What is usability? Why does it matter?



Usability testing refers to the evaluation of a product or service by testing it with actual users. While usability testing can take many forms, the aim is to test how well a product aligns with the intended user goals and needs.



What is usability?


  • Intuitive design: was it easy to understand?
  • Ease of learning: was it easy to navigate?
  • Efficiency of use: was it easy to use?
  • Memorability: is the user likely to remember how to use it?
  • Error frequency and severity: was an error encountered?
  • Subjective satisfaction: is the user happy?



Why does usability matter?

Design is an inherently collaborative process. Throughout a project lifecycle, team members often become fatigued, which leads to an inability to identify subtle errors in an experience and inevitably, user error. Usability testing provides team members with highly valuable, unbiased opinions that improve design quality.

Usability is a necessary condition for success. If a website is difficult to use, users leave. If users leave, businesses fail. The job of a project team is to design a product that satisfies user needs and provides them with the necessary information as quickly as possible.


Goals of usability testing

  1. Determine design inconsistencies and usability problem areas that may cause user error.
  2. Collect quantitative data on participants’ performance, including drop off rates, time to completion, load time and more.
  3. Determine user satisfaction with the product and likelihood to recommend to a friend.
  4. Establish baseline user performance and user-satisfaction levels for future usability evaluations.



Usability evaluation methods

 Remote Usability Testing

    • Utilize We can conduct a test within an hour. Test can be moderated if we feel the project requires user handholding or additional explanation.
  • In-Person Interview
    • Participants can be either clients, recruited via email, or non-clients, recruited via Twitter. During the interview, we first ask users a series of exploratory questions, followed by a series of test tasks.
  • Focus Group
  • Eye-Tracking Study
    • Eye tracking studies determine whether you are focusing a user’s attention in the right place on a webpage.
  • Heuristic Evaluation
    • In a heuristic evaluation, we review either a competitors’ site or a sub-set of our own site for accepted usability principles.
  • Card Sorting
  • Satisfaction Surveys
