There is hardly anything around us that hasn't been constructed. The chair we are sitting on, the screen on which this text is being read - or the hand in which it lies. They were all constructed for the same purpose: to be used. Some serve this purpose excellently, others less well, and some not at all. But what makes the difference? Is it the utility of the product, its quality, its appearance or its handling?
The answer is not always obvious because there are usually several factors involved – not to mention subjective aspects. Often, however, the subjective factors make the decisive point, because the assessment of whether something is good or bad is in the eye of the beholder. The consumer, user or customer personally forms their own opinion about whether the product suits them or not.
So the real question is: what properties of a product produce the decisive effect during judgment?
In reality, it doesn't matter what property it is because it is shaped either in the manufacturing process or during its design. It is difficult to say which of the two has the greater influence. Even the most perfect production cannot make up for errors in product design and vice versa, faulty production will never lead to a perfect product. The truth is that the manufacturing process must also be designed. After all, design, or rather the design process, remains as the only really decisive factor.
