Everybody interested in the importance of factors is encouraged to use the FACTORFINDER-Software. As well, everybody who seeks preferable variants among a bundle of evenly acceptable alternatives should consider using the FACTORFINDER-Software. This software identifies variants that offer the advantage of tolerating unexpected deteriorations to the largest extend.
The FACTORFINDER-Software alarms if there is no such robust variant or if there is an alternative among those recorded that differs drasticly from all other variants.
Analysts should refrain from using the FACTORFINDER-Procedure, if they wish to sort all known alternatives and put them into a ranking. To assign cooefficients that represent the attractiveness to each alternative, the planner must have an explicit causal model of all the dependencies. On the other hand, the FACTORFINDER-Software helps in an earlier stage of analysis to develop such a model. Moreover, if it is possible to sort each alternative one by one in an accending order, the crucial criterion that differenciates all the variants in just two groups (acceptable ones and inacceptable ones) is missing.
