Inadequency of evolutionary Method in Modern Design Situation-

The traditional method of designing by evolution and slow change through trial-error are no longer adequate in the modern industrial world. Perhaps the most visible sign of the need for newer and better methods of designing is the experience of the massive unsolved problems that afflict modern society. In industrially advanced as well as non-so-advanced countries, the magnitude of such problems is truly frightening. If the world has to be fed and the standard of living of a vast majority of its population has to be raised above the bare substance level at which it is at present, we need a design revolution. Even the well to do countries are suffering under the burden of the problems created by the very industrial activity which is responsible for their wealth.

Design by Evolution-

One characteristic feature of this process of design by evolution was that the designers worked largely by themselves, and communicated their ideas to others only through their work. Pieces of design onformation were stored in memory, learnt and passed down during the long periods of apprenticeshop of the master craftsmen. The overall shape of the product and the process of achiving it were passed on to the future generations of artisans, but the reasons for the same were lost in the absence of any tradition of codifying the design features.
