Product thinking

Goals tell the team what everyone already agreed on. Non-goals record the decisions that will otherwise vanish.

If you can read your roadmap from left to right and predict every meeting before it happens, you don't have a roadmap. You have a calendar.

A spec describes what to build. A decision describes what you considered, what you rejected, and why. One ages well. The other doesn't.

MVPs aren't defined by what's in them. They're defined by what removing one more thing would break.

If you cannot describe the user problem in five messages a real user would write back to you about, you don't have a problem statement. You have a hypothesis dressed up as one.

Every product team writes success metrics. Almost none writes the metric that would tell them to stop. That asymmetry is why dead products keep getting funded.

RICE is a calculator that produces fake precision. Most real prioritization is two-by-two and a quiet, honest conversation.
