Do not believe that usability testing is asking for opinions, e.g. with questionnaires, although it is sometimes done for various reasons, i.e. to obtain subjective impressions of a larger audience or also to test satisfaction. Usability testing may include several kinds of activities, but the most important is giving users tasks to do and to observer how they do.

There exist several published survey instruments and that we should describe in a specialized article. One of the most popular ones is the SUS which is short and does seem to yield reliable results acreoss sample sizes ([http://www.upassoc.org/usability_resources/conference/2004/UPA-2004-TullisStetson.pdf Tullis and Stetson], 2004).
 
The System Usability Scale (SUS) includes 10 items using a five-point response items (strongly disagree -- strongly agreee):
# I think that I would like to use this system frequently
# I found the system unnecessarily complex
# I thought the system was easy to use                     
# I think that I would need the support of a technical person to be able to use this system
# I found the various functions in this system were well integrated
# I thought there was too much inconsistency in this system
# I would imagine that most people would learn to use this system very quickly
# I found the system very cumbersome to use
# I felt very confident using the system
# I needed to learn a lot of things before I could get going with this system

Introduction

Al Badre's book is about an everlasting truth--a truth that many people, many companies, many organizations have learned the hard way. That is, when designing technological systems for people to use, one must take into account the characteristics of the users, and the nature of the task, and the knowledge, experience, biases, strengths, and weaknesses that the users bring to the task. In the case at hand, the task is using the World Wide Web.”, James D. Foley, cited by informIT, retrieved 16:51, 18 November 2010 (CET))

The essence of a web usability structure, is according to Badre (2002:chapter 2):

  • Where and under what conditions will the Web site be used?
  • For what purpose will the site be used?
  • Who will use the site (the target audience)?
  • How will the site be used?

Web usability methods

Do not believe that usability testing is asking for opinions, e.g. with questionnaires, although it is sometimes done for various reasons, i.e. to obtain subjective impressions of a larger audience or also to test satisfaction. Usability testing may include several kinds of activities, but the most important is giving users tasks to do and to observer how they do.
