What You Can Do

You can systematically evaluate architectural options by building decision matrices, identifying trade-offs, and documenting design rationale. This skill generates comparison frameworks, risk assessments, and architecture decision records (ADRs) that help you choose between competing approaches based on concrete criteria like performance, scalability, cost, and team capabilities.

Features

Trade-off analysis matrix

Compare 3+ architecture options across weighted criteria (cost, performance, scalability, maintainability)

Architecture decision records (ADR)

Generate formal ADR templates documenting decisions, context, and consequences for future reference

Risk assessment framework

Identify architectural risks and mitigation strategies for each approach

Comparison tables

Create side-by-side technical comparisons (microservices vs monolith, SQL vs NoSQL, on-prem vs cloud)

Cost modeling

Estimate infrastructure, operational, and team costs for different architectural choices

Stakeholder alignment template

Document concerns and priorities from architects, product, finance, and ops teams

Implementation roadmap

Break down architectural transitions into staged, deliverable milestones

Scalability projection

Model growth scenarios and architectural capacity limits

Recommended decision: Monolithic for MVP (18 months), migrate to microservices at 500K users.

Risk: Team lacks Go/Kubernetes expertise. Mitigation: Hire 1 senior SRE, 3-month ramp-up.
