Paired Comparison

A technique for evaluating a small range of options by comparing them against each other

www.citoolkit.com 4

Paired Comparison

A useful tool for analyzing the relative importance of different options to determine which is the

most appropriate to select

www.citoolkit.com 5

Paired Comparison

Uses . . .

To select the alternative that will be the most effective

To choose the most compelling problem to solve

www.citoolkit.com 6

Paired Comparison

When to Use?

When alternatives are completely different

When comparing different subjective options

Where there is little objective data to base our decision on

www.citoolkit.com 7

Paired Comparison

Examples of Use

Selecting the product idea or concept design for a new product before it goes into production

www.citoolkit.com 8

Paired Comparison

Examples of Use

Deciding which skills, qualifications and experience are essential when hiring people for a new role

Paired Comparison

The Paired Comparison Matrix

The matrix will ensure that each comparison is made only once to avoid duplicating a comparison

It is also not allowed to compare an option with itself

Option A Option B Option C Option D

Option A

Option B

Option C

Option D

A vs. B

The highest ranking alternative is not necessary the most important

It provides however a basis for further thoughts and discussion


Paired Comparison

How to Implement a Paired Comparison Analysis

Identify the evaluation criteria (e.g. the most important or the easiest to implement)

Identify the alternatives to be evaluated


Paired Comparison


List all alternatives on the left hand column and on the top row of the matrix


Paired Comparison


In each blank cell, compare the option in the row with the option in the column, then write in the cell the

option that better meets the evaluation criteria


Paired Comparison


Count the number of times each option has been chosen

Rank the options based on their count

Consider the options with the highest ranking

Paired Comparison

Example – How to spend your coming summer holidays:

A: Write a book B: Take a course C: With family D: Long walks

A: Write a book B C D

B: Take a course C B

C: With family C

D: Long walks

Count 0 2 3 1

Rank 4 2 1 3


Paired Comparison

Example – How to spend your coming summer holidays:

A: Write a book B: Take a course C: With family D: Long walks

A: Write a book B,3 C,1 D,2

B: Take a course C,1 B,1

C: With family C,1

D: Long walks

Count 0 2 3 1

Weight 0 4 3 2

Score 0 8 9 2

Rank 4 2 1 3

You may give a weighted score to each comparison where: 0 means no difference, and 3 means major difference


Paired Comparison

Example – Asking a team about their biggest motivators:

A B C D E F G H I

A: Appreciation A A A A A A A A

B: Achievement C B B B G B B

C: Work condition C C C G C C

D: Power D D G D I

E: Creativity F G E I

F: Interest G F I

G: Financial benefits G G

H: Relationship I

I: Self development

Paired Comparison

Further Information

If it’s a team exercise, the selection of people should be based on their knowledge of the subject matter


Paired Comparison

Further Information

Further solutions can be developed by mixing the positive aspects of a number of solutions

Use common sense, and manually adjust the results if necessary
