Here's a slanty-design answer, since other answers have covered "right" ways to do it. If you must hide the phone number, instead of making it a purely punitive task to show it, make it just seem like an unintended extra step. Obfuscating the phone number and only revealing it when the user clicks on it is like dangling information in front of people. They ...

There is usually some tradeoff between UX and administrative information. In my somewhat biased opinion UX should be the priority. Ask yourself the question: "Would I rather have fewer less happy customers, but know more about them, or more happier customers and know less about them?" That is the essence of what you're doing, and unless there is some ...

In addition to the HEART metrics (Happiness, Engagement, Adoption, Retention, Task Success) we also measure 1) new user adoption by whether or not training costs decreased and 2) existing user adoption by whether help calls decreased. I'll try to answer your follow up question and to do so you must first understand the personality of the user's you're ...

If it's a desktop application, then you'll be able to pick up the units settings from the OS. These are set at install time, so require no user interaction, which is perfect. If it's a webapp you can get the language information from the language-accept header which will generally tell you the country as well as the language. For example language-accept ...

I was just reading an article on Coding Horror that draws parallels between GroundHog Day and A/B Testing. But, I think the movie tells you a lot more about Learnability than A/B testing. In the movie, Bill Murray, lives the same day over and over again for a very long (debatable) time. He wakes up in the morning living the same day over and over again, with ...

Don't show the numbers to the test takers, it will only confuse them. But you may want to use them internally. Balanced keying (using an approximately equal amount of positively and negatively keyed items) is often used in psychometry and is considered good practice. It allows you to approach a topic from different perspectives. Some sample items ...

Comparing usability between systems (or within different versions of the same system) is explicitly the point of the System Usability Scale. The point of SUS scores is that they're fairly vague, and since you're supposed to be comparing generally similar systems (why would you be comparing dissimilar systems?), they can be a quick and dirty way to get some ...

Length of stay as a stand alone metric is a bit of a vanity metric. How long someone is on a page doesn't really tell you much, generally. It is what action they took before and after the page view that would give you some real insight. For example, if after going to a category landing page a majority of your users bounce within 15-20 seconds, then it ...

I looked for one myself some time ago and couldn't find anything. The thing is that the SUS was released as a free “quick and dirty” scale and nobody “owns” it in the way the Human Factors Research Group at UCC controls the SUMI. Perhaps more importantly, there are now quite some published data on the English-language version of the SUS and its ...

Two things. First, you need to decide what you're doing before deciding which type of card sort. Are you validating an IA you've designed or letting patterns emerge without an existing IA. You'll need a closed card sort for the first and an open card sort for the second. Second, my favourite tool is OptimalSort. They actually have a bunch of online ...

Another tool you could consider is websort. It's quite easy to set up and gives nice visuals of the results. If desired you can add images to the cards, which can be useful for example when sorting webshop items. It gets a bit cluttered if you need to sort a large number of cards (>30) though. Also consider the real-world alternative with post-its if you ...

Learning = understanding + remembering IMO when added to the usability definition, the learnability facet refers to how recurring users can get back to the UI and already know how to use it because they learned about it in the previous sessions. If so, then this could be measured by comparing performances of a first session against a later one. If you ...

The effort you spend in coding, analyzing, prepare and filter the analytics data is huge. Why not just do an usability test for both designs with persons you can ask, instead of do unknown magic with analytic numbers. Give them a predefined task first time and meet them again a week later with same task. It costs you 2x1day for 6 people (80% error ...

It depends. A Good, Short Stay is when the user gets their information immediately, like asking Google a calculator / dictionary question that the search page answers immediately. A Bad, Short Stay is when the user gets overwhelmed by the site, decides it's not the right site, or they notice "malware-y" behavior like instant redirects, porn pop-ups, or ...

Well if you display it as mV, at least you don't have to worry about whether to use a comma or a point as your decimal mark! (Since I would have read that as 3 thousand volts!) However, apart from the internationalization aspect, the question arises - At what point do you determine that V becomes more appropriate than mV? For example why is 3789 mV ok and ...

The preferable way to display this is a fraction. It is a very common form of display that anyone in the United States who has held a tape measure will find (be it for fabric or construction). (from http://www.wwgoa.com/my-three-favorite-measuring-tools/ ) If one is to use a decimal rather than a fraction, it should be shown to to the two or three ...

I would use a set of questions on a scale: for example, "I only use a computer when I really have to" or " I use a computer for a number of tasks, but sometimes have to get help" right up to "I am a computer expert who works in computer problem solving" The important thing is to define the limits of the scale, and make every entry positive, which is a ...

I want to start with just saying that if you only measure the performance based on time on task etc you will not get the correct picture of how sucessfull the web site is. The most important thing is to look at how the visitor perceive the usefulness. People could have a pretty lousy success rate but still feel that the web site is helping them better than ...

Building on Marielle's excellent answer, I just want to add that you should be careful when assigning numerical values to a scale that is still basically qualitative in nature. That doesn't mean you shouldn't, you should just be careful how you use those values. When you have a value, you can calculate things like percent changes between two measurement ...

Sadly, not really. What you're asking for is an absolute unit of measure, which should make points, picas, millimetres, inches, etc. all valid option (for any defined definition of "point", at least—it used to mean 72.27 PPI, but was standardised to 72 PPI for PostScript). When the Macintosh was first released, its physical screen density was, it just so ...

There are several methods of measurement and I'm assuming your goal is to measure usability. The first method would be doing usability tests. Set the major goals you want your users to achieve and let them accomplish them in all the UIs you have. See which UI facilitates reaching those goals better. I suggest you read Jakob Nilsen's: Why You Only Need to ...

These tools all suggest that the card sort will be a digital one, if you are going to be doing offline card sorting there are lots of great excel files explained by Donna Spencer in her book Card Sorting http://rosenfeldmedia.com/books/cardsorting/. I'd always recommend learning excel for number crunching as whatever tool you use you are likely to run into ...

I just looked at http://isitjustme.de/2012/01/crowdsourcing-the-translation-of-sus/ users user13154 recommandation. It seems that the effort was picked up by SAP and there is a professionally translated and verifyied version at http://www.sapdesignguild.org/resources/sus.asp

You can find the version that we use here: http://minds.coremedia.com/2013/09/18/sus-scale-an-improved-german-translation-questionnaire/ In the development of the German version of the scale, we analyzed and included the other sources mentioned in earlier posts and eliminated a problem with one item. The scale was used with > 80 participants, without any ...

I'm looking at your problem in a slightly different perspective. Please correct me if I'm wrong but I believe that you want to know if you should give any special importance to data collected from frequent visitors vs infrequent visitors. A rating of 5 out of 5 by a frequent user may make your site great for frequent users but it may not make it great for ...


2

That's certainly one dimension to look at, and it would be a good proxy for learnability in some situations. I think you'll have problems using it as a direct metric to compare sites however. As a separate point, some companies get hung up on the "standard" definition of usability - and start looking for metrics to track learnability, etc. over time. I ...

I recently read an interview with Jonathan Ive (Head Apple designer) and a few paragraphs struck me as cutting to the heart of this issue: Q: Do consumers really care about good design? A: One of the things we’ve really learnt over the last 20 years is that while people would often struggle to articulate why they like something - as consumers we ...

Self reporting doesn't work for something like this. Instead ask them a few proxy questions such as: How often do you use a computer? How often do you use a computer in your free time? I'm sure you can think of some others, but the general idea is to ask about something else that correlates to proficiency but is more objective.

One thing that is often stressed in education is that it's almost impossible to measure the effiencey in changes on how we teach a topic. There are to many factors that influences learning. And I think the warning is applicable here as well. Learning a new interface and learning algebra are very different things but share the same problem when we try to ...

Personally, I would prefer to show the phone number and try my best to track interactions with it via various analytics methods: Add a hover event on the parent element that fires off once per page load when the user hovers on the parent element containing the phone number. This requires a custom event to be built in your analytics software, such as Google ...
