ted 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.
- 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
- In the initial phase, the system function is determined
- Then an ideal system is introduced
- Information is collected
- Suggested variants are created
- The next step is choosing the recommended system
- Then follows:
- System formulation
- System revision
- System testing
- Installing the system
- System operation control
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".
