This chapter will explain, in light of the methodology network of trustfulness (MNT), the existence of a series of factors that explain a higher percentage of organizational culture in terms of values and beliefs, which developed and deployed by senior management become fundamental aspects for their flourishing and maintenance, on which management expects its workers to express in their day-to-day behavior. The hypothesis raised in the title of this chapter is fully verified to the extent that from the multiple regression analysis, the results between the dependent variable (values and beliefs as direct definers of organizational culture) and the 17 independent variables that make up the model show that they explain 58-59% of the organizational culture.
