Product Design and the Scientific Method

5 steps to the scientific method:

  • Hypothesis
  • Subjects
  • Experiment
  • Data
  • Conclusions

Write a testable hypothesis

Have clear, concrete assumptions

Take a skeptical view of your hypothesis–you’re looking for a market truth, not to prove out a previously held narrative of what the product should be

Choose the right subjects

Talk to the specific folks who will be the first ones to use your product–they might be a subset of your eventual audience, but start with them as your “beachhead” on the way to your destination

Run the right experiments

You need to run experiments that surface what people think of your product, not necessarily to succeed

Depending on where you are in the product design process, it might be:

  • A concept scenario
  • A diary study
  • Low fidelity prototypes
  • Full blown A/B beta testing

Analyze the data

You need to start with clear actionable data

Look for patterns that arise such as:

  • Existing features
  • Feature system preferences
  • Privacy concerns
  • Motivational triggers

Qualitative in-person testing with a few well-targeted potential audience members can help validate your evolving designs

As the design becomes more mature, switch to more quantitative methods

Draw conclusions, don’t rubber-stamp assumptions

Listen to the data-some things will plain fail, some things won’t be quite right but will lead you in a better direction, and some things will work pretty well

If everything tests well from the beginning, are your tests really robust enough to uncover the truth?
