Business model - is a graphic description of the business processes, showing the actual current or prospective activities of the organization. In the simplest case, the business model may include a single diagram, in practice this is impossible because the business processes are generally too complicated and ambiguous.

The main objectives of the business process modeling are formulated as:

• ensuring knowledge of the structure of the organization and dynamics of the processes occurring in it;

• Ensuring knowledge current problems and opportunities for the organization to address them;

• make sure that customers, users and developers alike aware of the purpose and objectives of the organization;

• provide a basis for the formation of requirements for software that automates business processes of the organization.

The main field of application of business simulation - a reorganization of the business processes. It is supposed to build models of present and future activities, as well as the plan and program of transition from the first state to the second. Any modern enterprise is a complex organized system, its activities include the performance of a variety of mutually influencing the functions and operations. Man is not able to immediately understand how this system works in detail - it is very difficult to understand and imagine. Therefore, the main idea of ​​creating a so-called model «ASIS» (as is) and «AS TO BE» (as it should be) - it is an understanding that does or does (will do) the organization and how it works (will work) to achieve their goals . The purpose of the future system software is, first of all, the solution of business problems using modern information technologies. Software requirements are formed on the basis of the business model and system design criteria are primarily based on the fullest satisfaction.

It should be noted that the business process models are not merely the result of an intermediate used a consultant to produce any recommendations and conclusions. They are the result of self, which is of great practical importance, which follows from the objectives of their construction.

SADT method (Structured Analysis and DesignTechnique) - is considered a classic by the process approach to management. The basic principle of process approach consists in structuring the organization of activities in accordance with its business processes, rather than the organizational staff structure. As the business processes that are important to the consumer, it is of value, and it will improve them in the future to deal with. A model based on organizational staff structure, can only show the chaos that occurs in an organization (which, in principle, the management and so it is known, otherwise it would not have initiated relevant work), based on this, you can only make suggestions to change this structure. On the other hand, a model based on business processes, contains the organizational and staff structure of the enterprise. In accordance with the business model of this principle should be as follows:

1.Verhny level model should show the context of the system - the only interaction between the simulated context process of the organization to external factors.

2. On the second level of the model should be shown the main activities (grouped thematically business processes) and their relationship to enterprises. In case of large amounts of some of them can be taken out on the third level model. But in any case, under the activities must be removed no more than two levels of the model.

3.Dalneyshaya detailing business processes carried out by the business functions - set of operations that are grouped according to certain characteristics. Business functions are detailed by elementary business operations.

4.Opisanie elementary business operations carried out by setting the algorithm of its implementation.

SADT method developed by Douglas Ross (SoftTech, Inc.) in 1969 for modeling artificial systems of average complexity. This method has been successfully used in military, industrial and commercial organizations of the USA for a wide range of applications such as long-term and strategic planning, computer-aided manufacturing and design, development of software for defense systems, financial management and logistics, and others. SADT method is supported by the Ministry of US Department of defense, which was the initiator of the development of IDEF family of standards (The Icam Definition), which is the main part of the program ICAM (integrated computerization of production), initiated by the US Air Force. SADT method is implemented in one of the standards of this family - IDEF0, which was approved as a federal standard of the USA in 1993, his detailed specifications can be found on the site There is also a Russian version of the standard [RD2000]. Together with the standard IDEF0 IDEF3 commonly used process modeling standard and IDEF1H.Metod SADT modeling data standard is a set of rules and procedures designed to build a functional model of the object any subject area. Functional SADT model shows the functional structure of the object, ie, actions and communication between the activities performed by them. The main elements of this method is based on the following concepts:

• Graphical representation of block modeling. Graphic blocks and arches SADT diagram shows a function block, and input / output interfaces are represented by arcs, respectively, included in the unit and out of it. Interaction of the blocks with each other is described by the interface arches, express "restrictions" which, in turn, determine how and when functions are executed and controlled.

• The rigor and accuracy. Implementation rules requires sufficient SADT rigor without imposing at the same time undue constraints on action A.M.Vendr analyst. SADT rules include limiting the number of blocks in each level of decomposition (usually 3 or 6 units - power limitation of human short-term memory), charts the connection (block numbers), unique tags and titles (no duplicate names), the syntax rules for graphics (blocks and arcs ), a division of the inputs and controls (typically define the role of data).
