What UAT is

UAT is where real users or business stakeholders confirm:

• the product meets their needs
• workflows match business rules

Who performs UAT

• product owners
• business analysts
• customer representatives

QA can facilitate, but UAT is about business acceptance.

Acceptance criteria

Strong criteria are:

• observable
• testable
• unambiguous

Example:

• “When an order is paid, an invoice PDF is available within 30 seconds.”
