Reinforce what resonates with cultural values

Promoting individual expression and subcultures doesn't mean free for all. Everyone should still enjoy it in the end. CEOs should encourage projects or ideas that align with company values. A CEO should communicate what works and what doesn't.

When the boundaries for culture and subculture are clear, it boils down to patience. A strong culture will be self-monitoring. But if something or someone doesn't mix well with the company values, it is easily seen in conflict or problems.
