7 Pillars - Self Assessment

A moment to learn, a lifetime to master

[0] Questioning - not sure what this is [1] Learning - I know it but have no 1st hand experience [2] Practicing - I actively use it. I can reference more than one resource I‘ve used to learn this skill. I used it within the last 30 days. [3] Journeying - Used skill in multiple environments. Peers from 2 different environments recognize person‘s competence. [4] Mastering - Unquestioned competence. Can explain underlying forces. Practiced skill along side other experts.

Socialization Combination

Internalization

Externalization

Conversion Pattern • Leads to new knowledge

Ba • The place which makes a particular

conversion happen
