Subdomain overview canvas

As explained in Architecture Modernization: Socio-technical alignment of software, strategy, and structure

A visual canvas for recording and evaluating key information about a candidate subdomain.

A subdomain overview canvas visualizes the key information about an individual candidate subdomain, helping teams decide whether it is a good boundary option. section 9.5 section 9.4.5

Use the canvas to sense-check the candidate subdomain by asking:

• Would a single team reasonably own all of its events? section 9.4.5
• Do business rules and features require these concepts to change together? section 9.4.5
• Do internal or external people care about only some of the concepts? section 9.4.5
• Does each event seem relevant to the subdomain’s stated purpose? section 9.5

How Architecture Modernization: Socio-technical alignment of software, strategy, and structure covers it

How deep it goes

Guides purpose, event-relevance, team-ownership, shared-change, and stakeholder checks before iterative boundary refinement.

Examples

Uses grouped EventStorming events, candidate subdomains, and a Miro canvas as analysis artifacts.

What it assumes

Assumes candidate events and subdomain options from EventStorming; begins with purpose and relevance checks.

What you can do after

Evaluate a candidate subdomain by checking event relevance, team ownership, shared change, and stakeholder focus.

How it connects

Connects candidate subdomains with EventStorming, domain boundaries, team ownership, business rules, and process modeling.
