Schein: ‘Culture is a pattern of basic assumptions, invented, discovered, or developed by a given group, as it learns to cope with its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, is to be taught to new members as the correct way to perceive, think, and feel in relation to those problems.’
This is a perfect definition for working with #GameChangingBeliefs.
Thank you Eva Stenby Carlsen for pointing this out and helping with the specific reference: Schein, E.H. (1990). Organizational culture, (American Psychologist, 45(2), 109-119)
