What is Opportunity Assessment?
An opportunity assessment is a short, structured evaluation of a product idea before committing to build it. It answers a fixed set of questions such as the problem being solved, who has it, market size, alternatives, why now and how success will be measured, so teams can compare opportunities objectively.

In more depth
Popularised by Marty Cagan, the opportunity assessment deliberately separates the problem from any proposed solution, forcing teams to justify why an idea is worth pursuing at all. It is intentionally lightweight, often a single page, and acts as a gate before deeper discovery or a full business case. Its value is comparative: several assessments side by side reveal which bets are strongest.
Why it matters
Teams waste enormous effort building solutions to problems that are small, already solved, or not theirs to win. An opportunity assessment makes those weaknesses visible in an hour rather than a quarter. Its "why now" and "why us" questions also guard against ideas that are reasonable but poorly timed or misaligned with the team's real strengths.
A product example
Before building an analytics dashboard, a team completes an opportunity assessment and finds the problem affects only 3% of accounts, three competitors already solve it well, and it does not move the North Star. They shelve it and redirect effort to onboarding instead.
