<u>Explanation:</u>

The values that are followed by an organisation and their expectations about the behavior of its members refers to the organisation culture. It encapsulates the behavior of an individual in an organisation and his behavior with the other people and the society. The beliefs and the values that exits in an organisation refers to its culture.

Culture is very important for an organisation to project its image to the outside world. Thus, an organisations's culture can be viewed as the personality of an organisation. Thus, the traits of personality of an individual can be compared with the personality of an organisation which is its culture.
