DESCRIPTION
This presentation is a case study describing how we combined individual card sorts with focus groups and group card sorting to improve the content hierarchy and organization of www.libertymutual.com, the personal insurance website of Liberty Mutual, which customers can visit to get an insurance quote, service their insurance policies, or find insurance-related information. We analyzed quantitative and qualitative data from 26 participants, on which we based our recommendations for a new hierarchy and site structure. Our paper will show how the results from the individual and group sorts differed, how the individual exercise informed the group exercise, and how the group exercise informed the recommendations. We believe this combination of individual sorting, group sorting, and focus group discussion makes this methodology unique. The paper on which this presentation is based is available here: http://bit.ly/14jWa7G

Our old-style navigation was no longer useful for a major insurance company’s website
Historyo www.liberymutual.com
had moved over the years to
a large site with multiple
lines of business
Issueso Display of a total of only
nine options in the top right
corner of each page
o Lack of a traditional
navigation bar

We needed to make content discoverable and easy to find
Scopeo Create a new navigational
hierarchy to replace the current one
High-Level Objectiveso Focus on the navigation and
organization of the website
o Ensure the navigation labels are understandable
o Make the site attractive to customers

To meet the needs of the project, we needed to run a card sort, a categorization exercise where users group physical or virtual cards together
• “Card sorting is excellent for situations where you want the users’ mental model to drive the information architecture of the product.”- Courage & Baxter (2005)
• “Open sorts are used for discovery. Closed sorts are used for validation.”- Morville & Rosenfeld (2006)

We reviewed research on card sorting methodologies and then developed a new methodology
Proprietary - Trade Secret (Competitively Sensitive Information)
• Repeated card sorting“Repeated sorting of a set of items to understand underlying dimensions or characteristics of a product or service” - Curran, Rugg, Corr (2005)
• Delphi and modified Delphi card sorting“Participants build on the results from previous card sorts” - Paul (2008)
• Focus group card sorting“Participants… complete the card sort individually. Then, [you] lead a discussion with [them] regarding the… strategies they used….” - Hawley (2008)
We developed a new methodology, one that had not been done before.
Simple to run
Requires only 10-20 people
Useful for understanding emotional dimensions of a product
Not useful for grouping information into different categories
Reduces time
Requires only 8-10 people, but…
Subsequent participants are modifying a card sort others started
UX research experts recommend 15-30 participants for a card sort
Collect quantitative card sort data
Collect qualitative insights
Focus group discussion may be biased by group think
Be careful about running a card sort with only 1 group of 8-15 participants

In summary, the combination of individual card sorts, group card sorts, and focus groups was successful
Our new methodology allowed us to:o Obtain qualitative and quantitative data
o Recruit a large sample size
o Save money and time
The benefit of this unique method is that the individual card sort activity enriched the group card sort activity and focus group discussion

In conclusion, two years later, the site navigation has had a positive effect on the business
Key performance indicators and web analytics demonstrate that customers are actively using the new navigation
In multiple usability tests since the navigation update, users have commented positively on the navigation, rating it as one of the best attributes of the site
J.D. Power and Associates stated that “Liberty Mutual provide[s] menus that [allow] shoppers to easily find relevant shopping tools on any page”
