Digitizing a thought I had written in a journal back in 2010 around the idea of a Centre of Influence (COI). I had defined COIs as those people we have relationships with who possess a level of influence over our decision-making. The influence is exerted by virtue of their primary relationship dynamic with their network. These are people trusted & networked as an influencer, and their advice is often taken with little further thought.
It's apparent that my then knowledge of personal/professional relationship dynamics was much more limited than it is today, but interesting nonetheless...
