Aligning Architecture with Responsibility Indices
summary
Proposes a lightweight process called Responsibility Indices that maps each named responsibility to the actual code locations where it’s implemented, plus an attached quality/readiness score (dark red / orange / yellow / green), refactoring plans and rules of engagement for changes. Recommends keeping about seven responsibilities per level (7±2). Applied to a pipeline-style system it exposes responsibilities split across components, drives targeted refactors, and—per a Tesla-derived experiment—produces clearer business conversations about why red areas slow feature delivery. Assessment is largely team-judgment based.
