  • What is Usability Testing?
    Observing an end-user perform scenario-based tasks
    Participants will typically be asked to follow the “think-aloud protocol” which asks the participant to say whatever they are looking at, thinking, doing, and feeling at each moment.
    Typically performed in a usability testing lab setting (controlled environment), however it can be performed remotely.

  • What is Usability Testing?
    The key stakeholders of an application/system to observe actual end-users interacting with the application/system (can be a prototype, developmental iteration, production-ready, and/or pre-existing).
    Data collected can include:
    subjective-anecdotal feedback
    success rates
    task times
    error rates
    subjective-satisfaction ratings
  • When can it be most beneficial?
    Early stages of project requirements gathering;
    Early stages of project design;
    Throughout development;
    Existing applications / systems
  • Who can be involved?
    End-users
    Key Stakeholders
    Project Managers / Consultants
    Technical Leads
    Developers
    UI Engineer
  • Who can it be most beneficial to?
    End-users
    Key Stakeholders
    Project Managers / Consultants
    Technical Leads
    Developers
  • How is it accomplished?
    Meeting to determine:
    application / system to test
    specific tasks to test
    who the target end-users are to test
    timeline for conducting usability testing (pre & post)
    Draft scenario-based tasks for testing
    Recruit & schedule testing participants
    Run through of scenarios with actual testing equipment/systems/applications
  • How is it accomplished?
    Invite observers for testing (stakeholders, PM, TL, Dev Team, etc.)
    Conduct Usability Testing with observers
    Testing debrief with all observers
    Analysis & report deliverable, if needed
  • Format - Overall
    Planning & Preparation
    Testing
    Debrief & Data Analysis
  • Format – Testing with 3 participants
    Morning Set-up
    8:00 – 8:30 am
    Participant 1
    8:30 – 9:30 am
    Break (for Observers)
    9:30 – 9:45 am
    Participant 2
    9:45 – 10:45 am
    Break (for Observers)
    10:45 – 11:00 am
    Participant 3
    11:00 – 12:00 pm
    Observer Debrief Session (Working Lunch)
    12:00 – 1:00 pm
  • Cost Factors
    Potential Budget:
    High
    Depends on the number of individuals involved and the number of observers
