We’re trying to make our pre-production validation process more reliable, and I’m curious how others handle it in practice.

Specifically:

• Do you validate with simulators first, or only against the vendor/client test environment?
• What are the most common failure points before go-live?
• What test cases are considered mandatory?
• How long does a typical validation cycle take?

Interested in practical workflows and lessons learned from real implementations.
