In the business modeling development history, there are four stages based on a conceptual approach to the organization management (Figure 1.1).

At the first stage of business modeling development, the implementation of large-scale projects in various activity fields began. There has been a change in the production conditions of commercial and manufacturing companies, which has led to a number of problems arising in the organization activities. The problem analysis revealed disadvantages in the work of the organizational and technical system, which provides for the work of personnel, equipment, software and ways of their interaction.

Therefore, it was proposed to develop adequate ways of interconnecting the presented elements. The most well—known methodology is the structural analysis methodology and design of SADT systems, which was developed by Douglas Ross in 1973.

In the second stage, the development of enterprises activities describing methods gained popularity, due to the widespread introduction of personal computers and the development of information systems. The most popular organization describing methodologies at this time are modeling using data flow diagrams of various notations, developed by Jordan De Mark and Gainar-Sarson, information modeling by Chen Barker using entity-relationship diagrams, modeling of business processes of EPC notation, dynamic, functional analysis based on various types of Petri nets and the creation of a separate areas of software using CASE technologies (Computer-Aided Software/System Engineering), which have the ability to automate the work of software development specialists.

The third stage is characterized by the appearance of the first software products designed to solve organizational problems of enterprise management. During this period, the business environment is fundamentally changing, CASE tools are changing, which are no longer intended for automating processes, but for implementing a wide range of tasks of business analysis of enterprises’ activities. CASE models began to cover the full cycle of control system building (Figure 1.2).

A separate class of programs designed to solve management organizational issues and business modeling is being added – «BMS» (Business Modeling Software). The business model of this class includes a system of company goals, models of business processes and organizational structure of the company, as well as a reference book on the documents used. Business modeling during this period is inextricably linked with the" drawing development" of the organization, as the graphical representation allows you to make the company’s business model more transparent, accessible to the clients understanding, ready for regular analysis, management and further improvement.

The fourth stage is associated with the development of business modeling to a separate management methodology, which is called «business engineering». This methodology consists in analyzing and improving the company’s activities through the use of a process approach. A prerequisite for the success of the company is the availability of internal changes skills and their systematic application. Constant monitoring, analysis and continuous improvement of the company’s activities are among the main tasks of the new divisions.
