Organizational culture acts as a social control system (Bate, 2000) and managers get a more complete awareness
of the atmosphere governing over organization, organization’s strengths and weaknesses; and identify and apply
required strategy and policies (Kwantes & Boglarsky, 2007; Zheng, Yang, & McLean, 2010). By a strong and
coherent culture, individuals are aware of the organization goals and strategies and feel responsible in relation to
values and norms and finally results in the commitment and job satisfaction (Chan, Shaffer, & Snape, 2004).
After considering other methods of investigating organizational culture, the authors decided that to use Denison's
model for this study. The reasons why we choose this model is that, because this is more modern than previous
models, it is based on behavior, it can be used at all levels of or the organization its indexes of measurement are
complete and it evaluates different model is its graphic diagram that specifies features of organizational culture
in 12 indices, Also it contains two vertical and horizontal axis that dived this model into four quadrants. Vertical
axis contains degree and kind of organizational culture, this axis ends at one side to External focus and at the
other end to internal focus. The horizontal axis shows the flexibility of the organization.
