WHAT IT IS:
Participants are asked to rank a set of
products or concepts on a scale from most to
least desirable to determine user preference.
WHY IS IT VALUABLE:
• Helps to prioritize concepts based on what
the user ﬁnds most valuable and appealing
• Great for understanding what really matters
to users regarding your designs
• Helps to understand what people really care
about regarding your design
WHEN TO USE IT:
When you have multiple concepts and need
to make a decision around which best suits
the users needs. Works especially well when
there are physical forms, paper prototypes,
or digital prototypes that they can customize
or adjust at will.
EXAMPLE: When developing a wristwatch for women, paper mock-ups with exact
dimensions were created so that participants could not only get a sense of look
and feel, but also discuss ﬁt when making judgements and ranking the concepts.
