The thesis is based on the theoretical overview, as well as the practical examples of organization and communication within the organization, and their role in today's global society. As an extremely important segment of our lives, organization eases the performance of the most complicated tasks. An organization is defined as a conscious activity carried out and maintained by people's will in order to create a whole from the mass. Organizations keep track of a human being from the moment he is born, up to his death, wherein every aspect of life is connected with the organization. Within organizations, people do certain tasks together, which they would not be able to do independently, as a means of achieving a certain common goal. In today's turbulent business environment, organizations are confronted with constant changes, which denote the acceptance of new ideas or behaviors of the organization. Each of these changes carries a certain risk and uncertainty, but these changes are necessary for the organization to be able to respond to customer's needs, as well as technological changes and government measures. Communication has an important role within each organization. No organization can withstand without an effective communication. Communication is an exchange of information from the sender to the recipient, with the condition that the recipient understands the information which represents the basis of the communication process. The communicational process involves a sender, coding, a message, channels, decoding, a recipient, and feedback. Business communication helps an organization to function better and to achieve success on their business plan. Good communication between the staff, but also to the public, leads organizations to work more efficiently, and to the main goal of most organizations, profit.
