Product Discovery
Marty Cagan · Silicon Valley Product Group Free Advanced
Cagan draws the line between discovery (figuring out what is worth building) and delivery (building it), and argues most waste comes from skipping the first. Reading this gives you a vocabulary for pausing before you build and testing whether the feature is valuable and usable at all. It is the disciplined version of your rule to write down who asked and what happens if you skip it.
- Separate deciding what to build from building it
- Most features fail on value or usability, not engineering
- Test the risky assumptions cheaply before you write the code
