1. The traditional designing did not consider the interdependence of products. They were concerned about only
one component /product. But in the modern world, the existence of one product is dependent on another in some
way or other.
2. In the past, production was on small scale. Thus the penalty of a wrong design was tolerable. But, in the present
time, production is on large-scale basis. As a result, any penalty of a wrong design will cost great loss.
3. Requirements of the customers of todayâs world changes so frequently. Traditional design lags behind the
advanced product & process technologies available today.
4. Traditional design methods cannot cope with competitive requirements of the modern world. Due to the above
reasons modern design problem cannot be handled by traditional methods.
