Why do staging tests pass but production still breaks?

Staging simulates a sanitized world — different configs, tiny data, no real latency. Prod hits with full chaos: mismatched endpoints, massive scales, flaky integrations.

How much do production bugs from staging really cost?

10-100x more than dev-caught ones, per IBM data. Plus 20-25% team velocity lost to fixes — that's weeks per sprint.

Can you make staging actually work like production?

Partially: sync configs, mirror data volumes, inject chaos. But true fix? Canary deploys and prod subsets. Staging alone? False security.
