Definition No. 2 Cybernetic

Engineering Designing Process is a system transforming a design problem into a design or a class of designs. Probability of this transformation P(T) determines the nature of the process. P(T) = 1 for deterministic processes and P(T) 1 for probabilistic, or heuristic processes. 

In the case of this cybernetic definition, a design problem, or specifically problem formulation, is considered as input while the design is considered as the output of our designing system. The term transformation describes all complex design activities that occur during the entire process. In the case of routine design processes, the probability of this transformation P(T) = 1. It means that there is no doubt that a transformation will take place and a feasible design will be produced. Such situation may be called 

The cybernetic definition does not specify the nature of the transformation, and this is its huge advantage. As we will learn, there are many ways to conduct this transformation ( there are many ways to skin a cat, as Sydney Gregory, one of the leaders of the British design revolution, used to say), and they are the focus of inventive engineering.
