Goal-adverse values lead to failure. This holds true the more important factors are where the variant differs from ideal. But it is never known with certainty what the ideal values are. This only
can be derived from comparisons of many successful variants.
The FACTORFINDER-Procedure aims at finding relevance values by comparing examples and this despite missing knowledge on the ideal values. The procedure builds on the assumption, that a successful variant with non-ideal values in important factors must show ideal factors in all the rest of the factors. Otherwise, this variant would fail. Furthermore, if a successful variant consists of non-ideal values, all these non-ideal factors are less than critically important since the variant is acceptable.
