System aspects of interaction of spatial structures of the city

Ctivities of all managing directors, irrespective of where they are busy: in commercial enterprise, government, municipal department or university, takes place in fixed interaction with the external environment. In spite of the fact that managing directors only in insignificant degree can influence the external environment (or isn’t able to do it at all), they can’t ignore it, are obliged to react to it adequately. Undoubtedly, managing directors can react when changes in the surrounding external environment are already obvious, but it is much better to expect these changes. For simplification of identification of the sectors of the external environment exerting a certain impact on all types of the entities we classify them as economic, technological, social, political and ethical. Of course, this classification mild. Buyers are the most important factor in the economic activity of commercial enterprises turned outside. Without consumers the business company can’t simply exist. For successful performance the entity shall in every possible way aim to learn that people want and are ready to purchase. Business activity of the entity was always determined by the relative level of its technologies. If the commercial enterprise isn’t aware of the last technological achievements which can be used as in a production process of goods and the provided services, and for enhancement of methods of work, then it in a considerable measure is doomed to failure, especially in the conditions of a fierce competition.
