Unlocking Efficiency: Exploring Churn Rate with Harness Software Engineering Insights (SEI)

Table of Contents

Key takeaway


Improving the effectiveness and productivity of developers is crucial for the success of an engineering team. To achieve this, the team should adopt a metric-driven approach to identify the root causes that scales down the team's productivity. Out of the many metrics that engineering leaders can use to understand an engineering team's productivity is Churn Rate. In this article, you'll learn how high churn rates can impact the team and how Harness SEI can help lower churn rates in your organization.

What is Churn Rate?

In the context of software development, churn rate refers to the amount of work that is added or removed from a sprint backlog during a sprint. It measures the scope change and provides insights into the volatility of the sprint backlog.

  • A high churn rate indicates a lot of changes in the sprint backlog, which may result in delays in completing the sprint, and may also indicate that the requirements are not well-defined. 
  • A low churn rate suggests that the sprint backlog is stable and the requirements are well-defined.

Why Churn Rate Matters?

Unveiling Sprint Volatility:

Churn Rate acts as a window into the dynamic nature of your sprint backlog. By understanding the scope changes during a sprint, teams can identify and address volatility, fostering a more stable and predictable development environment.

Optimizing Workflows:

SEI's Churn Rate empowers teams to optimize workflows by pinpointing areas of change mid-sprint. This insight allows for targeted strategies, ensuring that the development team can adapt swiftly and stay on course despite evolving project requirements.

Enhancing Collaboration:

With Churn Rate, collaboration between product managers and engineers reaches new heights. The metric provides a common ground for discussions, enabling both teams to make informed decisions and align efforts seamlessly.

The Formula Unveiled:

Churn Rate = (Points added mid-sprint + Points removed mid-sprint + Positive difference of changes in planned issues) / Points committed at the start of the sprint

  • Points added mid-sprint: The sum of story points for items added during the sprint.
  • Points removed mid-sprint: Identifies the reduction in story points due to the removal of items during the sprint.
  • Positive difference in planned issues: Reflects the positive changes in story points for planned issues during the sprint.
