A5 – Architecture Status

The A5 Architecture Status View specifies the version number and approval status of the architecture.

Concerns Addressed

• Architecture Management & Review.

Background

Since NAF 3.0, it has been possible to assign version numbers to views and specify their approval dates. In NAF v4.0, this is integrated with the meta-model’s generic project & milestone approach so that architecture releases are tracked against the architecture delivery project.

Usage

• Architecture project management.
• Release scheduling.

Representation

The A5 View is based on the meta-model’s generic project structure, but A5 information is usually best summarised in a simple table or text document.

Detailed View Description

The A5 presents a subset of the NAF 3.1 NAV-1 view. It concentrates on the versioning and status information of the architecture:

Although the A5 is usually presented as quite a simple text document or table, the underlying meta-model is much more capable, assigning architecture releases to project milestones and using succession relationships between versions. A6 and Ar views reveal more of the underlying meta-model.
