# Effect: Production-Grade TypeScript

Michael defines production-grade software as a long-lived system that remains resilient, observable, testable, predictable, modular, and approachable. [03:25](https://youtu.be/apklpPEgZgw?t=205) [06:57](https://youtu.be/apklpPEgZgw?t=417)

He contrasts shared production primitives with hidden dependencies, one-off retry logic, manual telemetry, and discipline that does not scale. The talk demonstrates Effect with typed dependencies, fallback plans, tool errors, and traces.
