What the public record settles
The preview carries the contents, the introduction, clauses 1 to 3 and every defined term. The concept and principle clauses are named but not public. This site is built to that boundary, not past it.
35 defined terms
Architecture, architecting, entity of interest, concern, viewpoint, model, life history and the rest, each in our words with a test you can apply.
20 clause areas
The concepts and principles, mapped from the published contents and the definitions each builds on, with the limit stated on every page.
9 annex sections
Notes on terms and concepts, and the judgement of architectural significance, section by section, labelled as not stated in the public preview.
The date, and what it is not
ISO records stage 40.99 on 8 September 2026: the DIS was approved for registration as an FDIS. No publication date is recorded. The planning date used here is 15 September 2027, an estimate 330 days from this build.
The comparison behind it is ISO/IEC/IEEE 42010:2022, whose 40.99 stage fell on 3 January 2022 and whose publication followed on 7 November 2022. A ten month gap is plausible, not guaranteed.

Six terms that change the conversation
The vocabulary is the operative part of the document for most readers. These six carry the most consequence for a regulated firm.
Architecture
The fundamental ideas and the essential qualities that appear in an entity within its setting. The ideas include the dec...
Architecting
The whole activity around an architecture: conceiving it, defining and analysing it, expressing and documenting it, comm...
Architecture design
The information needed, and enough, to create, transform or understand an architecture. It comes out of architecting; it...
Architecture description
The work product used to express an architecture. Its purpose determines its scope, and it is complete when it deals wit...
Concern
A matter of interest, relevance or importance to a stakeholder, or one that has an impact on a stakeholder. Concerns can...
Architecture viewpoint
The rules by which an architecture view is created, read and used. A viewpoint is associated with stakeholder perspectiv...
Four concepts, and the split that matters
Clause 4 is not public, but its structure and the definitions it builds on are. These four pages show what each concept asks of a practice.
Architecture design and solution design
The introduction treats the split as basic: two kinds of design, one strategic and enduring, the other detailed and tactical. It also says the two can...
Stakeholder concerns and architectural aspects
The pairing is the discipline at the centre of the practice: a concern belongs to a stakeholder, an aspect belongs to the entity, and the architecture...
Architecture viewpoints and architecture views
The pair is the mechanism by which concerns reach the description. The document treats a viewpoint as associated with stakeholder perspectives, framin...
Life cycle and life history
The four terms give a firm a way to separate the method from the record. Phase and stage are types; life history is what actually happened. That separ...
What to do before publication
1. Name the entity
Write the entity of interest and its boundary. The scope names enterprises, systems, software, products, services and more; a practice that has never drawn the boundary cannot say what it describes.
2. Own one description
Give one architecture description a purpose, an owner and a review date. Completeness depends on the purpose, not on a universal template.
3. Split the design
Separate architecture design from solution design in the method. The introduction calls this a fundamental distinction between two types of design.
4. Register the concerns and viewpoints
A concern belongs to a stakeholder; a viewpoint frames it and produces views. Two registers make the chain visible and auditable.
5. Adopt the terms
Map the 35 terms into the firm glossary with a local example each. One word for two ideas is the defect that survives longest.
6. Record the decision
Write the adoption decision, the owner and the review date. A practice that drifts back to its old vocabulary has not adopted anything.

Forming
Some parts of the practice are in place. The gap is usually the split between architecture design and solution design, or the viewpoint register.
