Q1. What is the real purpose of having separate Dev, QA, UAT, and Prod environments in Dynamics 365?

Isolates development work from live business data to avoid disruption.
QA helps validate functionality without real-world risks.
UAT ensures end-users approve changes before go-live.
Production remains stable and trusted by users at all times.
Each layer acts as a gatekeeper for quality and readiness.
Reduces risk of untested code affecting critical business operations.

Q2. Why should UAT not be treated as a test replica of QA in a Dynamics 365 project?

UAT focuses on user validation, not just technical correctness.
It uses business-like data and simulates real processes.
QA checks system bugs, UAT checks user experience and expectations.
UAT gives the green signal from the business, not just IT.
Mixing UAT with QA leads to incomplete business acceptance.
