Organizational cultures are very difficult to change and it takes considerable time to do so. The organizational founder and previous experiences of an organization help to establish “how things get done around here”; and these norms, values, and assumptions are often not conscious or easily changed. 

However, cultures are particularly sensitive to the behaviors and attitudes of senior leaders. Therefore, senior leaders do have a special interest and responsibility in reinforcing positive and productive aspects of a culture, and replacing negative and unproductive aspects.
