CDC Flu UX: Protocol for CDC Flu Card Sort

Overview – What is a Card Sort?

Card sorting is a user-centered design method for increasing a web site’s findability. The process involves sorting a series of cards, each labeled with a piece of content or functionality, into groups that make sense to users or participants.

Participants

• CDC is using partners, such as social media to recruit participants for the card sort. A total of 90 participants will be included in the card sort. The final mix of participants will include:

  • 30 Healthcare providers

  • 30 Public health professionals

  • 30 General consumers

• All of the participants will complete the card sort remotely using their own computers accessing a web based card sorting system (Optimal Sort).

Recruitment

• Recruitment will be via

  • email (See B-RECRUITMENT-EMAIL- CDCFluCardSort060214)

  • or on the Flu Website (C-Recruitment Message on CDC Flu Website-CDCFluCardSort060214).

• The web based card sorting tool will be accessed via the users’ computer by selecting the links in the recruiting email or on the Flu Website.

Sessions

• See D-SCREENSHOTS-CDCFluCardSort060214 for screen captures of the web based card sorting tool.

• Each card sort session will last approximately 30 minutes. During the session, participants will:

  • Examine a series of 112 cards.

  • Group the cards based on whatever criteria is most meaningful to them.

  • Name the card groupings.

  • Be able to provide comments on the cards and the exercise.

• Instructions will be provided in the card sorting system.

• Multiple users can be completing the task/session at the same time.

• This is an unfacilitated card sort – there will be no interaction between the participants and the CDC team.
