Metrics can be used to better plan and those used for each planning horizon are perfectly aligned with their purpose—one for execution, and one for forecasting.
These metrics are used by individual teams, typically in a Scrum environment, to gauge their current performance and plan the immediate two to four weeks of work. They focus on work completed and team predictability.
These metrics are used by program managers and executives to track strategic progress across multiple teams and to forecast major deliverables over quarters or years. They focus on strategic alignment and release predictability.
In essence, Sprint Metrics (like Velocity) provide the proven historical rate of delivery, which is the critical input that feeds into the Advanced Roadmaps Metrics (like Capacity and Release Burndown) to create a data-driven, realistic long-term strategic forecast.
