SAP operates with three essential environments: Development (DEV), Quality Assurance (QAS), and Production (PRD). In DEV, consultants from each module perform system configurations, enhancements, and developments. Once changes are properly configured and tested in DEV, they are moved to QAS, where integration testing and user acceptance testing (UAT) are conducted to ensure process accuracy. After validation, transports are moved to PRD, the live environment, where the company runs its real business operations. This structure guarantees system stability, minimizes operational risks, improves process quality, and ensures safe change management while protecting business continuity.
