A presentation to the South-East UX meet-up in Melbourne Australia. The focus was learning how to interpret the results of card sorting to create categorisation and navigation.
2. Who is using or has
used card sorts in their
work?

4. Information
architecture
definition
Information architecture (IA) is the structural design of
shared information environments; the art and science of
organizing and labelling websites, intranets, online
communities and software to support usability and findability; and
an emerging community of practice focused on bringing principles
of design, architecture and information science to the digital
landscape.

5. Card sorting
definition
Card sorting is an effective, easy-to-use method for understanding
how people think about content and categories. It helps you create
information that is easy to find and understand.*
Two types of card sorting
1. Open card sorting where the user takes the cards, sorts them
into groups that make sense to the and then gives the group a
name
2. Closed card sorting where the user takes the cards and sorts
them into pre-determined group names

6. To understand how users group categories together –
What are their mental models of the information space?
To see what concepts/categories should be placed together in a
group – What goes together?
To see what concepts/categories are placed in multiple groups –
What goes in multiple places?
To understand the language used for the group –
What are the groups called?
When should
you use open
card sorting?
7. To see if your categories make sense to the users –
Are the group names correct?
To see if you have any redundant groups –
Are there too many groups that overlap?
To see what concepts/categories should be placed together in a
group – What goes together?
To see what concepts/categories are placed in multiple groups –
What goes in multiple places?
When should
you use closed
card sorting?
8. Step 1 -
Experimental
design
Understand the problems you are trying to solve
Do people use ‘Room’ as the primary way to find homewares?
Do women group long eveningwear and summer maxi dresses
together?
Where should cables sit in the categories?
What groups do people use when they try and find Microsoft
software?
Is audience appropriate for navigation?
Identify your user group – you will be creating a list for a mailing
list
Who’s your primary audience for the site?
Male vs. female
Age
Persona type
Demographics
Use of the site
9. Step 2 – Labels
for the cards
With card sorting you can sort with images or labels.
Label choice will change the results of the card sort; people like to
put similar words together, even if the concepts are a little
different
10. Step 3 –
Analysis
What are their mental models of the information space?
See the groups created across the people
Use 3d cluster view
12. Step 3 –
Analysis
What goes together?
Let’s choose a cut-off mark on what gets automatically paired
together and should be in the same group

18. Step 3 –
Analysis
What are the categories called?
Look at the lists
Rationalise the names based on the content underneath
Remember users are not good labellers; we are. So it’s our job to ensure that
the label describes the content underneath
User labels Cards included Summary Recommended and why
