Get Started

You don't need everything on day one.

That's worth repeating, because most architecture initiatives fail by trying to do too much too soon. Comprehensive frameworks. Detailed artefact libraries. Governance forums. Tool implementations. By the time the capability is "ready", business priorities have shifted, sponsors have moved on, and the architecture function has a reputation for being slow and theoretical.

XAF takes a different approach: start with the minimum that actually works, then add capability as you prove value.

The Minimum Viable Framework

Here's what you actually need to start doing architecture governance that makes a difference:

1. Guardrails Documented

Even a simple list works. Ten to fifteen key constraints that capture your organisation's current technology direction, security requirements, and strategic priorities

You don't need a comprehensive guardrail library. You need enough guardrails to answer the question: "Can I proceed with this, or do I need to have a conversation?"

Start with:

• 5-10 technology guardrails (approved platforms, integration patterns, hosting standards)
• 3-5 security guardrails (non-negotiable controls, data handling requirements)
• 2-3 strategic guardrails (capabilities being invested in, capabilities being sunset)

2. Decision Record Template

Something you can complete in 15 minutes. Not a 10-page document — a lightweight template that captures:

• What was decided
• Why it was decided (context and rationale)
• What alternatives were considered
• Which guardrails it aligns with (or deviates from)
• What consequences or trade-offs were accepted

The test isn't "did I fill in every field?" It's "could someone unfamiliar with this decision understand why we made it?"

3. Architecture Passport Template

A living document per system that captures the essential context someone needs to understand that system's architecture. Not comprehensive documentation — a navigation aid that answers:

• What does this system do and who owns it?
• How is it built at a high level?
• What are the key decisions that shaped it?
• What's the current health assessment?
• What debt exists and what's the plan?

Someone should be able to read a passport in 15-20 minutes and understand the essential context.

4. Someone Who Can Approve

Even a simple structure works: Lead Architect plus Business Sponsor for decisions that need escalation. You don't need a formal Architecture Authority on day one — you need clarity about who can say yes when a decision requires approval.

5. Clear Escalation Path

Who do you ask when you're stuck? When a guardrail doesn't quite fit? When you need to deviate? A clear escalation path prevents paralysis and ensures decisions don't get stuck in ambiguity.

Quick Start Checklist

Use this to track your initial implementation:

Week 1 Essentials

• Document top 10 technology guardrails
• Document top 5 security guardrails
• Create decision record template
• Create architecture passport template
• Define who can approve (escalation structure)
• Define escalation path for questions and deviations

Month 1 Additions

• Identify current Tier 1 (high-risk) initiatives
• Set up registry folder structure
• Start debt register for known technical debt
• Schedule first architecture review
• Create passports for 2-3 critical systems

Quarter 1 Scaling

• Implement tiered oversight model
• Define formal roles and decision rights
• Establish regular architecture review cadence
• Build out registry with patterns and building blocks
• Connect to delivery methodology checkpoints

Scaling to Your Context

The framework adapts to your situation rather than demanding you change to fit it.

By Team Size

By Organisational Structure

By Delivery Model

What to Add When Scaling

Once the minimum viable framework is working, add capability incrementally based on where you're feeling pain.

Tiered Oversight Model

When you've got enough activity that not everything needs the same scrutiny, implement tiered oversight:

• Tier 1 (High Risk) — New technology, core systems, significant investment, regulatory impact. Active EA involvement at decision points.
• Tier 2 (Medium Risk) — Extends existing patterns, moderate complexity, internal impact. Lightweight checkpoint plus async review.
• Tier 3 (Low Risk) — Standard patterns, low complexity, well-understood domain. Self-certification against guardrails.

Formal Roles and Decision Rights

When you need clarity about who decides what, define explicit decision rights. At minimum:

• Who can approve guardrail deviations (by tier)
• Who owns guardrail lifecycle (creation, review, retirement)
• Who maintains passports and decision records
• Who escalates to executive governance when needed

Architecture Authority / Governance Forums

When you need a regular forum for cross-cutting architectural decisions, establish an Architecture Authority. This isn't a gate everything must pass through — it's a decision forum for issues that cross domain boundaries or require collective input.

GRC Integration

When you need architecture governance to connect with broader risk and compliance functions, establish explicit integration points:

• Guardrails map to risk appetite statements
• Deviations create risk acceptances
• Technical debt feeds risk register
• Tier 1 decisions involve risk representatives

Metrics and Reporting

When you need to demonstrate value and track health, implement basic metrics:

• Guardrail compliance rates
• Decision record coverage
• Passport currency
• Debt accumulation and remediation
• Deviation patterns

Full Registry

When reuse becomes a priority, build out the Architecture Registry with patterns, building blocks, reference architectures, and approved solutions. The registry makes reuse the path of least resistance.

Adding Domain Modules

The Governance Core works regardless of which architecture domains you're addressing. Domain modules add domain-specific guardrails, patterns, and guidance.

Start with your biggest pain point. If security is creating friction, start with the Security Architecture module. If business-technology alignment is the issue, start with Business Architecture. If data is the mess, start with Data Architecture.

You don't need all modules. Many organisations operate effectively with the Governance Core plus one or two domain modules that address their specific needs.

Common Starting Points

"We have no architecture governance"

Start with the minimum viable framework. Focus on guardrails, decision records, and getting the habit established. Don't try to document everything historical — start capturing decisions from today forward.

Week 1: Document your top 15 guardrails. Create a simple decision record template. Identify who can approve.

Month 1: Start creating passports for your most critical systems. Capture decisions as they happen.

Quarter 1: Review what's working, adjust templates, expand guardrail coverage.

"We have governance but it's not working"

Diagnose why it's not working. Usually it's one of:

• Too heavy (simplify — use tiered oversight)
• Not embedded in delivery (integrate at decision points, not parallel)
• No one enforces it (establish accountability and sampling)
• Templates are too complex (simplify — 15 minutes to complete)
• No clear value (focus on enabling speed, not controlling decisions)

"We have architecture silos"

Start with the Governance Core to establish shared foundations, then implement cross-domain traceability:

Strategy → Capability → Information → Technology → Solution

Focus on explicit handoffs between domains rather than trying to have everyone in every meeting.

"We're one architect trying to make a difference"

Use guardrails as your personal checklist. Decision records build credibility with stakeholders and serve as your own memory. Passports ensure you don't lose context when juggling multiple systems.

Start small. Prove value. Build support for expanding the approach.
