Cost per Sprint: Bringing Money to the Retro Table
Sprint 47, 8-person team. The standard retro narrative would be: "Velocity dropped 20%, lots of bug fires, we'll prioritize better next sprint." Same vibe as Sprint 46. Same vibe as Sprint 45. Now add one number to the same retro: total sprint cost was $32,800, of which $11,600 (35%) went to bug-fix tickets versus $14,200 (43%) to features. The team's rolling-average bug share is 18%. That single line, "we doubled our usual bug spend this sprint," moved the team from "we'll do better" to "Sprint 48's first three days are bug-prevention only, full stop."
This article shows how to wire one financial number into a 30-minute retro so it produces decisions, not vibes.
