Use cases & scenarios
Compromises
- Proliferation of ADRs without quality control leads to information overload.
- Unclear ownership can result in outdated or conflicting entries.
- Lack of linkage to implementation and backlog reduces usefulness.
- Keep ADRs short and focused; include only relevant context.
- Maintain links to implementation artifacts.
- Schedule regular reviews in retrospectives or architecture forums.
I/O & resources
- Problem statement, alternative options, technical analyses
- Stakeholder feedback, quality requirements, compliance constraints
- Architecture diagrams, cost/operational estimates
- Finalized ADR with rationale and consequences
- Review log and ownership assignments
- Linked tasks/issues for implementation work
Description
The ADR workflow is a structured process for creating, maintaining, and tracking Architectural Decision Records. It standardizes templates, responsibilities, and review cycles to increase transparency and traceability of architecture decisions. It includes templates, workflow steps, and integration points with issue trackers for repeatable decision-making across teams.
✔Benefits
- Improved traceability of architecture decisions over time.
- Facilitates onboarding and knowledge transfer.
- Supports compliance evidence and audit processes.
✖Limitations
- Requires discipline; ADRs quickly become stale without maintenance.
- Not every minor decision warrants a formal ADR.
- Can introduce initial overhead for time and reviews.
Trade-offs
Metrics
- Number of active ADRs
Counts maintained ADRs over a period to overview documentation density.
- Time to finalization
Average time from draft to published ADR.
- ADR links to implementation
Share of ADRs linked to issues/PRs/tasks.
Examples & implementations
Microservice boundary decision
ADR documented splitting a monolith into two services with communication contract.
Authentication provider migration
ADR with migration plan from self‑hosted solution to OAuth provider.
Storage format standardization
ADR defines a unified JSON schema for data persistence.
Implementation steps
Select or create template, agree on format.
Formulate decision question, collect alternatives and criteria.
Create draft, perform peer review, assign ownership.
Publish ADR, link to issues/tasks and review periodically.
⚠️ Technical debt & bottlenecks
Technical debt
- Unclear ADRs create long‑term maintenance burden for the team.
- Unimplemented ADR decisions lead to inconsistent architectures.
- Missing cleanup processes allow stale decisions to accumulate.
Known bottlenecks
Misuse examples
- Using ADR as mere meeting minutes without decision context.
- Publishing ADRs without deriving implementation steps.
- Using ADRs as a substitute for automated tests or metrics.
Typical traps
- Missing links to code/issues reduces practical relevance.
- No clear revisioning leads to multiple conflicting ADRs.
- Too rigid templates prevent pragmatic decisions.
Required skills
Architectural drivers
Constraints
- • Required tool integration (VCS, issue tracker) must be available.
- • Organizational agreement on formats and processes is required.
- • Consider privacy/compliance requirements for sensitive decisions.
