Which of the following statements about Scrum Theory is true?

Comprehensive and Detailed Explanation (concise, policy-compliant):

Scrum rests on empiricism and lean thinking. Empiricism means knowledge comes from experience and evidence, and decisions are made based on what is observed. Scrum implements empiricism through iterative and incremental delivery: short Sprints create frequent opportunities to inspect a usable Increment and adapt the plan based on real results rather than speculation. Iteration reduces risk by enabling rapid learning, early validation of assumptions, and continuous refinement of the Product Backlog. Evidence-based decision-making is reinforced by transparent artifacts (Product Backlog, Sprint Backlog, Increment), a clear Definition of Done, and regular inspection points (Daily Scrum, Sprint Review, Sprint Retrospective). Together, these ensure that planning and prioritization are continuously informed by what has actually been delivered and learned. Therefore, both statements—Scrum is iterative and decisions are evidence-based—are true.
