User experience vs. usability Most people use these terms interchangeable – and usability and user experience (UX) often mean the same things "[Usability refers to] the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use." - ISO 9241-11 Effectiveness: Can I reach my goals completely and in high quality? Efficiency: Can I reach my goals in a reasonable amount of time and effort? Satisfaction: Is the user happy using the product?

What do you need for a focus group? + + +

First experiment: A task-based focus group Task: Your task is to organize a business lunch. There are five people in the group. One is a vegetarian. You need to find the following information on three restaurants. Are they open during lunch hours? Do they have vegetarian meals? What kind of food do they serve, ideally, what is the link to the (preferably english) online menu? Does it have a business-like decor? What is the general price range? What is the phone number for the reservation or can I make a reservation online? Any other information that seems noteworthy Important: Please use the restaurant website to gather this information, not regular web search. For each restaurant please write down your results and the time you spent. Wein & Dine: http://www.wein-dine.de/ Laden Ein: http://www.laden-ein.com/ Lo Sfizio: http://lo-sfizio-koeln.xregional.de/

Survey Please rate each web site on a scale between 0 (not at all) and 5 (super) in these categories: Effectiveness: Can I reach my goals completely and in high quality? Efficiency: Can I reach my goals in a reasonable amount of time and effort? Satisfaction: Are you happy using the product? Which one is your favourite website? Where would you want to eat?

Discuss! What did you like? What did you not like? Did it seem professional? How did you like the design? Too many images, too little? Did the website at some point not behave the way you expected? Did you click on something although you were not sure what would happen? Were you confused at any point? Did you hit a road block in navigation and had to reset the website by using the back button or other means? How would you design such a website?

User Centered Design User-Centered Design is a principal that involves users from the beginning of the design process to the end The goal is to have both high usability and a good match to user expectations It is iterative. Each version is an improvement over the one before. Designers are not users More cycles are better sapdesignguild.org

User Centered Design (2) Research: By talking to your users, find out their needs, tasks, environment look at similar products Design: Fast Prototypes Interface first Stick to basic design rules sapdesignguild.org

User Centered Design (3) Adapt: Adapt your design to user needs and input Ideally with the user at the table Measure: Use structured usability testing You need numbers AND opinions Identify priorities and alternatives, then back to research sapdesignguild.org
