Reducing CI Pipeline Time

Cut CI build times from 18 minutes to under 5 minutes to restore developer flow and increase shipping frequency.

The full NCT chain

NNarrative

“Our CI pipeline takes 18 minutes on average. Developers are context-switching during the wait, losing flow, and shipping slower as a result. Our best engineers are most affected because they're iterating fastest. Internal surveys show CI wait time is the #1 developer experience complaint. If we get CI under 5 minutes, we expect measurable improvements in shipping frequency and developer satisfaction.”

CCommitment 1

Audit and parallelize the three slowest CI pipeline stages

TTasks

Profile each CI stage to identify bottlenecks
Restructure test stages to run in parallel
Separate unit tests from integration tests
Benchmark before and after parallelization

CCommitment 2

Migrate test suite to run against a dedicated test DB instead of shared staging

TTasks

Set up dedicated test database infrastructure
Update test configuration to use test DB
Migrate test fixtures and seed data
Verify test isolation and data cleanup

CCommitment 3

Add pipeline caching for node_modules and build artifacts

TTasks

Implement dependency caching layer
Add build artifact caching between stages
Configure cache invalidation rules
Monitor cache hit rates and adjust TTL

When to use this

Context

Use this NCT when developer satisfaction surveys or retros consistently surface CI wait times as a pain point. Especially valuable when you can correlate slow CI with decreased shipping frequency or increased context-switching.

Analysis

Why this NCT works

This Narrative reframes infrastructure work as a developer experience problem tied to shipping velocity — making it easier to prioritize against feature work. The Commitments are technical but specific, and each one independently moves the metric. Engineering leadership can track progress without needing to understand every implementation detail.
