70:20:10 is a straightforward formula created in the 1980’s to describe the sources of successful learning experiences. 70:20:10 represents the ratio of knowledge obtained from three sources:

Job-related experiences (70%) i.e. Observational, what actually occurs.

Interactions with others (20%) i.e. On-the-job instructions, semi-formal on-site training.

– Formal education events (10%) i.e. Classroom instruction.

Messages? You can “train” all you want, but what your Team Members find when they actually get out in the field will tend to overpower any formal training. In other words, your culture is what habitually happens at the front line, not the fancy words in power point in the classroom.

“Culture Trumps Strategy, Every Time. If strategy conflicts with how people already believe, behave or make decisions, it will fail. Conversely, a culturally robust team can turn a so-so strategy into a winner.– Nilofer Merchant 

While 70:20:10 is based upon self-reported belief systems of a relatively small number of executives, it is intuitively appealing.
