CDC Homepage UX: Protocol for CDC Homepage UX
Dec. 10, 2013

Participants

• CDC is contracting with a company to recruit participants. A total of 24 participants will be included in the usability testing (30 participants will be recruited to account for “no-shows”). The final mix of participants will include:

  • 8 Healthcare providers

  • 8 Public health professionals

  • 8 General consumers

• 17 of the participants will complete the testing in-person and 7 will complete the testing remotely.

In-person/Remote

• In-person participants will conduct the usability evaluation at the test location (CDC offices).

• Remote participants will utilize screen sharing software and a conference line so the facilitator is able to view the screen of their device (desktop/laptop) as well as talk to them via the conference line. On the day of testing, Facilitator will start the screen sharing software and will give control to participant to share his/her screen. Participant agrees to shares screen.

Devices

• During testing, the participants will use a mix of their own devices so that the website can be tested in multiple views. The types of devices to be included is as follows:

  • 7 Smartphones

  • 5 Mini-tablets

  • 5 Large tablets

  • 7 Desktop/laptops (for remote participants)

Sessions

• Each session will last approximately 60 minutes. During the session, participants will:

  • Provide their initial impressions of web prototypes

  • Perform a series of tasks using the web prototypes.

  • Provide reactions to the proposed designs and the website improvements.

• Facilitators will verbally provide instructions to participants (see attachment B - Instructions -CDChomepageUX121013 – OMB).

• Consent Form:

  • In-person participants will be asked to sign a consent form before testing begins (see attachment C-Consent Forms -CDChomepageUX121013 – OMB). Remote participants will be asked to sign and digitally return consent form before the session begins.

• Web prototypes will be accessed via the users’ devices by web url. The web prototypes are CDC urls (web pages) to be evaluated.

• Scenarios to complete and questions will be provided to the users verbally by the facilitator (not via the computer). Scenarios may be presented to users in random order in order to avoid learning biases. See attachment D-Scenarios -CDChomepageUX121013 – OMB for facilitator copy of the scenarios/questions to be provided verbally. The participant will have a list of scenarios on paper to refer to if they choose (see E-Participant Scenario List - CDChomepageUX121013).

• As each scenario is provided verbally to the participant, the participant will try to complete the scenario by clicking on the web prototype on their device.

• Facilitator will

• monitor the participant’s actions (on web prototype), comments, frustrations, etc.,

• monitor time so that there is time at the end for final questions,

• elicit overall reactions to web prototypes and answers to specific end-of-session questions and thank the participant.
