Culture is not mission, vision, values. It is not architecture, design, product or snacks. It is also not the lighting, furniture, games, attire, or flextime.
Mistaking any of these things for culture is to confuse the map with the territory.
Culture is how you and your colleagues come together to solve problems under the pressure and stress of change.
If any of the items above help you to do that well, use them. If they don’t, let them go as fast as you can.
