Navigation is at the heart of the user experience for websites, software and mobile apps.
Despite improvements in search, most users still rely on browsing as a strategy to find information or accomplish tasks.
Designing and evaluating navigation is an essential part of making a better user experience.
We’ll cover evaluating navigation in detail at the Denver UX Boot Camp. Here are 20 resources we’ll leverage.
Information Architecture
-
- Information Architecture for the World Wide Web: Now in its 3rd edition, this 500 page bible of IA covers the fundamentals, terms, techniques and details about IA as a profession.
- A glossary of IA Terms [pdf]: While the Argus website is dead, some good resources live on, including the glossary and our friend Louis Rosenfeld. Some discussions are still alive over a decade later.
- A Practical Guide to Assessing Web Site Organization: One of the few early and only sources for assessing the effectiveness of IA and navigation (see Tree Testing below).
- Information Architecture Index at University of Minnesota: A good list of blogs and resources on IA and Card Sorting.
Card Sorting
-
- 10 Things to Know about Card Sorting: If you’re new to Card Sorting, this blog is a good starting point.
- Card Sorting from the The Encyclopedia of Human-Computer Interaction.: Provides a comprehensive background to this popular method.
- Card Sorting: Designing Usable Categories: This book by Donna Spencer is a comprehensive resource for getting started conducting Card Sorting.
- Card Sorting Definitive Guide: An earlier online lite version of Donna Spencer’s take on the subject Part 1.
- Card-Based Classification Evaluation: Another take on the subject from Donna…she’s a busy gal!
- Card Sorting Software: OptimalSort and Websort.
- Analyzing Card Sorting Data with a Spreadsheet: A good source to understand the mechanics from Joe Lamantia. The link to his spreadsheet is broken, Donna Spencer found a copy and I’ve uploaded it to our server[xls].
- Sample Size for Card Sorting from Tullis & Wood [pdf]: One of the only studies examining the issues of how many users to test.
- Card Sorting Analysis Spreadsheet: Donna’s own Excel companion to the book with instructions and examples.
- Card Sorting Analysis Best Practices [pdf]: This recent article in the Journal of Usability Studies provides some updated insights.
- A Group Method of Card Sorting: This journal article discusses a method called the modified Delphi services. I’m always a bit hesitant to collect data from groups, but see if this method fits your situation.
Tree Testing
- Using Tree-Testing To Test Information Architecture: Closed Card Sorting is often recommended for evaluating navigation structures. We’ve found, like others, that a better method is conducting a Tree Test, which surprisingly has only been around for 4 years.
- Webinar on Testing Website Navigation: We walk through a case study combining Card Sorting and Tree testing using Target.com’s navigation.
- Card Sorting + Tree Testing: The Science of Great Site Navigation: A detailed discussion and Q&A around using both Card Sorting and Tree Testing.
- Tree Testing, A Quick Way to Evaluate Your IA: Probably the first description of the method of Tree Testing.
- Tree Testing Software: Optimal Workshop’s Treejack and MUIQ.
