what is culture? “A pattern of shared tacit assumptions that was learned by a group as it solved its problems of external adaptation and internal integration, that has worked well enough to be considered valid and, therefore, to be taught to new members as the correct way to perceive, think, and feel in relation to those problems.” — Edgar Schein, The Corporate Culture Survival Guide

what is culture? “Our true culture is made primarily of the things no one will say... Culture is about power dynamics, unspoken priorities and beliefs, mythologies, conﬂicts, enforcement of social norms, creation of in/out groups and distribution of wealth and control inside companies.” — Shanley Kane | @shanley | Your Startup Is Broken: Inside the Toxic Heart of Tech Culture

“I think building this culture is the key to innovation. Creativity must ﬂow from everywhere. Whether you are a summer intern or the CTO, any good idea must be able to seek an objective test, preferably a test that exposes the idea to real customers. Everyone must be able to experiment, learn, and iterate.” innovation culture http://glinden.blogspot.com/2006/04/early-amazon-shopping-cart.html
