Paired Comparison Analysis
1. Definition of paired comparison analysis
• Paired comparison analysis is a good way of weighing up the relative importance of options.
• A range of plausible options is listed. Each option is compared against each of the other options. The results are tallied and the option with the highest score is the preferred option.
2. Advantages and disadvantages of paired comparison analysis
• It is useful where priorities are not clear.
• It is particularly useful where you do not have objective data to base this on.
• It helps you to set priorities where there are conflicting demands on your resources.
• This makes it easy to choose the most important problem to solve, or select the solution that will give you the greatest advantage.
3. Steps to conduct paired comparison analysis
• List the options you will compare (elements as A, B, C, D, E for example).
• Create a table 6 rows and 7 column.
• Write down option to column and row; A to row second, cell first from left and A to row first, cell second from left; B to row third, cell first from left and B to row first, cell third from left etc; column seventh is total point.
• Identify importance from 0 (no difference) to 3 (major difference).
• Compare element “A” to B, C, D, E and place “point” at each cell.
• Finally, consolidate the results by adding up the total of all the values for each of the options. You may want to convert these values into a percentage of the total score.
4. Paired comparison in performance appraisal
