Scrum addresses complex work through learning from experience. A usable offering provides observations that can challenge assumptions and guide adaptation. An elaborate plan or senior opinion alone does not establish the customer outcome.

Review next: Distinguish a hypothesis about customers from evidence of their behavior.

The Sprint Goal is stable direction, while the exact work needed may evolve. Developers and Product Owner can clarify and renegotiate scope without endangering the Goal or lowering quality.

Review next: Separate the Sprint Goal commitment from the forecast of selected items.

Review next: Review the difference between abandoning a Product Goal and completing every item.
