Organizational culture was traditionally seen as something that could be controlled by executives, but is now viewed as a deeper set of shared assumptions that are not easily changed. Culture exists below the surface like an iceberg and is influenced more by everyday experiences than direct management. When seeking to change culture, it is important to determine if compliance with new approaches is genuine or resigned, and if changes are only superficial or reflect deeper shifts in underlying values and behaviors. Effective cultural change involves understanding what can influence culture and why change is needed rather than just how to change.
