Each organism during its activity is undergoing certain phases that marks its existence. In the same way, every organization begins its market path starting with the establishment and ending with the shutdown of the whole organization. For this very reason, the purpose of this paper is to present the organization itself and its structure through all phases of its life span. The life-cycle theory of the organization has changed in history and in relation to different authors, so the results of different researches are presented, whose contributions have influenced the final formation of the organization's life-longing theory. The importance of these lies in the fact that on these foundations, the life-style settings of contemporary organizations characterized by action under extremely dynamic market conditions were also built. Also, the structure of the organization itself needs to be defined in accordance with the individual phase of life. Each organization, in the first place, adjusts to changes in life cycle phases, so it differs greatly in entrepreneurial phases at the beginning of business, developmental phases of the collective spirit and formalization, and eventually in the organization's stage of elaboration. Various methods, such as synthesis, compilation, and deduction, have been used to analyze the available literature, resulting in valuable conclusions and laying the foundations for further exploration of this area.
