Attachment A

CDC Homepage UX: Protocol for CDC Homepage UX – After Release

Participants

• CDC is contracting with a company to recruit participants. A total of 27 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:

  • 9 Healthcare providers

  • 9 Public health professionals

  • 9 General consumers

• All of the participants will complete the testing in-person.

• Participants will conduct the usability evaluation at the test location (Northrop Grumman, 2800 Century Center, Atlanta, GA).

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:

  • 10 Smartphones

  • 3 Mini-tablets

  • 4 Large tablets

  • 10 Desktop/laptops

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 -CDChomepageUX060214 – OMB).

• Consent Form:

  • Participants will be asked to sign a consent form before testing begins (see attachment C-Consent Forms -CDChomepageUX060214 – OMB).

• Web pages will be accessed via the users’ devices by web url of the live CDC website.

• 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 -CDChomepageUX0602143 – 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 - CDChomepageUX060214).

• 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 pages), 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.
