Ar — Architecture Roadmap

Purpose & Usage

The Ar Architecture Roadmap Viewpoint is concerned with the evolution timeline for an Architecture to meet the goals of the enterprise.

• Architecture Project Management.
• Developing architectures.

Scope

• Shall contain Architecture Statuses of Architecture Work Products.
• Shall contain Architecture Milestones that define the Architecture Status.
• May show Architecture Projects that schedule a Milestone and define the evolution of an Architecture Status.
• May show Architecture Versions of the Architecture Work Product.
• May trace Architecture Milestones to other row -specific Milestones they correspond to.

Representation

• Timeline view.
• Augmented chart in style of a Gantt Chart. 190

Notes on the Example

This example, similar to other roadmap viewpoints in NAFv4, is how to model the scenario and is important for the understanding of the evolution of the architecture over time and its impact on decisioning. However, the specific representation of the roadmap for the benefit of non-architectural stakeholder readership should be as described in the content of the ‘Representation’ section of this viewpoint definition.
