Site reliability engineers (SREs) and developers often struggle with balancing speed and stability, leading to friction between these roles due to misaligned priorities and lack of visibility into each other's workflows. The "shift left" movement encourages addressing reliability and operational concerns earlier in the development process, promoting shared ownership and reducing friction. By using a unified service catalog, teams can establish clear service ownership, automate readiness checks, and enhance proactive monitoring, improving both incident prevention and response. This approach allows developers to take full accountability for their applications, including reliability, while SREs focus on setting standards and providing high-level support. The unified service catalog acts as a single source of truth, fostering efficient collaboration, faster incident resolution, and improved system reliability. By equipping teams with the necessary tools, this model supports a shared accountability framework where developers manage application reliability and SREs provide guidance for complex issues.
