Usability is the ease of use and learnability of a human-made object. (source: Wikipedia)

The Red Herring of Usability ROI

“Like all of Rosenberg’s observant myths, the misguided belief that statements like these can be made (and more importantly believed!) is the great red herring of usability ROI research. Let’s rid ourselves of these top-down, macro-level assertions and get down to the real work of analyzing specific usability interventions at the project level. Only through rigorous and in-depth analysis can larger patterns emerge and applications be developed.” (Scott Hirsch – Net Now) – courtesy of ia slash

Seven Myths of Usability ROI

“Daniel Rosenberg began his talk by confessing that he doesn’t believe in usability Return on Investment (ROI). Having spent 30 years in the field of User Experience (UE), and never having been asked to justify usability by its ROI, Rosenberg raises a question: Why are we still discussing this topic?” (BayCHI) – courtesy of nick finck

An open letter to Jakob Nielsen

“Prove to the world that you understand what it takes to provide the world with good design. Prove that you understand that good design, especially as it pertains to the field of high-technology product design, is also about nuts and bolts, honest, straight-forward usability. Prove to the designers out there you understand the principles of good design by tackling your own little spot on the World Wide Web.” (Andrei Michael HerasimchukDesign by Fire)

The Risks of Discounted Qualitative Studies

“The discerning usability analyst should employ a mix of both qualitative and quantitative methods when discovering usability problems. The risks of relying heavily on a qualitative approach can lead to a severe misdiagnosis especially when usability problems are difficult to detect. This article is a response to Nielsen’s ‘The Risk of Quantitative Studies’ and shows how the problems voters had with the ‘butterfly-ballot’ in the Florida 2000 election would not have been detected with popular discounted qualitative methods. The problems with relying on one-size-fits all usability guidelines such as ‘testing with only five users’ and the inherent bias of pay-for-hire guru’s are also discussed.” (Jeff Sauro – measuring usability)

Assessing Mobile Devices more Effectively

“Most user studies in the past have focused on the use of static devices. What are the new challenges to us, as designers and evaluators, on how to approach the design and evaluation of multimodal mobile devices and applications? In other words, function, value and meaning are relational and not absolute, as the applications and services reside on the network and not on the device. From the point of view of design and evaluation this presents new challenges. But why should we be interested?”

Don Norman on Emotion Design (IT Conversation)

“Don Norman used to be known as a critic of unusable things but now, he says, he has changed. He has transformed himself into an advocate for pleasurable, enjoyable products. Beauty is good, says Norman. Successful products should a pleasure to use, and convey a positive sense of self, of accomplishment, and pride of ownership. In this keynote address, Norman shares work from his latest book, Emotional Design: Why We Love (or Hate) Everyday Things.” (IT Conversations) – courtesy of ben hyde
