Outcome
A specific, falsifiable description of what success looks like at a hackathon. Outcomes pair with stakeholders to make a goal operational; together they are the difference between a designed event and a scheduled one.
An outcome is a specific, falsifiable description of what success looks like at a hackathon, concrete enough that participants can recognize when they have hit it and when they have not. "Help participants learn something new about AI" is not an outcome; it is a hope. "Produce a working prototype that integrates one of the sponsoring partners' APIs and demonstrates a coherent user-facing behavior in a four-minute demo" is an outcome. See the-goal.
Outcomes pair with stakeholders to make a goal operational. A goal is a stakeholder plus an outcome — a real person or institution who has named what they need, and a real description of what success looks like that is concrete enough to design against. Outcomes can be calibrated to the event's scope; what they cannot be is unfalsifiable. See stakeholder and problem-statements.
