Terms and definitions

The clause fixes the vocabulary. Entries appear in systematic order, an index sits at 3.1, and the terms fall into five groups: architecting, entity related ideas, architecture design, architecture description, and the life cycle of an entity.

What this unit settles

The vocabulary is the operative part of the document for most readers. It fixes 35 terms across the five categories and gives each a definition with notes. It points to the ISO, IEC and IEEE terminology databases and to ISO/IEC/IEEE 24765 for terms outside this document. The systematic order is deliberate, following the ISO/IEC Directives, with the index provided for lookup.

What to do in your practice

Adopt the 35 terms into the firm glossary with a local example for each. Where the firm uses a different word for the same idea, record the mapping rather than maintaining two languages. Where the firm uses the same word for a different idea, treat that as a defect to fix first.

Who it binds

The organisation and the architecture practice. This unit is not a shall requirement; the claim level states what it is.

Evidence an auditor or regulator asks for

  • The firm glossary mapped to the 35 terms, with a local example per term.
    An auditor asks whether the firm uses a stable vocabulary.
  • A list of local synonyms and the term they map to.
    Prevents two words for one idea and one word for two ideas.
  • The glossary owner and review date.
    Shows the vocabulary is governed.
  • A sample of descriptions checked against the glossary.
    Proves the glossary is used.
Ask your teamWhich word does this firm use for a different idea than the document does, and what confusion has it caused?

Common gaps this page catches

  • The glossary is a tool export and is not mapped to the standard vocabulary.
  • The same word carries different meanings in different teams.
  • No one owns the glossary.

What to prepare before publication

Map the firm glossary to the 35 terms. Mark synonyms, conflicts and missing terms. Assign an owner and a review date. Fix the conflicts before adding new terms.
