  1. A DESIGN SPRINT IS A FLEXIBLE TIME-BOXED PROBLEM SOLVING FRAMEWORK

    THAT INCREASES THE CHANCES OF MAKING SOMETHING PEOPLE WANT What Is A Design Sprint?
  2. IDEO XPLANE CHESKIN BITOMI COOPER FROG FITCH MELVILLE IDEO ED

    Discovery Interpretation Ideation Experimentation Evolution STANFORD Empathize Define Ideate Prototype Test Prepare Form Harden Fire & Glaze
  3. Define Understand Build Test Ideate Understand Diverge Prototype Validate Decide

    2013 Unpack Sketch Prototype Test Decide 2015 Understand Diverge Build Test Converge Empathize Define Prototype Test Ideate Map Sketch Build Test Decide 2016 Design Sprint Processes
  4. ANYTIME CUSTOMER VALIDATION OF A NEW DESIGN IS REQUIRED WHEN

    YOU DON’T HAVE DATA WHEN THERE ARE ASSUMPTIONS WHEN YOU ENTER NEW MARKETS WHEN YOU DESIGN SOMETHING NEW When Is A Design Sprint Used
  5. Why is the headline always something like ‘Millennials aren’t buying

    fabric softener’ rather than ‘P&G fails to adapt to new market’? Alyssa Smith MILLENNIAL CONSUMER
  6. GOAL: FOSTER CLIENT LOYALTY DESIGN SPRINT: LOYALTY IDEATION TESTED MULTIPLE
