Abstract

Best-Worst Scaling BWS is a method of multi-attribute preference measurement. Its objective is to determine the preferences with respect to certain properties and characteristics. It is a stated preference method and based on the assumption that people are able to select the best and worst or subjectively most and least important from a set of three or more elements. BWS avoids, like all discrete choice experiments, the known weaknesses of rating and ranking scales. However, BWS promises to generate additional information because participants choose two times, namely the best as well as the worst alternative. This paper describes the potentials of application, the underlying theoretical concepts, and the implementation of the three variants of BWS experiments. It also shows that at least the second variant of BWS the so-called profile case is subject to restrictive and unrealistic assumptions.
