Domain Governance Reflection Resource
Portfolio Rationalisation Worksheet
Use this worksheet to decide which domains should be kept, consolidated, retired or investigated. Retiring a domain is a governance decision, not merely a cost decision.
Portfolio review table
Classify each domain by purpose and governance intent. Keep unknowns visible rather than forcing a decision.
| Domain / subdomain | Purpose | Business owner | Technical operator | Type | Dependent services | Email sending? | Renewal owner | Decision | Retirement risk | Next action |
|---|---|---|---|---|---|---|---|---|---|---|
| Active / defensive / legacy / campaign / unknown | Yes / No / Unknown | Keep / consolidate / retire / investigate | ||||||||

Retirement checklist
- The domain has a named business owner approving retirement.
- Dependent web, email, identity, API and supplier services have been checked.
- Redirects, customer communications and search implications have been considered.
- Email sending and inbound mail dependencies have been confirmed.
- The risk of third-party re-registration and impersonation has been assessed.
- Retention, redirection or defensive holding has been considered before lapse.
