Mission Statements
Our most important use cases

• Customer looking for a price!• Customer looking for dealers who sell our
products
Paper prototyping & paper testing
• Print out your web design• Ask them to fulfill serveral tasks– Make a circle around the logo– Where would you click for contact information– Make a circle around the search engine
• Talk with your users!– What is your impression of the site?– What do you think is the site about?– What would you do if…?
Think aloud method
• Set up a scenario• Per test user exactly one use case• Per use case 4 to 5 test users• Simply document what the users do and say• Use tools for screen capture• Talk with the user afterwards• Discuss findings in the project group
What we did to get people involved
• Guidelines we developed: – How-to write web texts– How-to make quick and dirty usability tests– How-to optimize the navigation
• Get whole team to watch videos from usability testing
• Inform management of results
Our top findings

quotation system• Consumer couldn‘t find products on our corporate
website (Usability test)– New link strategy between our corporate website and
country websites• It took to long that users found our contact
information (Usability test)– Wrong naming
