ANNEXES

Annex A, B and C, read plainly

All three annexes are informative. Annex A places the document in the SQuaRE series, Annex B compares a risk-based and a quality-based approach, and Annex C explains why the document prefers functional correctness to the general word performance. None adds a requirement, and an assessment finding should not rest on one.

Why the label matters. The annexes are the best explanation of what the clauses mean, and they are not requirements. If someone tells you Annex B requires a particular approach, ask which clause does. The guidance can still be the clearest route to the clause.
THE MODEL

The rules this is built from

Every line names its source. The 25 records are written from the published ISO/IEC 25059:2023, in our words, with the clause cited. The change layer is read from the public draft of the second edition and the ISO stage record. Where the public record is silent, the page says so.

25 RECORDS

Clause by clause, and the annexes

Each page states what the model element is, what the 2023 edition said, what the public draft changes, the evidence a reviewer asks for and the common gaps.

The change, labelled

The second edition adds a service model and environmental sustainability, and moves two characteristics to better parents. Each page says which and why.
