The scrum master for a large project must provide an estimate of what can be delivered in six months. What should the scrum master do?
The correct answer is D. Use the team's historical velocity to calculate a range of features that can be delivered. Long-range estimates in agile are best expressed as a range based on empirical data - specifically the team's historical velocity. By calculating velocity over past iterations and projecting it forward, the scrum master can provide a realistic, defensible range of features…

Explanation
Long-range estimates in agile are best expressed as a range based on empirical data - specifically the team's historical velocity. By calculating velocity over past iterations and projecting it forward, the scrum master can provide a realistic, defensible range of features rather than a false-precision commitment. Option A (commit to specific features) creates a fixed-scope promise that ignores agile's embrace of change and uncertainty. Option B (wait until after planning) is unhelpful when a high-level forecast is legitimately needed by stakeholders. Option C (estimate in story points to commit to a specific set) is too rigid - velocity-based ranges account for variability and are more honest about uncertainty.
