Usability Test

Introduction

We start the usability test with an expert review (including client interview and usage scenario definition) as a result of which usability bottlenecks and points of interest are determined. Next, ten or more users are invited to perform the defined usage scenarios. During scenario performance the users' performance and behaviour is monitored and measured by one or two of our usability experts. Subjective measures are assessed by means of questionnaires. This type of test is the most extensive form of usability testing which enables an in-depth analysis of software usage (user behaviour and experience) and determination of usability in terms of effectiveness, efficiency, satisfaction and learnability.

Costs

A typical usability test will take 4 to 8 weeks and is performed by at least two of our usability-experts. Costs are usually between EUR 30K and EUR 50K, depending on the size of the application or website, the experimental design, the availability and number of subjects and the required detail of the output.
