What it means here
The activity that shows the system meets the acquirer's stated needs.
It uses the acquirer's criteria and, where possible, the acquirer's own people.
How to use it
The term appears in the register wherever the distinction changes what a person must do. A policy that uses the word without the distinction is a policy that cannot be tested. The practice pages link back to this definition so the reader can check the meaning before signing a row.
Use it once in the scope note, once in the role table and once in the evidence index. If the three uses disagree, the file is not ready. The definition is narrow on purpose: a broad definition lets two teams believe they agree when they do not.
The practices that depend on it
Every practice in the register is written to be testable, which means the terms in it have to be concrete. Start with the register, then read the practice that carries the term in its statement. If the term is still unclear after that, the row is not ready to sign.
