The text discusses the challenges of managing multiple environments in continuous deployment and compares two philosophies: "Per Environment Config" and "Global Config." While Statsig supports both, it optimizes for the Global Config approach, which enhances engineering efficiency by reducing errors and speeding up troubleshooting. This approach allows for easy viewing of feature gate exceptions across environments and testing with real data to diagnose issues. However, it may complicate change management due to necessary approvals in production, which can slow down iteration in development and staging. The text also highlights the importance of building strong experimentation cultures and learning from failures, with references to key insights from industry experts and experiences at companies like Facebook and Statsig. Additionally, it touches on the evolution of web experience platforms and the role of A/B testing in providing reliable evidence for product strategies.
