  • 2 INDEX 1.  USER CENTRED DESIGN PROCESS 2.  USABILITY TESTING: DIFFERENT APPROACHES 2
  • 1. USER CENTRED DESIGN PROCESS When designing, one of the primary concerns is to clearly understand who the end users will be and what their work environment is. Then, proceed on a stepbasis-process toward the creation of a prototype, anticipating the final model.

  • 2. USABILITY TESTING: DIFFERENT APPROACHES Usability tests are a set of different approaches which have the aim to discover usability issues. Common approaches: •  •  •  •  Heuristic analysis Usability test with user panel Focus group Eye tracking 6
  • 2.1 USABILITY TESTING: Heuristics Heuristic Analysis is a usability test performed at least by 2 usability expert. The test consists of a review that takes into account the usability heuristics (a list of recognized common usability issues). •  RESOURCES •  •  2 usability expert No user involved COST Low: is intended to be a “discount usability method” OUTPUT Light usability report 7
  • 2.2 USABILITY TESTING: User Tests Usability Test measure actual performance on mission-critical tasks to be completed on a website or application. The test begin with the identification of the target audience, that will consist of one or more user groups. When conducting user testing, the researcher asks participants to complete various tasks without any guidance (ex: find out how to contact technical support). The facilitator measure the time taken for each single task/user and issues encountered. The final output is a usability report that describe and prioritize all the usability issues found and suggest design action for the redesign of these functionalities. •  RESOURCES •  •  3 usability expert 15 users to discover 85% of the usability issues COST Medium OUTPUT Complete usability report 8
  • 2.3 USABILITY TESTING: Focus Groups Focus Group is a guided discussion with a panel of user to assess feelings, attitudes and thoughts on a given topic. A moderator facilitates a small group of 4 to 12 participants by demonstrating or showing them a product or concept. The results of focus groups can be used as a basis for generating hypotheses for further evaluations. •  RESOURCES •  •  2 usability expert 4-12 users COST High OUTPUT User insight report 9
  • 2.4 USABILITY TESTING: Eye Tracking Eye Tracking augments traditional usability methods, and can be used together with them. This methodology provides researchers and practitioners with objective data that the test participant cannot report and the researcher cannot observe. Unique insights about first glance, search patterns, failed search, and much more offer guidance in how to solve different usability problems.  •  RESOURCES •  •  2 usability expert 10-15 users to have a significant set of data COST High OUTPUT ET report complementary with the usability report 10
