Recruiting Test Participants for Usability Studies

Another Jakob Nielsen Alertbox is out. This time he covers the key metrics behind recruiting test participants for usability studies (i.e. what does it take to get a warm body in to take user tests, who is doing it, what are the known problems, etc.).

Gorilla Usability

"Not everyone has time to conduct a formal usability study, or the money to invest in a full blown usability initiative, and frankly, lots of times that might not be the best option anyway. Sometimes a designer or developer needs that one-on-one, maker-to-user interface. Gorilla Usability will show you some ways to get to know your users in a real world, out-from-behind-the-glass kind of way." (D. Keith Robinson, evolt.org)

Information Architecture: Blueprints for the Web

In the introduction, Christina Wodtke claims that her book on IA isn't for people doing IA for a living "most of it will probably be old hat." It might be true, that her book won't make a revolution for the IA field, but it is very enlightening to read about Wodtke's practical use of the techniques and principles of IA. And there's no armchair theory here. Everything is backed up by cases, examples, and practical advice on how to make everything work in the real world.

The book concentrates on traditional IA practices, such as:
- User research
- Organising content
- Card sorting
- Personas, scenarios and task analysis
- Site and flow diagramming
- Wireframing and storyboarding

At the end of the book, you'll also find some she-devil tricks on how to persuade you boss and co-workers to do things your way. Highly revealing - my girlfriend is never going to fool me again.

Sample usability report

At the Danish usability consultancy DialogDesign, managed and owned by Rolf Molich, you can download an example of how to put together a usability report. The sample report is based on a usability test of the E-commerce website www.TowerRecords.com.

Adventures in Low Fidelity: Designing Search for Egreetings

Cris Farnum's story of a redesign of Egreetings proves the importance of testing early prototypes, by showing how even experienced interaction designers can be wrong and how we have to accept that usability tests can fail concepts, which we believe to be superior.

The article is also an interesting case on testing paper prototypes - or "tabletops", as Farnum calls it. I especially like their use of laminated printouts of screens, which the users can write on with a thin whiteboard marker.

Survival of the fittest through iterative design

Comparing iterative design with Darwin's concept of natural selection, John S. Rhodes from WebWord.com explains why iterative design and testing are important.

Natural selection happens through the production of many offsprings, each with their unique differences. The ones that are strong and fit in a way that make them succeed in their environment, will survive. That's why many quick and dirty prototypes (offsprings) and continuous testing (selection in a natural environment) are important to a successful development workflow.

Camtasia a screen recording application

Camtasia from TechSmith is a powerful alternative to video-recording usability test sessions. Camtasia can capture all the users' actions on the screen and, at the same time, record the spoken comments of the user and the usability facilitator. The result can be saved to a standard AVI movie file and edited with the Camtasia Producer.

Guerrilla HCI

Discount usability engineering is one of Jakob Nielsen's hobbyhorses and indeed his most valuable contributions to web and software design. In his contribution to the book Cost-Justifying Usability Nielsen states that software developers rarely use the recommended usability engineering methods, because they are seen as too costly, too time consuming, and all in all intimidating in their complexity.

In the paper Nielsen shows how to conduct discount usability and give some examples of how to estimate usability ROI.

Staples.com ROI derived from iterative design

In this article CTO of staples.com tells how they learned through experience that a top-down approach to Web development is doomed to fail.

Going through an iterative process with prototyping and usability testing, a makeover of staples.com resulted in an increase of the conversion rates (the percentage of visitors who make a purchase) by 75 percent.
