Shipping better and faster is a constant goal in software development, and developer velocity is a key metric that measures the speed and efficiency of delivering high-quality code and solutions. It includes factors such as deployment frequency, change implementation time, mean time to recovery (MTTR), and percentage of deployments without vulnerabilities. Improving developer velocity can lead to increased business value, adaptability, reduced costs, and enhanced collaboration among team members. However, it's essential to focus on the outcome rather than just increasing metrics, and not sacrifice code quality for speed. The challenge of measuring developer velocity lies in consistency across teams, quality vs quantity, focusing on the outcome, inflating metrics, external dependencies, and hidden factors. To improve developer velocity, identify issues with your process, evaluate your developer tools, address technical debt, foster collaboration and empower developers, monitor and measure performance, avoid implementing too many changes at once, and leverage self-service infrastructure. Spacelift is a platform that can help teams improve their developer velocity by providing automated infrastructure provisioning, configuring, and governing, while also fostering collaboration and increasing productivity.
