Dependency peaks hide in averages
Shared services look fine on monthly means while application fan-out quietly sets the next capacity surprise.
Averages smooth away the moments planners need most. Application analytics that only report daily means will miss the fifteen-minute fan-out that saturates a shared store.
When reconstructing dependency load, align clocks across callers and sample the raw pressure events — not only the rolled-up board. Note which retries amplify cost and which paths share risk windows.
The planning brief should name peaks, not just trends. If a dependency cannot be measured at the resolution of your peak, say so — silence is still a finding.
