The steps of a ruggedness test

A ruggedness test requires an experimental design approach. It consists of the following steps  

Selection and identification of the operational or environmental factors to be investigated  

Selection of levels for the factors to be examined. In a ruggedness test 2 or 3 levels for each factor are normally considered. The ruggedness for the factors in the intervals between the factor levels is then investigated  

Carrying out the experiments described in the design. This is the experimental part of the ruggedness test  

Computation of the effect of the factors on the response(s) of the method, to derive which factors might have experimentally relevant effects
