Measurement Methods in the field of benchmarking

In benchmarking we often come across with parameters being difficult to measure while executing comparisons or analyzing performance, yet they have to be compared and measured so as to be able to choose the best practices. The situation is similar in the case of complex, multidimensional evaluation as well, when the relative importance and order of different dimensions, parameters to be evaluated have to be determined or when the range of similar performance indicators have to be decreased with regard to simpler comparisons. In such cases we can use the ordinal or interval scales of measurement elaborated by S.S. Stevens.
