Engineering team of 30 was spending 35% of sprint time on manual QA, re-running failed builds, and chasing flaky tests. Velocity was dropping quarter over quarter.
Wasted sprint time dropped from 35% to under 10%. Engineering cost per feature decreased by approximately 22% over the following quarter.
Context
A Series B e-commerce company had scaled their team but not their test infrastructure. Manual QA and flaky CI were quietly draining a third of every sprint before a single feature was touched.
Approach
- 01Week 1: Instrumented CI to surface the top failure sources by frequency and time cost
- 02Week 2: Designed automated regression suite for the 8 highest-risk checkout paths
- 03Weeks 3–4: Shipped automation, introduced test quarantine policy, and established a CI health metric for ongoing tracking
Result
Wasted sprint time dropped from 35% to under 10%. Engineering cost per feature decreased ~22% over the following quarter.
