Paired comparison is a technique which compares alternatives one to one in a tabular fashion. It is sometimes also used to compare criteria and calculate their weights. Alternatives are set-up over both table axes. When comparing one alternative with another, one can give a preference over one idea to another.
Executing the Method
List all alternatives on both axes.
Compare the alternatives one by one, note down the preference for a certain alternative and the possible strengths of this preference by a numerical value (best is a 1-5 scale).
Score Compared Alternatives
At the bottom, add up the scores for each preferred alternative. For example, idea 2 has been preferred 2 times over other alternatives, and the values for these preferences equals 4.
The idea(s) with the highest scores can be selected for further development.
