Which statement about Site Acceptance Testing (SAT) is true?

• A. SAT is performed after installation to verify performance in the real environment
• B. SAT is conducted before shipping from factory
• C. SAT replaces FAT
• D. SAT is optional

Answer: (B)

Site Acceptance Testing is about proving the delivered system will meet the customer’s requirements in the environment where it will operate. Conducting SAT before shipping from the factory means checking that the equipment, its interfaces, and the required functions align with site expectations while still under factory controls. Addressing any gaps before the unit leaves the plant reduces risk, avoids costly rework at the site, and provides a solid acceptance package when the system eventually arrives. While testing after installation at the site is important for commissioning and confirming real‑world performance, the pre‑shipment SAT emphasizes verifying acceptance criteria early. It’s not a replacement for FAT, which validates factory readiness first, and SAT is not typically optional because formal acceptance hinges on meeting the contract terms.
