What the second edition changes, and what it keeps
Four technical changes are listed in the public draft's foreword. This page sets them against the 2023 edition, then lists every model element whose status changes. The FDIS may differ from the draft; the change is labelled at the level the public record supports.
Alignment with the 2023 product quality model
The normative reference moves from the 2011 product quality model to the 2023 edition, and the model is presented as a table that inherits the newer characteristics.
Quality in use moves to its own base standard
The quality-in-use model is aligned to the 2023 quality-in-use standard, which now sits apart from the product quality model. The top characteristic is relabelled risk mitigation.
A service quality model is added
A new clause covers AI services, based on the service quality models standard, with traceability, service adaptability and customizability.
Environmental sustainability is added
Environmental sustainability becomes a sub-characteristic of performance efficiency, and environmental risk mitigation joins the quality-in-use model.
Every element whose status changes
| Clause | Record | Status | In one line |
|---|---|---|---|
| 2 | Normative references | Amended | The 2011 reference is replaced by the 2023 product quality model and the 2023 quality-in-use model. |
| 3.1 | General terms | Amended | New terms are added for the environment, for control and for selection bias. |
| 3.2 | Product quality terms | Amended | Environmental sustainability is added as a sixth product term. |
| 3.3 | Quality-in-use terms | Amended | Environmental risk mitigation is added. |
| 3.4 | AI service quality terms | New in the second edition | All three terms are new. |
| 5.2 | User controllability | Moved in the second edition | The parent changes from usability to interaction capability, following the 2023 base model. |
| 5.4 | Functional correctness | Amended | The definition is restated against the 2023 base model. |
| 5.7 | Intervenability | Moved in the second edition | The characteristic moves under safety, following the 2023 base model, which makes safety a top-level characteristic. |
| 5.8 | Environmental sustainability | New in the second edition | The characteristic is added beneath performance efficiency in the product model. |
| 6.1 | General | Amended | The model aligns to the separate 2023 quality-in-use standard. |
| 6.3 | Societal and ethical risk mitigation | Amended | The wording widens to potential societal or ethical risk, and the characteristic sits under risk mitigation in the aligned quality-in-use model. |
| 7.1 | General | New in the second edition | The clause and the model are new. |
| 7.2 | Traceability | New in the second edition | New in the second edition, as a sub-characteristic of the service model. |
| 7.3 | Service adaptability | New in the second edition | New in the second edition. |
| 7.4 | Customizability | New in the second edition | New in the second edition, as a sub-characteristic of service adaptability.. |
What it keeps
- User controllability, functional adaptability, functional correctness, robustness, transparency and intervenability remain in the model.
- The six AI-specific sub-characteristics keep their names, though one moves to a different parent characteristic.
- The three informative annexes keep their subjects.
The limit, stated plainly
The FDIS text is not public. ISO sells the FDIS, and no public clause level change list exists. This site reads the public draft of the second edition, which is the document the FDIS was built from, and labels every change as draft. It does not claim that the FDIS says the same thing. When the published edition appears, the record is refreshed and the change is stated against the published text.
Why the base reference matters more than the new clauses
The 2023 edition cites ISO/IEC 25010:2011 as a normative reference. That edition is withdrawn. ISO/IEC 25010:2023 replaces it, with the quality-in-use model moved to ISO/IEC 25019:2023 and the model overview in ISO/IEC 25002. The 2023 edition's own quality-in-use clause therefore rests on a withdrawn base. A requirement set that cites 25059:2023 without checking its base is already reading a superseded vocabulary, before the second edition is published.
This is a factual reading of the reference lists, not a prediction about the FDIS. The second edition's foreword says it aligns to the 2023 models, which confirms the direction.
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.
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.
Open the recordThe 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.
What changesNo invented date
The FDIS is at 50.00. ISO records no publication date. The planning date is an estimate and is labelled wherever it appears.
