Architecture decision records are short documents that capture important architecture decisions, the context behind them, the options considered, and the consequences of the chosen direction. They help teams preserve decision history and reduce confusion over time.

Architecture Decision Record
A repeatable record for decisions that shape the architecture
Clarify what needs a decisionState the problem, business need, constraints, assumptions, and decision scope.
Make the available choices visibleDescribe meaningful alternatives and the relevant benefits, costs, risks, and dependencies.
Record the selected directionCapture the rationale, decision status, ownership, and the standards or principles it follows.
Explain what changes nextDocument effects on delivery, operations, cost, technical debt, risks, and future decisions.
Executive Summary
Architecture decision records make important technical and design choices visible. They are especially useful when teams need to understand why a platform, pattern, integration approach, or standard was selected.
Why Decision Records Matter
Enterprise systems evolve over many years. Team members change, priorities shift, and documentation can become outdated. Decision records give future teams a reliable way to understand past tradeoffs.
What to Include
- Decision title
- Status
- Date
- Context
- Options considered
- Decision
- Rationale
- Consequences
- Related links or references
Common Status Values
- Proposed
- Accepted
- Superseded
- Deprecated
- Rejected
When to Create an ADR
Create a decision record when a choice has meaningful impact on architecture, cost, operations, integration, security, customer experience, or future delivery.
Examples of ADR Topics
- Selecting a CMS architecture
- Choosing an integration pattern
- Adopting a cloud platform standard
- Defining an authentication approach
- Deciding between page based and structured content models
Best Practices
- Keep each record focused on one decision.
- Write in plain language.
- Document tradeoffs, not only the final answer.
- Link related records when decisions evolve.
- Store records where delivery and architecture teams can find them.
Common Mistakes
- Writing records long after the decision was made.
- Capturing only the conclusion without context.
- Creating records for every small implementation detail.
- Failing to update status when decisions are replaced.
Key Takeaways
Architecture decision records are a practical governance tool. They help teams understand decisions, preserve context, and improve architecture transparency across the organization.
Frequently Asked Questions
Are ADRs only for software teams?
No. They are useful for platform, data, content, integration, governance, and operating model decisions as well.
How long should an ADR be?
Most records should be concise enough to read quickly while still explaining the context and rationale clearly.
