Why a small, usable product is a better starting point than a large, unfinished one.
Start with the risk
The first question is rarely “what can we build?” It is usually “what do we need to learn before we build more?” A useful first version puts the riskiest assumption in front of real people quickly.
That means choosing one audience, one job, and one clear signal of value. The product can be narrow. The learning cannot be vague.
Make the loop short
A short loop between an idea, an interface, and a real response gives a team better information than a long planning cycle. We design the smallest complete experience, ship it, and pay attention to what happens next.
Earn the next step
Every release should earn the next release. When the first version makes the right thing obvious, the roadmap stops being a list of guesses and starts becoming a record of decisions.
