The Tasks Task 1 – Order a Vanilla Frappuccino Task 2 – Order from your favorites Task 3 – Order for you and a friend Why these tasks?
The Tasks • Maximum amount of coverage. • Varying difficulty levels. • Aligned with survey and task analysis results.
Design Evolution How did we get to this point?
Survey and Task Analysis • Match between system and real world
Survey and Task Analysis • Match between system and real world • Map • Proximity is key • Favorites • People order the same things
Low Fidelity Prototype • User Control and Freedom • Error Prevention • Consistency and Standards
Low Fidelity Prototype • User Control and Freedom No way for user to change an order except press the back button.

Current User Interface What does it do? How does it work? What is it missing?
Final User Test Online Survey Lab Experiment
Online Survey - Method • Implemented Logging • Tracked time to task completion • Number of erroneous clicks
Online Survey - Results • First task average completion time was 7:10 • Second task average completion time was 0:32 • Third task average completion time was 1:35 What does this tell us?How do we fix this?
Lab Experiment - Method • Observed users as they went through tasks • Used an actual iPhone
Lab Experiment - Results • Most users had trouble with Map page • High fidelity vs. low fidelity issues What does this tell us?How do we fix this?
Final User Test • Online Survey vs. Lab Experiment • Quantitative vs. Qualitative
Summary User experience driven changes Iteratively better product Different stages yield different challenges
