Engineering Metrics

Refactoring repays earlier technical debt and restores future engineering capacity. High rework indicates that requirements may be unstable, design may be poor, or both. Developer analytics can make technical debt visible by separating new code, cleanup, and mistake-fixing effort. Process metrics should identify organizational bottlenecks and improve the work environment rather than surveil individuals. Keep-the-lights-on metrics show how much capacity is spent merely sustaining existing systems. Tactical engineering metrics should evaluate concrete delivery and execution outcomes instead of raw activity. Architectural metrics should track maintainability, reliability, complexity, technical debt, and whether decisions help future work.
