The Same Questions, Over and Over
"Why do my automated checks take so long"?
"Why does my pipeline fail"?
"Why do I have to constantly fix my CI pipeline"?
"Why Do My Automated Checks Take So Long"?
What's Actually Slowing You Down
Sequential Execution
One task at a time
Redundant Work
Checks on unchanged code
"Longest Pole in the Tent"
Tasks you're always waiting on
Solution Phase 1: Foundational Setup
Intelligent Build System
Scalable Parallelization
Solution Phase 2: Continuous Improvement
Pipeline Metrics
Task Splitting
Company 1 - Accelerating Security Platform CI
Reduced CI Times from 2 Hours to Under 30 Minutes!
Filter (Nx Affected)
Replay (Nx Replay)
Distribute (Nx Agents)
"Why Does My Pipeline Fail?"
The Trust Problem
When your CI pipeline becomes unreliable, engineers give up on trying to fix it.
What's Actually Causing the Failure
1
2
3
4
1
Transient network errors or service outages
2
Dependencies on external environments
3
Legitimate build, test, or lint failures
4
Flaky end-to-end or integration tests
Solutions for Failing Pipelines
