7 chapters · 3 free, 4 paid · ~109 min total

  1. 1
    What a Product Decision Actually Is

    What separates a decision from a commitment, why "we scoped it" isn't "we validated it," and the four risks any idea has to survive.

    Free
  2. 2
    Evidence, Not Encouragement

    Customer discovery as evidence-gathering. Why compliments correlate with nothing, what revealed preference looks like on the page, and what a machine summary of an interview strips out.

    Free
  3. 3
    Reading the Numbers You're Given

    Reference classes, denominators, and retention curve shape — the specific ways product metrics mislead the person reading them.

    Free
  4. 4
    Prioritisation Under Real Constraints

    Choosing between two defensible options, naming what the chosen path costs, and surviving the choice organisationally. Runway decides which arguments are even admissible.

    Paid
  5. 5
    The Launch Call

    Shipping under incomplete data: designing tests that can fail, pre-committing to kill conditions, and telling a sample that can answer the question from one that can't.

    Paid
  6. 6
    Positioning and Pricing as Product Decisions

    Positioning extracted from customer language rather than invented, and pricing as a judgment about what you will trade — not a prediction exercise.

    Paid
  7. 7
    Product Judgment When the Draft Is Free

    What changes when every artifact arrives fluent: why format stopped signalling rigour, why "cheap to build" isn't "worth building," and how to read a document for traceability.
