Hofstede (1997) said that culture influence how people behaviour and think, so, it is important to understand culture within an organization; whereas Jim Grieves (2000) strongly supported that organizational development can promote humanistic values, so, earlier in 1982, Deal and Kennedy advocated that organization development should be combined with organizational culture effectively, in order to make people work efficiently.

When we talk about the role of organizational culture in an organization, it is normally better to start from two perspectives which were provided by E. C. Martins and F. Terblanche (2003): the functions of organizational culture and the influence that organizational culture has on the different processes in the organization.

Normally, the functions of organizational culture manifest itself in two aims: first, creating the feeling of identity among personnel and commitment to the organization; second, creating a competitive edge to enable the members (especially new members) in the organization to well understand acceptable behaviour and social system stability (Martins, 2000).

It is the fact that organizational culture can offer a shared system of meanings, which forms the basis of communication and mutual understanding. If the organizational culture doses not fulfill these functions in a satisfactory way, the culture may significantly reduce the efficiency of an organization (Furnham & Gunter, 1993).
