Product Owner

User Interviews

Vì sao: You can design interview rounds to test a specific assumption behind a roadmap bet, and recognize when answers only confirm what you hoped to hear.

Persona Development

Vì sao: You can decide which segment a quarter's work serves and say no to requests from segments you chose not to prioritize, citing the persona data.

User Story Writing

Vì sao: You can keep a backlog healthy across several sprints, re-slicing large epics so that each story still delivers visible value on its own.

Acceptance Criteria

Vì sao: You can catch edge cases and error states in criteria during refinement, so they do not appear as bugs after release.

RICE Framework

Vì sao: You can score ten competing requests with Reach, Impact, Confidence and Effort and explain to a disappointed requester why theirs ranked lower.

Roadmap Planning

Vì sao: You can build a roadmap around outcomes rather than a feature list, leaving room for the delivery slips and surprises that always arrive.

North Star Metrics

Vì sao: You can pick the single metric that reflects delivered user value and reject vanity numbers like sign-ups when judging whether a release worked.

Funnel Analysis

Vì sao: You can locate the step where users drop off in an onboarding or checkout flow and propose the experiment that tests the likely cause.
