Engineering metrics are crucial for assessing various aspects of engineering, including product attributes, process aspects, project progress, and team performance, enabling leaders to improve products, streamline processes, and enhance transparency and prioritization. These metrics differ from key performance indicators (KPIs) as metrics provide standardized measures, while KPIs are goal-specific. They encompass both quantitative and qualitative indicators, the former offering numerical data like deployment frequency and code churn, and the latter providing insights from human feedback. Leading indicators predict future performance, while lagging indicators review past implementations, and input indicators assess resources used. Best practices for integrating metrics into organizations include aligning them with objectives, ensuring their relevance, and leveraging a centralized system for data analysis to drive informed decision-making and continuous improvement. Additionally, utilizing internal developer portals can aid in tracking, analyzing, and applying these metrics effectively.
