This paper will describe the manager as an employee of the company, its characteristics and the skills it needs to perform the tasks that are required of it. A manager is a person who is in most cases a leader and is responsible for the work done by his associates and therefore requires them to have developed management skills in order to guide people in the organization. It is not enough just to acquire one or all managerial skills at once, but it is necessary to continuously develop through work. They do not have all the managers of innate abilities, so sometimes it takes a lot more time to get them through doing business. Speaking of the decision-making process, this paper describes the notion of self-determination, the conditions in which decision makers are located, the prerequisites required to be met in order to make the best decision and the steps that need to be taken to reach a final decision. Since there are many choices, so each one is self-specific and has various characteristics that this work will also explain. Emphasis will be placed on communication as one of the most important features that managers need. This chapter will highlight the importance of communication throughout the organization, the importance of communication among associates in order to create a comfortable atmosphere in which to work and the most important principles to be met to be able to say that business communication has been successfully carried out.
