The ideal system concept of G. Nadler is a method in which the ideal system is first created, from which it gradually descends down to the system that meets the limiting conditions. This concept is looking for a comprehensive improvement, here the system function is the goal, and the whole system should strive to achieve this function.

The concept of the ideal system by G. Nadler had a significant impact on the methodology of organizing research. Significant is the fact that the system according to Nadler is not the sum of the system components, because the properties of the whole do not come down to the properties of the part and each system is something specific.

The proposed method is called the "modeling" method and, in contrast to the "improvement" method proposed by the classics based on current observations and analyzes, is to leave the ideal system and then gradually approach a concept that meets the imposed limiting conditions, expressing the essence of a specific process.

In Nadler's approach, it is not important to look for specific improvements to the options, but the overall concept of the process under consideration is sought.

General characteristics of the system according to Nadler include the indication of:

  1. function
  2. inputs
  3. process
  4. ambient
  5. Equipment
  6. The size of human resources

According to the concept, such a formulation of the system makes it possible to transform input streams, such as materials, information or people, into the formulation of specific products or services. The existence of a given system is perceived as its functions, included in the category of purpose, which the specific system is to serve. In addition, as the system environment Nadler defines the total of physical factors, economic, and sociological, which together create the environment of the organizational system.

Well, the considerations are based on the analysis of the unit cost of production in the enterprise. In this particular case, the ideal system is the state of the system where the unit cost is equal to zero. This system is located at the apex of the triangle and bears the name of a theoretically perfect system. In fact, it is difficult to imagine a situation, but the sketch of such an ideal concept is to be a reference to the possibilities offered by different variants of the solution, which aim to minimize unit cost. In addition, Nadler defines in a special case an ideal system as such a system that can be eliminated without affecting the functioning of the whole.

Nadler's triangle

  • The ideal theoretical system
  • The ideal perspective system
  • The perfect system implemented technologically
  • The proposed system
  • Improved system
  • The existing system

Stages of the proceedings

  1. In the initial phase, the system function is determined
  2. Then an ideal system is introduced
  3. Information is collected
  4. Suggested variants are created
  5. The next step is choosing the recommended system
  6. Then follows:
  7. System formulation
  8. System revision
  9. System testing
  10. Installing the system
  11. System operation control

Loopback - part of the control system in which information about the result of a specific action is transferred to a given unit, giving the opportunity to analyze and correct work.

If this is not possible, a perfect perspective system is designed. It assumes ideal conditions for its functioning based on the latest achievements of science and technology.

The next stages of this method are designed to "realize" the ideal system. This is distinguished by the level of the ideal system implemented technologically, created on the basis of already implemented solutions in the organizational and technical sphere, showing high efficiency. The final stage is the transition to the proposed system. The existing system lies at the root of the triangle.

This method is widely used. Its unquestionable advantage is that it does not require significant expenditures to perform analyzes of the current state, but nevertheless it is undoubtedly a more difficult method and requires high capabilities of prognostic thinking.

In addition, as Nadler claimed, this method is much more effective, than the concept of an "improved system", which arises through diagnostic procedures, thus running "from below".
