Documenting what works and what doesn't, and then sharing that information, builds a culture where people learn from each other. Culture has to be about people. People are the most important thing. When you feel important, respected, cared about, you are open to learning. Culture is the rituals, the interpretations, the way in which we act around events.
Culture is who the organization is.
How everyone interacts and reacts to the good, the bad and the truly ugly defines culture. Organizations are patterns of conversations, interactions and relationships that is what determines culture. Culture is the overriding context in which we work. Good culture can be a sustainable competitive advantage to gaining and retaining talent. People came to our company because of our vision and a culture that let them apply value to that vision with their talent.
