The basis of business processes is business communication. Determining the purpose of communication, the choice of style of communication, the structure elaboration, the choice of communication channel and the media, and analysis of the listeners or readers of messages are activities of business communication planning. Communication achieves certain goals and it is very important for it to be successful. In communication important place take communication subjects, sender and recipient, and communication becomes essence of life. In order to create trust and community between employees, communication is needed. Designed and well organized network of formal and informal communications in the organization is important prerequisite for reducing uncertainty (ambiguity). Organizational communication includes speech and writing, business meetings, reports, inquiries and offers, but it also includes messages that are transmitted by words, but without words. There are direct and indirect spoken business communications. Direct is considered face-to-face conversation, telephone conversation, meeting and presentation, while voice messages are indirect spoken business communications. Written business communications can be performed in paper (business letters and memos) or electronic form (e-mail, web, chat). Such business communication is always planned to allow the message to be processed to the smallest details, but slower than verbal communication due to longer feedback time. People communicate and when they are not aware of it, by the expressions of faces, messages, drawings, or posture, and such communication is called nonverbal communication. The main problem in the communication process is to define user requirements. The user often does not know what to do and how to do it, even though he knows his job.
