Solution Architect Guide

As a solution architect, you are accountable for ensuring AI-assisted delivery scales without architectural drift. In this framework, your role is to define architecture guardrails, design role-agent boundaries, and enforce governance so every agent-driven contribution remains traceable, secure, and aligned to target-state architecture.

What This Guide Covers

Section	Outcome
Reference Architecture	A practical blueprint for embedding role-based AI agents into enterprise systems
Agent Contracts and Handoffs	Standard contracts that keep each role-specific agent inside architectural boundaries
Governance Enforcement	Governance gates and decision rights that prevent uncontrolled agent behavior
Architecture Assurance Metrics	Operational metrics that reveal architecture drift, control failures, and remediation needs

Primary Standards

• PRD-STD-005: Documentation Requirements
• PRD-STD-007: Performance & Quality Gates
• PRD-STD-009: Autonomous & Multi-Agent Governance

Prerequisites

To apply this guide effectively, you should:

• Have experience reviewing or approving architecture decisions across at least one production system
• Understand your organization's reference architecture, integration boundaries, and deployment model
• Be able to collaborate with Platform, Security, Compliance, and Engineering leadership on enforcement decisions
• Have access to architecture artifacts (ADRs, diagrams, interface contracts, platform standards)
• Be familiar with the canonical Agent SDLC Orchestration model if your organization is using multi-agent workflows

Guiding Principles

1. Architecture boundaries are governance boundaries. If an agent can cross a boundary without controls, the architecture is not enforceable in practice.
2. Standardize handoffs, not just outputs. Architectural drift often appears at integration points and agent transitions, not within individual code changes.
3. Prefer reusable context packs over one-off reviews. Teams scale faster when architectural constraints are published and consumable by humans and agents.
4. Enforce in CI/CD where possible. Manual architecture review remains necessary, but repeatable checks belong in pipelines.
5. Measure drift, not only compliance. A passing release today does not prove long-term architectural stability.

Getting Started

1. Define a role-agent catalog covering all roles in Role Guides Overview.
2. Publish architecture context packs and approved integration patterns for all delivery teams.
3. Implement governance checks for agent identity, execution scope, and handoff evidence in CI/CD.
4. Establish monthly architecture conformance reviews with CTO, Platform, Security, and Compliance.

Key Relationships

Role	Shared Responsibility
CTO	Enterprise architecture direction and policy authority
Platform Engineer	CI/CD enforcement of architecture and governance controls
Security Engineer	Agent runtime hardening, security review, and risk acceptance
Compliance Officer	Audit evidence design and regulatory defensibility
Development Manager	Team-level adoption and review capacity alignment

Next Steps

1. Start with Reference Architecture as the primary entry point for this role.
2. Review the role's key standards in Production Standards and identify your ownership boundaries.
3. If your team is implementing controls now, use Production Rollout Paths for sequencing and Reference Implementations for apply paths and downloadable repos.
