Tradition in nature is rigid and resists to changes. It allows small changes or deviation from its original tradition. The changes have to go through close scrutiny and judgment is passed. It has to go through a strict critical analysis. After a tentative change is made, the result will be scrutinized and judged either better or worse than the original. If the judgment is not favourable it has to go through thorough validation. The community tend to remain closed physically as well as mentally. It remains close to protect themselves from outside agents (plate 3).

Such process naturally has a few weaknesses. Because of no exposure the old tradition becomes rigid and static. It becomes repetitive and hardly finds new solution. Obviously, if you consider only alternatives that do not differ much from the old one you ever invent something radically new.

Another weakness of the repetitive method is that it can effectively optimize only one thing at a time. If there are multiple solutions which diverge from the old model, and from each other, it is almost impossible to validate their qualitative ranking. It cannot think inclusive way. Successful development of natural process is thus possible only under the following conditions:
