authentic
Your company culture is not prescribed by the executive. It is not a strategy from the top down. It is the experience and brand that your employees live and breath every day. Through them it is the experience and brand your customers learn to love. Your purpose-driven values only live through the authenticity of the culture that holds them.
This is not in the control of the leadership, but it can be enhanced, codified and grown with support from leadership. A strong culture will fuel your employee engagement making them employees for life (even if they aren't on payroll). It will cut oxygen off to your competitors and bring you the best talent. It will help your business thrive, differentiate your services and products, and make your customers, customers for life.
