SUMMARY
The timely conversion information-administrative architecture (IAA) gives the enterprise a certain advantages: high competitiveness, increase of controllability of the divisions of the enterprise. When there are models of the dynamics of IAA, qualitative transformations can be conducted. Division of the elementary transformations, the separation of classification features and merging of these transformations in the classes will allow to build a model of the dynamics of IAA. Certain changes, which take place in IAA, relate to the elements, relations, characteristics or properties. These can be more detailed and submit as an orderly or simply set of transformations. Aggregate stages of conversion can be considered at different levels of detail, down to the lowest-level of elementary transformations, that is such, which cannot be identified through a simple transformation. The notion of elementary transformation to a large extent depends on the point of view of the researcher, the goals and tasks of the research. Essential features of elementary is simplicity and constructive. The concept of elementary depends on the level and depends on the layer. At each layer of the managerial component of IAA there are the following classes of elementary transformation: the transformation of objects and the transformation of connections. Any changes IAA can submit superposition of elementary transformations.
