Velocity is a measure of how much work a team completes in a given sprint, typically measured in story points or other units of effort. While velocity can be useful for tracking progress and forecasting future work, it has some limitations when it comes to accurate capacity planning.
Velocity can vary from sprint to sprint due to multiple factors, such as the complexity of the tasks, interruptions, or even external influences. This variability can make it difficult to predict how much work a team can handle in future sprints, leading to inaccurate capacity planning.
