Key ideas in Product Strategy: Deciding What to Build
- A roadmap that says yes to every good idea spreads team focus too thin across unrelated goals
- Strategy requires defining clear boundaries on what the product will deliberately not pursue
- A collection of valuable features does not automatically equal a coherent, focused product direction
- True strategic trade-offs require accepting an intentional weakness to protect a primary strength
- Trying to satisfy every user preference dilutes the product's main competitive edge
- Being unbeatable at one dimension means deliberately giving up being good at other dimensions
- Shipping faster is operational efficiency, which competitors can match and copy
- Strategy dictates which direction the product heads, not just how quickly it delivers code
- Speeding up execution without strategic differentiation just builds the wrong things faster
- A valid strategy statement has an opposite that a sensible competitor could choose to adopt
- Statements like 'build the highest-quality, easiest-to-use tool' are platitudes because no competitor would intentionally choose poor quality or confusing UX
- Non-goals explicitly define relevant features that the team agrees NOT to build for this release
- Defining non-goals upfront stops engineers and designers from debating and architecting edge cases they don't yet need
- Clear non-goals protect scope by pre-answering common feature requests before development starts
- Broad audiences have scattered, conflicting needs that make product positioning vague
- A specific underserved group has shared, intense complaints you can solve completely
