Cutting CI Flake: Accelerate Feedback Loops for Engineering Teams
Reduce CI flake and pipeline times to enhance feedback loops and improve delivery metrics.
CI flakiness is a business risk that erodes stakeholder trust and leads to costly delays.Back to all posts
Your last deployment didn't just fail; it cost you $50,000 in refunds. A single line of legacy code brought down your entire payment system during Black Friday. In today's fast-paced development environment, the stakes are high. Continuous Integration (CI) flakiness isn't just an annoyance; it's a business risk that er
For engineering leaders, the urgency to address CI flake and pipeline inefficiencies cannot be overstated. High change failure rates and extended recovery times not only hinder your team's productivity but also erode stakeholder trust. When your CI/CD pipeline is unreliable, it can lead to delayed releases, increased
To implement a more reliable CI/CD process, follow these actionable steps: 1. **Implement CI Pipeline Monitoring**: Use tools like Jenkins, CircleCI, or GitLab CI to monitor your pipelines. This will help identify flaky tests and their impact on deployment times. 2. **Automate Test Retries**: For tests that are
3. **Refactor Legacy Code**: Regularly review and update your codebase to eliminate dependencies on unstable legacy code. This will not only reduce flakiness but also improve overall system performance. 4. **Establish a Feedback Loop**: Encourage your development team to report CI/CD issues. Create a culture of open
Establish a regular review cadence to discuss CI performance metrics. This will help in identifying patterns and areas for improvement. By focusing on these steps, you can significantly reduce CI flake, streamline your pipelines, and accelerate feedback loops. **Key Takeaways**: - Prioritize reducing CI flake to
Always validate your CI/CD processes against key metrics: change failure rate, lead time, and recovery time. By doing so, you can ensure that your improvements translate into tangible business benefits.
Key takeaways

Questions we hear from teams
- What is CI flakiness and why is it a problem?
- CI flakiness refers to unreliable tests in a Continuous Integration pipeline that pass or fail inconsistently, leading to wasted time and resources.
- How can I measure the change failure rate effectively?
- Track the percentage of deployments that result in failure compared to total deployments. This will give you a clear metric to address.
- What tools can help reduce CI flake?
- Consider using CI monitoring tools like Jenkins, CircleCI, or GitLab CI, along with test automation frameworks that support retry mechanisms.
