Paired Comparisons

What is Paired Comparisons?

Paired Comparisons is a decision technique where every option is compared to every other option one pair at a time. For each pair, the team votes on which is better. The option that wins the most comparisons ranks highest. It is especially useful when criteria are hard to quantify or when the team struggles with the abstraction of scoring matrices.

When to Use It

• •When criteria-based scoring feels too abstract for the team
• •When options are qualitatively different and hard to score on a common scale
• •When the team needs a quick ranking of 4-8 options
• •As a validation check on criteria matrix results

How to Use It: Step by Step

1. 1

   List all options

   Write each solution or option on a card or row. Label them A, B, C, etc.

2. 2

   Compare each pair

   For every possible pair (A vs B, A vs C, B vs C, etc.), ask: "Which is better overall?" Record the winner.

3. 3

   Tally wins

   Count how many times each option won. The option with the most wins ranks first.

4. 4

   Review the ranking

   Does the ranking make intuitive sense? If not, revisit the comparisons where the team was most divided.

Pro Tips

• ✓With N options, you need N*(N-1)/2 comparisons — keep options to 8 or fewer to stay practical
• ✓Use secret ballot for each comparison if power dynamics are a concern
• ✓If there is a tie, use a tiebreaker criterion the team agrees on in advance

Facilitation Guide

Run a 2-hour selection and planning workshop. Review the shortlisted ideas from Step 3 (10 min). Define evaluation criteria as a team and assign weights by consensus (20 min). Score each solution independently, then discuss and reconcile scores (30 min). Select the winning solution and document the rationale (10 min). Build the RACI chart — list tasks, assign R/A/C/I for each team member (20 min). Draft the implementation timeline with milestones, owners, and dates (25 min). Close with a risk brainstorm and mitigation plan (15 min).
