Usability Evaluation Services

We evaluate the following four dimensions of usability:

  • The effectiveness and efficiency of a product or site in supporting users goals, purposes, and objectives.
  • The ease of learning to use a product or site for beginners.
  • The ease of use for a product or site for experienced users.
  • The extent to which users prefer a product or site over others available.

We offer the following usability evaluation services:


  • Used to determine the scope and significance of users’ needs.
  • Used to define the goals, environmental constraints, and processes necessary for a product to fulfill its intended purpose(s).
  • Done using surveys, focus groups, interviews, task analyses, and/or observation.


  • Used to review the user interface of a product or web site.
  • Prerequisites to user testing.
  • Done by trained evaluators who apply empirically derived usability heuristics (guidelines) as they “walkthrough” the product or site interface.

  • Used to determine what works and what does not for users to generate potential solutions to problems.
  • Can be done in a laboratory setting (Lab user testing) or in a real world environment (Field user testing).
