Improving the user experience means starting with the right measure or measures to manage. Here are 10 of the more common ones I've written about: SUPR-Q: The Standardized Universal Percentile Rank-Questionnaire is a 13 item instrument for measuring website usability, credibility/trust, loyalty and appearance.

Completion rates are the gateway metric. If users can't complete tasks on a website, not much else matters. The only thing worse than users failing a task is users failing a task and thinking they've completed it successfully. This is a disaster. The term was made popular by Gerry McGovern and disasters are anathema to websites and software. Measuring Disasters Have you ever bought the

UX professional salaries have increased 7% from 2009 to 2011. During that same period the profession has also grown.

In 2011 the question posed was "How many user experience-related staff work in your entire

Marketing and UX both play important roles in making products successful. They often compete for the same limited budget and can be at odds on product direction. I crunch numbers for both Marketing and UX groups and can't help but notice how much both disciplines have in common. They are an unlikely couple. Here are nine things they have in common. 1.

Recently Nielsen conducted a study on the reading speeds between the printed book, Kindle and iPad. From 24 users the study concluded that the iPad took about 6.2% longer (p =.06) and Kindle about 10% longer (p <.01) to read than the same story on a printed book. From this data Nielsen concluded "Books Faster than Tablets" and while tablets have improved dramatically over the

It's been ten years since the dot-com flame-out began. In those ten years we've seen the rise of User Experience. User Experience seems to have a lot of buzz and gets attached to all sorts of activities that have little to do with the user or the experience.

Does a PhD pay off financially? I recently helped conduct the statistical analysis of the UPA 2009 salary survey[pdf], and used this opportunity to look into the data to see if I could calculate how much a PhD affects salaries in this profession.  The dataset contains salary information for a wide range of jobs in the profession—usability engineers, designers, managers and information architects.
