Harness SEI is a tool designed to help development teams accurately measure key sprint metrics such as Developer Churn, Planned vs Delivered, and Velocity, providing insights that can enhance productivity and prevent burnout. Measuring these metrics is crucial in agile environments, where developers often face challenges like burnout caused by over-allocation of tasks, lack of clarity, technical debt, and poor sprint planning. To counter these challenges, effective sprint planning is essential, taking into account team capacity and potential roadblocks, with metrics playing a vital role in setting achievable goals and prioritizing tasks. Harness SEI facilitates accurate measurement of these metrics by linking Git and Jira data to calculate Developer Churn, providing the Commit Done Ratio to evaluate sprint commitment adherence, and offering visual reports to track velocity and other sprint trends. The tool aims to empower engineering teams by providing insights for sprint prediction and performance improvement, allowing for more efficient resource allocation and better task prioritization.
