Measuring the usability of everyday products

ISO have released a new standard for measuring the usability of every day products, like ticket machines, mobile phones and digital cameras. This standard, ISO 20282, includes test methods for quantifying the usability of consumer products to ensure they meet a pre-defined quality level. This development is exciting because the standard's focus on usability measurement reflects a sea change in the evolving practice of usability. In the old world, usability specialists just found usability problems with a design. In the new world, usability specialists also answer the question: "How usable is this design?"

Data collection for usability research

How should you go about collecting data in usability tests? This article examines the data collection process in usability studies and describes some popular data logging solutions. Since most of these tools are expensive, we show you how you can use Microsoft Excel with Visual Basic macros to collect the data.

Measuring satisfaction: Beyond the usability questionnaire

Most usability tests culminate with a short questionnaire that asks the participant to rate, usually on a 5- or 7-point scale, various characteristics of the system. Experience shows that participants are reluctant to be critical of a system, no matter how difficult they found the tasks. This article describes a guided interview technique that overcomes this problem based on a word list of over 100 adjectives. We also include a spreadsheet to generate and randomise the word list.

Measuring usability with the Common Industry Format (CIF)

Are you a CIO, purchasing officer, or IT manager, about to invest in productivity software for your company? If you are, here's a question you should ask your supplier before you sign on the dotted line: "Just how usable is this product?" Astonishingly, most companies won't be able to answer, and those that try will answer the question only vaguely. But now help is at hand. It's called CIF. And it's about to change the game.

This how-to article shows you how to exploit the full functionality of Morae when carrying out a paper prototype test.

Why you shouldn't ask “Why?” in a usability test

This year marks an important anniversary for people who moderate usability tests. In a classic study carried out exactly 30 years ago, psychologists showed that people are very poor at explaining the reasons behind their choices. This is why usability tests focus on what people do, not on what people say. So why do so many usability test moderators continue to ask participants, "Why"?

Standards update: Usability test reporting

It's a truism that even a bad usability test will help improve your software. But the findings from different usability tests are notoriously difficult to compare. This makes it difficult to track usability improvements or to see how you compare against an earlier product. An emerging international standard looks set to solve this problem.

Usability test data

People often throw around the terms "objective" and "subjective" when talking about the results of a usability test. These terms are frequently equated with the statistical terms "quantitative" and "qualitative". The analogy is false, and this misunderstanding can have consequences for the interpretations and conclusions of usability tests.

Checkpoints for reviewing usability test reports

Usability practitioners are called on, not only to conduct many research studies during their careers, but also to read, review, and advise on usability studies that have been conducted and reported by others. The ability to critically review the research of others, and to help stakeholders weigh up the merits or shortcomings of research data and conclusions, is an extremely valuable skill. These checkpoints will help you ensure your review covers the key issues.

Discount usability: time to push back the pendulum?

Discount usability techniques are a great way to eradicate usability problems. But they can never answer the question, "How usable is this system?" We blow the dust off some techniques commonly used in the early days of usability testing to see if they can provide an answer.

The A-Z of Usability

Rather than create yet another definition of usability, we decided to take a different approach and work through the alphabet, picking one word for each letter to capture the flavour of the field. So we proudly present the A-Z of usability — or usability in 26 words.
