Up to now, technical products have often been assessed for their full sustainability spectrum only after they have been developed. In the case of revolutionary products and disruptive developments, there is no generational development, so there is no information on the sustainability of previous generations. In the absence of information on previous generations, the assessment can only be a rough guide due to a lack of information, and will become more precise as more information on the product becomes available during product development. In this way it is possible to assess the sustainability of any product, regardless of its history. In addition, the knowledge gained from the previous product can be used through appropriate documentation.
