Original Summary

Something I keep having to explain when people ask how risk scoring works in Vast, fan-in and fan-out aren't the same risk and shouldn't be collapsed into one metric. Fan-out: how many things this file depends on. High fan-out = fragile, breaks easily when an upstream dependency changes. Fan-in: how many things depend on this file. High fan-in = dangerous to touch, changing it ripples outward to everything relying on it. A file can have high fan-out and be totally safe to refactor on its own. A file with high fan-in is the one that needs actual review before any change, regardless of how simple the change looks. Curious if others tracking dependency metrics keep these separate or collapse them into a single coupling score, feels like collapsing them loses the part that actually matters for prioritizing review.   submitted by   /u/Ok-Emu-8106 [link]   [comments]
