2 Normative reference

What this heading covers

The clause names ISO/IEC 25000, ISO/IEC 25010 and ISO/IEC 25020, and it fixes how an edition is picked: a dated reference pins that edition, and an undated one follows whatever edition is current. All three are undated in the draft, which matters: the model can move under the measurement standard when a new edition of 25010 is published, and the measurement framework can move too. The three are not decoration. 25000 supplies the shared vocabulary, 25010 supplies the characteristics and subcharacteristics that every measure is indexed to, and 25020 supplies the measurement concepts and the way a measure is constructed.

What the heading asks of a team

What to put in place before publication

1. Pin the editions of 25000, 25010 and 25020 that your quality plan cites, and write the edition years into the plan.
2. Check whether your measure library is indexed to the 2011 or the 2023 product quality model, because the characteristic names differ between them.
3. Keep the three documents, or a licensed route to them, available to the people who run the measurement programme.
4. Record in the plan that the references are undated, so a new edition is picked up deliberately rather than by accident.
5. Ask a supplier which edition of 25010 its quality measures are built on when it answers a tender.

Where teams usually fall short

• A measure library built on the 2011 model and reported beside a 2023 model without a crosswalk, so usability and interaction capability are used as if they were the same heading.
• A contract that cites 25023:2016 and assumes it pins the model edition, when the model is a separate undated reference.

What happens next

Clause 3 sets the fifteen terms the draft uses itself, and points to 25000 for the rest. The glossary page carries all fifteen with the page each one shapes.
