During Sprint Planning, the most relevant metric to consider is Throughput (Option B), which measures the number of work items completed in a given time frame (e.g., per Sprint). By reviewing past throughput, the team can make informed decisions about how much work they are likely to complete in the upcoming Sprint, taking into account their capacity and any potential changes in team composition or external factors.
*Service Level Expectation (A) is less relevant as it is more about setting expectations with stakeholders rather than planning the Sprint.
*Work Item Aging (C) is a leading indicator metric used to track how long current work items have been in progress, which is less helpful during planning.
*Work in Progress (D) indicates the current workload but does not provide historical data useful for forecasting in Sprint Planning
