The business enterprise is an object of management because it is being built and operates under the rules and norms established in the legislation of each country. The business enterprise can be also taken up as a subject of economy. The aim of the development is to analyze the peculiarities of the business enterprise, which is an open system made up of system-forming elements implying its integrated development. The methodical instruments used are based on several complementary approaches: a systematic approach and systematic analysis; a structural approach; a logical approach and a synergetic approach. Based on the principles of the systematic approach, we accept that the business enterprise is an “input-output system”. The “business enterprise” system are: production (business), financial and economic, juridical (legal) and social. The synergy between the constituent elements of its internal environment implies not only its integrity, but it is a major prerequisite for its successful integration into the external environment conditions.
