SAT is carried out at the site of a vendor or in-house at a specific stage prior to release of the software to the next phase of the lifecycle.


Acceptance and agreement of any anomalies found with the product at a given phase in the project lifecycle.

Effective SAT is achieved by early preparation of a test plan and clear concise test goals.The client, or representatives of the client, should be present during this phase of testing. This will help to give the client confidence that the system is as they originally desired, and as such is "fit for purpose". Invariably, faults found at this stage of testing are expensive to fix, although if the Risk-based testing has been performed successfully, then these faults will have been found early and thus expenses will be kept to a minimum.
