INNOVATION AT YOUTUBE
4
o Who are the users? Create personas (user modeling)
Why do people making funny videos? (content analysis)
Why do people share videos? (social capital)
Talk to customers all the time (informal feedback)
o Automated key metrics updates
o Product direction driven by qualitative/quantitative user feedback
o Everyone feels a sense of ownership

DESIGN INSPIRATIONThink like a game designer
Unpack user behavior the way an anthropologist or sociologist studies social practices5
Formulate strategy at the systems level(e.g. metaphors, game mechanics)
Understand user’s goalsmotivationsincentives
Harness interplay between user segments

LEAN YOUTUBE
Determine what users care about => Focus => Simplify => Focus more => Simplify more
•Release minor updates every week•Release feature upgrades every month•Launch site redesign every year
6
Focus on what's workingo Throw engineers at features that
users want
o Don’t get bogged down by non-performing features(If users don’t even notice the bug, they don’t use it.)
Everyone owns the entire siteo No QA testers
o Fixing bugs in your sleep

QUANTITATIVE DESIGN
http://www.flowtown.com/blog/the-state-of-youtube8
YouTube’s rapid growth has generated a lot of data, enabling us to take a systematic and quantitative approach to design.

USER BEHAVIOR TESTING
Model user types and their behaviors
Goal and task analysis
Conduct usability and eyetracking studies
Strategic design thinking at the systems level
How to determine what users want
Triangulate by combining qualitative data from eyetracking and usability research with quantitative data from statistical log analysis and experiments

A/B testing quickly devolves into an arms race for attention on the page
Bucket testing helps reveal causality
Multivariate factor analysis is scientifichttp://en.wikipedia.org/wiki/Multivariate_testing
