The success of the organization is based on successful communication. There is no organization without communication, but there are organizations with poor communication. Corporate or business communication is considered a conscious, organized, planned and designed process of conveying business messages between sender and receiver. Internal (internal) corporate communication implies downward and upward vertical communication (between higher and lower organizational levels) and horizontal and lateral communication (between employees). People within the organization and in general differ from each other, which is why each organization has its own specific characteristics. The common characteristics of all organizations are the name, set goals, implemented rules, adequate structure, position, chain of authority, power, reports, employees and set boundaries in the organization. Organizational culture is observed in the form of a general pattern of behavior, shared beliefs, and values of employees within the organization. Organizational culture consists of the beliefs, attitudes and opinions of employees within the organization. Each organization, under global macro-cultural conditions, develops its own specific culture that employees must accept. Acceptance of organizational culture is a condition for the survival, work and success of employees, teams and other groups within the organization. Organizational culture is an important determinant of corporate communication in an organization because it determines its strategy, style and content with a goal of achieving positive business results.
