Ship Faster, Reduce Risk, and Build Scale with Feature Flags
The document discusses the advantages of using feature flags in software development to improve deployment speed, reduce risks, and manage scale. Feature flags act as decision points in code that can be adjusted at runtime, allowing for safer releases and efficient management of features. Additionally, it highlights LaunchDarkly's platform features for managing feature flags, including targeting, logging, and a centralized dashboard.
