Culture as learned solutions
He defines culture as the accumulated solutions a group learned that worked well enough to be taught as correct. Because it is the residue of past success, culture resists change precisely because it once solved real problems.
Change means unlearning first
Schein argues transformation requires creating psychological safety while introducing survival anxiety, so people can unlearn old assumptions. Culture change is managed as a guided relearning, not an imposed mandate.
