Usability Evaluation
About Usability Evaluation Consulting

Our usability consultation focuses on evaluating the products - including software - for their "ease of use" and "user friendliness".

The 3 Elements of Usability
  • Effect: Determine if a user can attain the expected result correctly.
  • Efficiency: Determine if a user can attain the expected result without having to perform unnecessary tasks.
  • Degree of Satisfaction: Determine whether the user's experience was pleasant or unpleasant.

The usability evaluation process involves asking research participants - targeted users of the products - to perform a pre-defined set of tasks, collecting their opinions focusing on the above 3 elements and providing consultations based on the research analysis.
