management therefore cover the entire 100% spectrum of learning.
