The imperfect design principle: The perfect design solution will never exist. You wonâ€™t ever have time to find a perfect design solution, but you can continue working toward one for the system lifetime. Please give your thoughts. Solution Answer:) Perfection in design is not possible. You can never simultaneously satisfy all of the possible objectives for any created thing. For example, a ballpoint pen is an excellent tool for writing, until you need to erase. Yet a pencil fails you when you need to sign a legal contract. For any product there are no mathematics, and no algorithms, for deciding which objectives to satisfy in a single design, or even for accurately defining an optimal solution within any of those objectives. While there are methods that effectively evaluate and illuminate promising directions, they are sensitive tools that work as guides, not maps. All design involves too many possible objectives and solutions for complete confidence. An optimal design, in the broadest sense, is impossible. .
