A portfolio has three candidates: a high-value use case with available approved data, a flashy demonstration without an owner, and a low-value task requiring a major data program. Which should normally lead the first delivery wave?

1. The unowned demonstration because presentation impact is the only criterion.
2. The high-value, feasible use case with approved data and accountable ownership.
3. All three equally without considering constraints.
4. The lowest-value task solely because its data program is expensive.
