What Does It Mean?

• The Hypothesis Onion – Until we connect to our customer response, it’s all just

(hopefully) educated guesses

• Iterate Quickly – Long cycles mean high investment to find out if we’re

wrong

• Flip the Process – Bring verification to the front and recast it as

experimental hypothesis

• Empiricism Throughout – Formulate and test your hypotheses rigorously

What Does It Mean For Testers?

• Learning from history: Lean Manufacturing

• A new career path

• It’s more than just the software

• It’s the entire business
