How to manage design projects with user experience metrics

User experience metrics are measures that help you assess how your design stacks up against the needs of your customers and the needs of your business. Lab-based methods of collecting UX metrics are too slow and expensive to be part of most design projects, especially those using agile methodologies.

How to prioritise usability problems

A typical usability test may return over 100 usability issues. How can you prioritise the issues so that the development team know which ones are the most serious? By asking just 3 questions of any usability problem, we are able to classify its severity as low, medium, serious or critical.

Creating a usability dashboard

We're often told that senior managers don't have the time to read a detailed report describing the findings from a usability test.

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.

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.
