Solution Architecture Review & Assessment
Independent solution architecture review and assessment — evaluating design quality, EA alignment, integration fit, and implementation risk before you commit.
Understanding This Service
What It Is
An independent review of a proposed solution architecture — evaluating design quality, alignment with enterprise architecture principles, integration fit, and implementation risk — delivered before the solution is committed to development or procurement.
Who It's For
Enterprise architects, solution delivery leads, and IT governance boards reviewing solution proposals from internal teams or external vendors, where an independent quality check is required before architectural decisions are locked in.
When It's Needed
Before approving a vendor solution proposal, prior to major solution investment sign-off, or during architecture governance reviews where an independent opinion on design quality and risk is required.
Why Clients Request This Service
Unvalidated Solution Proposals
Integration Fit & Dependency Risks
EA Principles Compliance Gaps
Implementation Risk Underestimated
Scope of Testing
Scope is tailored per engagement, but most reviews draw from the following.
Architecture Design Review
Structured review of the proposed solution design against TOGAF-based quality criteria, design principles, and architectural patterns.
EA Principles Alignment
Assessment of alignment with enterprise architecture principles, technology standards, and the approved platform catalogue.
Integration Fit Assessment
Evaluation of integration approach, data flows, and API design against the enterprise integration architecture.
Risk Assessment
Identification of implementation risks, technology dependencies, and potential design flaws before they become costly to correct.
Architecture Quality Scorecard
A structured quality scorecard summarising design strengths, gaps, and recommendations for each review dimension.
How We Run This Engagement
Documentation Collection
Collect solution architecture documentation, vendor proposals, integration specifications, and relevant EA artefacts.
Architecture Design Review
Review the proposed solution design against TOGAF-based criteria, EA principles, and relevant technology standards.
Integration & Dependency Analysis
Assess integration approach, API design, and data flows against the enterprise integration architecture and dependency landscape.
Risk Identification
Identify implementation risks, design gaps, and assumptions that require validation before architectural commitment.
Review Report & Recommendations
Deliver a structured review report with architecture quality scorecard, findings, and prioritised recommendations.
What You Walk Away With
Solution Architecture Review Report
A structured review report covering design quality, EA alignment, integration fit, and implementation risk findings.
Architecture Quality Scorecard
A scored assessment across key architectural quality dimensions with clear pass, concern, and fail indicators.
Risk Register
A prioritised register of identified implementation risks and design gaps, with recommended mitigations.
Recommendations Summary
A concise summary of priority recommendations for the solution design team or architecture governance board.
What Makes Our Testing Different
A Solution Architecture Review provides the independent quality gate that governance boards and investment committees need before committing to a proposed design. Portamus applies TOGAF-based quality criteria to assess design soundness, EA alignment, integration fit, and implementation risk — delivering a structured scorecard and prioritised recommendations in 1–2 weeks.
Solution Architecture Review vs. Solution Architecture Assessment
The terms solution architecture review and solution architecture assessment are often used interchangeably, and our engagement covers both. A review is typically a governance checkpoint on a single proposed design — validating it before build or procurement sign-off. A solution architecture assessment takes a broader, evidence-based look at design quality, integration fit, and delivery risk, scored consistently across one or several candidate designs. Whether you need a fast independent review of a single vendor proposal or a structured assessment across competing options, the methodology and TOGAF-based quality criteria are the same.
What a Solution Architecture Review Covers
Every review assesses the proposed design across the dimensions that most often drive cost and delay after commitment: design soundness against proven architectural patterns, alignment with your enterprise architecture principles and technology standards, integration and API fit against the existing landscape, and implementation risk. Findings are captured in an architecture quality scorecard with clear pass, concern, and fail indicators, so decision-makers get an unambiguous independent opinion rather than a narrative.
When to Commission a Review or Assessment
Commission a solution architecture assessment before approving a vendor proposal, ahead of a major solution investment sign-off, or as a scheduled architecture governance checkpoint. Where the question is less about a single design and more about the maturity of your architecture practice as a whole, an Architecture Maturity Assessment is the better-fitting engagement — and the two are frequently commissioned together. Both build on our TOGAF-certified delivery.
