Direct answer
The 2024 DORA cohort shows elite teams sustaining low CFR (sub-5%) at high deploy frequency (40+ per week) through small-batch deploys and fast rollback paths DORA 2024 Report2024. The naïve "deploy less to break less" hypothesis is not supported by the dataGoogle Cloud DORA 20232023.

The small-batch hypothesis

Smaller deploys are easier to reason about, easier to roll back, and limit blast radius. Teams shipping 50+ deploys per week run smaller diffs on average and detect failures in seconds, not hours. The cost of a failure scales sub-linearly with deploy size in those cohorts.
