Summary of Notes
• Adding tradeoffs / detail to requirements (when does mom need to know?)
• Change
• New info
• Have an evolvable plan
• If X happens within time Y, we can do Z1, Z2, …
• Explore possible steps
• Refine choices: trade how much food?
• Prioritize
• Meet immediate & pressing needs
• Detail plan
• Cover self as well as others
• Execute?
• Evaluate / correct?
• Develop more resources
• Think of unusual resources (e.g., train station)
Quality of Observations
• Self observation & notes
• How many others did you observe?
• What questions did you have in mind when you observed?
Breakdowns & Opportunities
• Where are the pain points? Badness of experience?
• Breakdowns
• Unmet needs
• Wasted time
• Innovations & work arounds

• Come up with 3-5
Ideas for user needs
• What needs would you meet in an app?
• List as many as you can (10? 15?)
Inspirations
• See people doing something, have an “aha!” moment
• X would be a really great new product / service /app
• This is how I would go about making X happen
• I watched people doing Y and it made me think of X
For next week (homework)
• Develop detailed scenario / storyboard for your app
• See Assignment 3 under Klemmer’s Stanford course for a guide
Keep in mind the real-life constraints
