Transforming a company's culture is important for improving performance but cannot be done without changing the shared values and attitudes of its members. To change a culture, a company must establish key values, change individual behaviors, and create a creative and entrepreneurial climate instead of bureaucracy. Jack Welch transformed GE's culture by establishing values of reality, candor, and integrity which he said were essential for competitive success. He spent years developing a values statement with 5,000 employees to define the expected attitudes and behaviors. As more managers tried to embody these values, it changed GE's culture for the better.
