How to Gather Raw Data on Customer Needs
    •  Surveys
       –  Good for specific questions like pricing and product features
          but less useful in opportunity identification
    •  Focus Groups with 8-10 customers
      –  Highly productive but expensive
    •  Interviews
       –  1-on-1 format
       –  Cheap, effective and fast

Interviews: Who and How Many
    •  Who to interview?
       –  All relevant stakeholders (eventual
          user but also buyer, installation,
          advisor)
       –  Do not assume customer segment
          of interest
    •  Is there a right number?
       –  Looking for qualitative information
          and not statistical inference
       –  Interview anywhere from 5 to 20
          subjects

Best Practices During Interview
    •  Forget the product concept you have in mind and focus on user
       need
    •  No leading questions
    •  Ask about current behavior rather than speculating about future
    •  Ask for specific examples rather than generalizations

Interview Content
    •  User behavioral patterns
       –  Personas: Includes some information that you associate with
          customer segments – demographics, roles – but also
          behavioral patterns
    •  Identify the steps in customer journey or experience
      –  What the customer actually does in each step
      –  Pain point & emotion in each step

Summary
  •      User research through interviews can save time & money
       •  Helping prioritize user requirements
       •  Avoid building features you think are important but not relevant to user
       •  Reduce the number of product iterations needed to arrive at product-
           market fit
