About me
• User Experience Analyst / Designer • Usability tes8ng for over 10 years • Facilitated hundreds of user tests
User-‐Centred Design
UCD is an approach to design that grounds the process in informa8on about the people who will use the product. UCD processes focus on users throughout the development cycle.
It will slow us down
• Usability tes8ng is an investment. • ROI – get back a product that sells beOer and costs less to support
• Qualita8ve usability tes8ng is s8ll gold: – "I would rather sit with one user than see data from 1000"
Steve Krug
Our product is already perfect
• You do not know which parts of your design your target users will struggle with.
• You also don’t know that you don’t know. – This behaviour is oWen referred to as “drinking your own Koolaid“.
Our website is not ready to test
• Your ideas will never be stable and complete un1l you’ve had the input from users.
Current design
Before star8ng the new design, test the old design to iden8fy the good parts that you should keep or emphasize, and the bad parts that give users trouble.
Compe8tors’ designs
Test your compeEtors' designs to get cheap data on a range of alterna8ve interfaces that have similar features to your own.
Tes8ng prototypes
Make paper or interacEve prototypes of one or more new design ideas and test them..
How many users to test?
• Quan8ta8ve studies (aiming at sta8s8cs, not insights): Test at least 20 users to get sta8s8cally significant numbers; 8ght confidence intervals require even more users.
• Card sor8ng: Test at least 15 users. • Eyetracking: Test 39 users if you want stable heatmaps.
Find users
• Get hold of some representa8ve users, such as customers for an e-‐commerce site
Recruitment Agency
Social Media
Customer Lists
Task scenarios
• Ask the users to perform representa8ve tasks with the design – Write non-‐leading tasks
Observe
• Observe what the users do, where they succeed, and where they have difficul8es with the user interface.
• Shut up and let the users do the talking. • Don’t lead the users or provide hints
In person
• In person tes8ng can be done at a usability lab, conference room or hotel.
• Pros: won’t miss subtle8es of body language and facial expression
Remote
• Using web conferencing tools such as WebEx
• Great for recrui8ng users that are located in different geographic areas or hard to find audiences
Remote unmoderated
• Without test facilitator present
• Done by par8cipant on their own computer or device
• e.g. usertes8ng.com
The “Ask”
• Tourism Bri8sh Columbia • Phased site refresh • Focus on the user experience and commit to user saEsfacEon for visitors by – improving the visual presentaEon – design and navigaEon
