It constitutes what is expected and accepted with regard to human performance. The culture of an organization is greatly influenced by its early founders. Executives, managers, and supervisors change it over time for better or worse. A good and appropriate culture is the key to success and survival for any company. The responsibility for creating, maintaining, changing, and monitoring organizational culture lies with the CEO, Board of Directors, and other senior executives.
Different companies have different cultures, hidden cultures, and sub-cultures.
In successful organizations, top executives serve as role models for others to emulate. They mold the culture to what is appropriate through a mission, vision, expectations, measures, rewards, and policies. These are supposed to be communicated and understood from top to bottom in the organization. It is not unusual to find that the leaders of a company are saying one thing, and its people at the middle and bottom of the organization are saying or doing another. Changing the culture involves vision, risk, commitment, and a lot of patience.
