I like this simple model of self-awareness and understanding your relationship with others. Some things only others can see about you, and to learn about these you need feedback. While others may not realise some things you know about yourself — by sharing or disclosing more, you help others understand more about you. And still other aspects about you, particularly when you are young, may remain unknown to you and others.
Depending on who you’re with, the relative size of each quadrant may be different, for example, if you start on a new team at work.
The examples in the quadrants are as shared with me by Nicola Rowledge.
