SA Five Hats Model

As a Solution Architect, switch roles across scenarios. This Skill supports all five modes:

Core Principle: Batch work by "hat," not by topic. During discovery, only discover — don't design. During sales, sell — don't get bogged down in design.

Seven Iron Laws of Solution Architecture

1. You sell solutions, not technology — Solution ≠ technology stack. Solution = choosing the right problem + accepting constraints + finding integration points + considering operational costs + managing stakeholders.
2. NFRs are the main course; functional requirements are just appetizers — A good SA writes: "Login p99 ≤ 400ms at 5000 RPS, 99.95% availability, Admin mandatory MFA, SOC 2 audit retained 7 years."
3. Boring decisions beat clever designs — Unified naming conventions, ADR templates, IAM patterns, and key management are more valuable than fancy custom architectures.
4. Spend more time in conversations, less in diagrams — The highest-leverage skill: walking into a room with five people holding different opinions and walking out with a signed decision.
5. Reversibility is the highest decision dimension — Isolate one-way doors (cloud provider, identity store, core data model); move quickly through two-way doors.
6. Design for the "second-best engineer" — Assume the person inheriting your system is an engineer on a Tuesday afternoon, 3 months removed from this project, with only half a Slack thread as reference.
7. Writing is the operating system — ADRs, RFP responses, runbooks, risk registers. SAs who write clearly scale their influence faster.

Architecture Methodology Toolbox

This Skill integrates three industry-standard architecture methodologies, switching flexibly by scenario:

C4 Model (Software System Architecture Visualization Magnifying Glass)

> Recommendation: Level 0 System Landscape → C1 Context → C2 Container — three layers cover 90% of scenarios. C3-C4 code diagrams are only for critical modules.

C4 Model "Map-Style Zoom" Philosophy

The C4 Model (created by Simon Brown) draws design inspiration from map zoom paradigms: System Context → Container → Component → Code, progressively drilling into technical detail. Core idea: different audiences need different levels; no single diagram fits everyone.

Diagrams as Code — Three Musketeers

> Practical Advice: For presales proposals, use draw.io to generate ultra-high-quality editable versions. For Pipeline/CI environments, choose PlantUML (programmable batch generation). For team collaboration, choose Mermaid (GitHub/GitLab native rendering). For heavy C4 usage, choose Structurizr DSL (C4-native philosophy).

ADM Three Iteration Levels

> Practical Advice: For presales proposals, typically only a lightweight path of "Preliminary → Phase A → Phase B (summary) → Phase C/D (summary) → Phase E" is needed — not the full 8-phase implementation. However, understanding the complete lifecycle helps accurately scope architecture boundaries in high-level proposals.

Wardley Mapping Strategic Decision Framework

Wardley Mapping (created by Simon Wardley) is a strategic decision framework that visualizes the position and evolution stage of each component on the value chain, helping enterprises make key decisions on build/buy/outsource/standardize.

Value Chain Visualization

The basic structure of a Wardley Map: the vertical axis is "Visibility to User," the horizontal axis is "Evolution Stage," and components are arranged left to right along the value chain, from user needs to infrastructure components.

Four-Stage Evolution Model

Cynefin Framework: Four Context Decision Methods

> Practical Advice: In presales proposals, 60% of architecture problems fall into the "Complicated" quadrant (requiring architect professional analysis), 20% into "Clear" (existing best practices), 15% into "Complex" (requiring exploration and validation), and 5% into "Chaotic" (generally outside presales scope). When encountering "Complex" quadrant problems, don't try to give deterministic answers — providing "exploration paths" and "validation approaches" is more professional.

Phase 1: Requirements Understanding & Client Material Analysis

1.1 SPIN Selling Methodology

After receiving client requirements, use the SPIN method for structured analysis:

1.2 Client Material Analysis Process

Step 1: Thoroughly Read All Client Materials
- Supported formats: .pptx / .docx / .pdf / .jpg / .png / .xlsx / text
- Clients typically provide: research reports, existing process diagrams, pain point descriptions, blueprint drafts (if available), requirements specifications

Step 2: Cross-Reference Analysis
- Cross-compare multiple documents
- Mark contradictions as "To Be Clarified"
- Mark gaps as "To Be Supplemented"

Step 3: Output Structured Analysis Report

## Client Requirements Analysis

### Client Profile
- Industry/Domain
- Enterprise scale (employees/revenue)
- IT maturity (Level 1-5, with supporting evidence)
- Key stakeholders (2×2 influence/power matrix)

### Business Current State
- Core value chain/business processes
- Existing system inventory (including tech stack, vintage, operational status)
- Data asset status (structured/unstructured, volume, quality)
- IT team size and capability

### Pain Points & Challenges (Prioritized)
- P0 (Critical): Directly impacts business operations
- P1 (Severe): Significantly impacts efficiency or quality
- P2 (General): Local optimization opportunity

### Goals & Expectations
- Business goals (quantifiable)
- Technical goals (quantifiable)
- Expected ROI / payback period

### Constraints
- Budget range (hard constraint / soft constraint)
- Timeline (deadline / desired)
- Technology stack preferences/restrictions (why)
- Compliance/security requirements (classified protection, GDPR, industry regulation)

### Opportunity Identification
- AI/intelligent opportunities (efficiency improvement / decision support / experience upgrade)
- Process reengineering opportunities (automation / de-manualization / serial-to-parallel)
- System integration opportunities (data connectivity / capability reuse)
- Data value mining opportunities (reporting → analysis → prediction → decision)

Key Rules

• No guessing: Mark information not present in materials as "To Be Confirmed" and list recommended verification methods
• Quantification first: Extract quantitative metrics wherever possible; provide industry benchmarks when not possible
• Cross-reference analysis: Cross-correlate multiple documents; proactively flag contradictions/inconsistencies
• NFR first: Pay attention to non-functional requirements (performance, security, availability, scalability) from the start

---## Phase 2: Research & Meeting Support

2.1 Research Meeting Agenda Design

Based on requirements analysis, generate meeting agendas using the five-step method:

## Research Meeting Agenda

### Basic Information
- Topic / Time / Location / Attendees (mark decision-makers)

### Agenda
1. Opening & Goal Alignment (5min) — What we aim to achieve by the end of today
2. Business Current State & Pain Point Confirmation (20min) — SPIN dimension-by-dimension confirmation
3. Technical Environment & Constraints Assessment (15min) — System inventory, tech stack, limitations
4. Solution Direction Preliminary Discussion (15min) — Our initial thinking, client feedback
5. Next Steps Alignment (5min) — Information supplement list, next meeting time

### Information Collection Checklist (Gap List)
- Ranked by confirmation urgency, with responsible party noted

### Anticipated Q&A (Q&A Prep)
- Grouped by topic (Technical/Commercial/Implementation/Security/Operations)

2.2 Meeting Minutes Standardized Template

## Meeting Minutes

3. If not installing → inform impact: no offline editing, no CLI batch export, inconvenient collaboration, potential formatting issues in proposal diagrams
4. If user insists on not installing → recommend VS Code extension hediet.vscode-drawio (in-IDE editing, lightweight solution)

General Delivery Standards

• Dual-file delivery: .drawio source file + .png preview, same name, same path
• Independent storage: All diagrams in project_folder/diagrams/ directory
• Naming convention: [Diagram Type]-[Topic]-V[Version].drawio
• Proposal references: Only reference .png in documents, do not embed .drawio

Professional Diagramming Principles (from Draw.io Style Guide Best Practices)

draw.io XML File Structure Template

Generated .drawio files must include complete XML structure:

<mxfile host="Claude" modified="YYYY-MM-DD" agent="Claude Code" version="24.0.0">
  <diagram name="Page-1" id="Page-1">
    <mxGraphModel dx="1600" dy="1200" grid="1" gridSize="10" guides="1" tooltips="1" 
                  connect="1" arrows="1" fold="1" page="1" pageScale="1" 
                  pageWidth="1600" pageHeight="1200" math="0" shadow="0">
      <root>
        <mxCell id="0" />
        <mxCell id="1" parent="0" />
        <!-- All graphic elements -->
      </root>
    </mxGraphModel>
  </diagram>
</mxfile>

Diagram Generation Workflow

1. User describes requirements → Confirm diagram type and content scope
2. Output ASCII sketch → For user to confirm layout, hierarchy, main elements
3. After user confirmation → Generate complete draw.io XML, write to .drawio file
4. Attempt PNG export → Auto-export if draw.io CLI available; otherwise inform user of manual export method
5. Inform path → Remind that it can be opened in draw.io for fine-tuning

5.3 Technical Architecture Diagram

Applicable Scenario: Layered display of the technical landscape from infrastructure to frontend applications.

Internet Layered Architecture Five-Layer Model Reference

The standard layered architecture for modern enterprise systems, also the foundational reference model for technical architecture diagrams in presales proposals:

Standard Layering (top to bottom):

┌─────────────────────────────────────────────────┐
│  Access Layer │ Web / Mobile / H5 / OpenAPI / Gateway │  #E3F2FD
├─────────────────────────────────────────────────┤
│  Application Layer │ Microservice Cluster / Business Modules / Job Scheduler │  #E8F5E9
├─────────────────────────────────────────────────┤
│  Platform Layer │ Middleware / AI / Messaging / Search / Process Engine │  #FFF3E0
├─────────────────────────────────────────────────┤
│  Data Layer │ OLTP / OLAP / Cache / Search Engine / Data Lake │  #F3E5F5
├─────────────────────────────────────────────────┤
│  Infrastructure Layer │ Cloud / K8s / Network / Storage / Security Groups │  #ECEFF1
└─────────────────────────────────────────────────┘
    ← Security System (vertical penetration) →  ← Operations System (vertical penetration) →

Key Rules:
- Use horizontal swimlanes or large containers for each layer
- Layer-internal components use rounded rectangles, grouped arrangement
- Security and operations systems use vertical lines/color bars penetrating from top to bottom
- Each layer container fill color has 30-40% color difference from internal component fill colors
- External systems/third-party services placed in the rightmost column as independent area

5.4 Business Process Diagram

Applicable Scenario: End-to-end business processes, approval flows, decision branches, exception handling.

Swimlane Standards:
- Horizontal swimlanes: each row represents a role/department/system
- Swimlane title width 30px (startSize=30)
- Role background colors: human roles light warm, system roles light cool

BPMN Elements Mapped to draw.io:
| BPMN Element | draw.io Shape | Style |
|-----------|-------------|------|
| Start Event | Thin ring | ellipse;fillColor=#C8E6C9;strokeColor=#388E3C |
| End Event | Thick ring | ellipse;fillColor=#FFCDD2;strokeColor=#D32F2F;strokeWidth=3 |
| Task/Activity | Rounded rectangle | rounded=1;fillColor=#FFFFFF;strokeColor=#333333 |
| Gateway (Exclusive) | Diamond | rhombus;fillColor=#FFF9C4, label "X" inside |
| Gateway (Parallel) | Diamond | rhombus;fillColor=#FFF9C4, label "+" inside |
| Data Object | Top-right folded rectangle | shape=document |
| Annotation | Left-folded rectangle | Dashed border, light yellow fill |

Connection Rules:
- Normal flow: Solid line strokeColor=#333333;endArrow=classic
- Message flow: Dashed dashed=1;dashPattern=8 8
- Exception/compensation flow: Red dashed strokeColor=#D32F2F;dashed=1

5.5 Data Flow Diagram (DFD — Level 0-2 Multi-Level)

PPT Design System

Color Schemes

Typography Standards

Design Discipline

• Sandwich Structure: Dark cover+ending, light content slides (or all-dark for premium unified look)
• Every slide must have visual elements: Diagrams/large numbers/icons/photos, no pure text slides
• Left-aligned body text, centered titles only
• No title underlines (hallmark of AI-generated feel)
• No mixed spacing: Uniform 0.3" or 0.5", pick one
• No default blue: Color scheme reflects topic and industry
• No same layout three slides in a row: Vary columns, cards, callouts

PPT QA Process (Must Execute)

1. Slide-by-slide check: text overflow, element overlap, uneven spacing
2. Check diagram sources: PNGs referenced from diagrams/ must be high-res (≥ 1920×1080)
3. Check contrast: text/icons on dark backgrounds must be clearly visible
4. Check content completeness: key slides not missing, key numbers not lost
5. Final check: look for AI traces (title underlines, cookie-cutter layouts)

Global Public Procurement Market & RFP Best Practices

Global Public Procurement Market Size

International RFP Response Framework

When responding to RFPs across different jurisdictions, adapt your approach to local expectations:

| Dimension | US | EU/UK | APAC | Middle East | China |
|---------------|-------|------|-------------|-------|
| Evaluation Model | Best Value / LPTA (Lowest Price Technically Acceptable) | MEAT (Most Economically Advantageous Tender) | Quality + Price weighting; often 70:30 or 80:20 | Technical compliance first, then price negotiation | Comprehensive scoring; technical + commercial + price |
| Page Limits | Often strict; follow exactly | Typically flexible within reason | Varies by country; Japan often strict | Often no strict limits; quality over brevity | Strict; must follow tender document exactly |
| Language | English (Spanish for some state/local) | Local language + English summary sometimes | Local language + English (Singapore, Philippines use English) | Arabic + English (UAE), Arabic (Saudi) | Chinese (Simplified) |
| Compliance | FAR/DFARS (US), Section 508 accessibility | EU directives, GDPR, NIS2, DORA | Local procurement acts, data residency | Local content requirements (In-Country Value/ICV) | Government Procurement Law, MLPS (Multi-Level Protection Scheme), Xinchuang |
| Key Differentiator | Past performance, small business participation | Sustainability, social value, innovation | Relationship, local presence, knowledge transfer | Wasta (relationships), local partnerships, ICV | Localization, domestic IPR, Xinchuang compatibility |
| Bid Bond | Often required (5-20%) | Varies by country | Common (5-10%) | Often required (1-5%) | Often required (bid bond, typically ≤2%) |
| Negotiation Style | Transparent, rule-based | Structured, consensus-driven | Relationship-first, harmony | Relationship-driven, hierarchical | Formal, hierarchical, guanxi matters |

RFP Response Quality Checklist (International)

• [ ] Executive summary tailored to the specific evaluation criteria
• [ ] Compliance matrix completed with "Comply / Partial / Deviate / Alternative" for every clause
• [ ] Technical response structured to mirror RFP section numbering

• [ ] All forms signed, stamped, and notarized as required
• [ ] Submission format exactly matches RFP instructions (electronic portal, physical copies, etc.)
• [ ] Internal review: legal, commercial, technical, delivery — all signed off
• [ ] Red team review completed (independent reviewer simulates evaluator perspective)

---## Phase 8: Cloud Financial Management (FinOps)

FinOps is the IT financial management practice for the cloud era, achieving cloud cost visibility, control, and optimization through cross-functional (Technology + Finance + Business) collaboration. Adding a FinOps perspective to presales proposals shows clients "not just how to do it, but how much it costs and how to save" — the complete picture.

FinOps Three-Phase Cycle

┌──────────┐     ┌──────────┐     ┌──────────┐
│  Inform  │────►│ Optimize │────►│ Operate  │
│  Visibility│     │  Optimize │     │  Operate │
│  (Inform) │◄────│ (Optimize)│◄────│ (Operate)│
└──────────┘     └──────────┘     └──────────┘

• Inform (Visibility): Establish cost allocation tagging system (department/project/environment/application), real-time cost dashboards and budget tracking, Showback→Chargeback maturity path
• Optimize (Optimization): On-demand instances → Reserved Instances/Savings Plans (save 50-70%), Spot instances for non-critical workloads, storage tiering, idle resource identification and release
• Operate (Operations): Automated cost governance policies, budget alerts and anomaly detection, regular review meetings, cost optimization culture building

International Cloud Architecture Patterns

Beyond the standard architecture patterns, the following internationally-recognized cloud architecture patterns should be in every solution architect's toolkit:

1. Strangler Fig Pattern

Origin: Martin Fowler (2004). When to use: Migrating legacy monolithic systems to microservices incrementally.
- Gradually replace specific functionality with new services
- Route traffic progressively from old to new
- Eventually "strangle" the monolith when all functionality is replaced
- Risk: Requires dual-running period; data consistency across old and new systems

2. Event-Driven Architecture (EDA)

When to use: Asynchronous, loosely-coupled systems; real-time data processing; IoT; microservices communication.
- Producers publish events; consumers subscribe and react
- Key patterns: Event Sourcing, Event Streaming (Kafka/Kinesis), Pub/Sub, Event Bus
- Risk: Eventual consistency; event schema evolution; debugging complexity

3. CQRS / Event Sourcing (Command Query Responsibility Segregation)

Origin: Greg Young. When to use: High-read/write ratio systems; audit trail requirements; complex domain models.
- Separate read models from write models
- Commands mutate state; queries read from optimized projections
- Often paired with Event Sourcing: store state changes as an event log
- Risk: Increased complexity; eventual consistency; learning curve

4. Data Mesh

Origin: Zhamak Dehghani (ThoughtWorks, 2019). When to use: Large enterprises with multiple data domains and teams.
- Decentralized data ownership by domain
- Data as a Product — each domain publishes curated data products
- Federated governance — global standards, local implementation
- Self-serve data infrastructure platform
- Risk: Organizational maturity required; governance complexity; tooling ecosystem still maturing

5. Cell-Based Architecture

Origin: AWS Well-Architected Framework. When to use: Ultra-high availability systems; blast-radius reduction; multi-tenant SaaS.
- Each "cell" is a self-contained, independently-deployable unit
- Cells do not share databases, queues, or state
- Routing layer directs traffic to the correct cell
- Risk: Operational overhead; data partitioning complexity; cross-cell communication

6. Multi-Region Active-Active

When to use: Global user base; regulatory data residency; disaster recovery with RTO < 5 minutes.
- Multiple regions serve traffic simultaneously
- Data replication across regions (eventual or strong consistency)
- Global traffic management (Route 53, Cloud CDN, Azure Front Door, Cloud Load Balancing)
- Risk: Data conflict resolution; cost (2x+ infrastructure); operational complexity

│ Revenue Growth (New Biz) │ ...   │ ...    │ $XXX K      │
├─────────────────────────────────────────────────────┤
│ Total Annual Value      │        │        │ $XXX K      │
│ 3-Year TCO              │        │        │ $XXX K      │
│ 3-Year ROI              │        │        │ XXX%        │
│ Payback Period          │        │        │ XX months   │
└─────────────────────────────────────────────────────┘

> Practical Advice: In presales proposals, ROI/TCO is not "nice to have" but "must answer." Client decision-makers (especially CIO/CFO) care most about "how much, how much saved, how long to pay back." It is recommended to establish a dedicated "Investment Return Analysis" chapter in the proposal and speak with data.

Cross-Phase Universal Capabilities

Architecture Decision Record (ADR)

Generate an ADR for every irreversible or high-cost architecture decision:

## ADR-00X: [Decision Title]

### Status
Proposed / Accepted / Deprecated / Superseded

### Context
Why does this decision need to be made?

### Decision
What have we decided to do?

### Options Evaluation
| Option | Pros | Cons | Score |
|------|------|------|------|
| A: [Option A] | ... | ... | ... |
| B: [Option B] | ... | ... | ... |

### Consequences
- Positive:
- Negative:
- Risks:

### Reversibility
- [ ] Two-way door (easily reversible)
- [ ] One-way door (irreversible or extremely costly to reverse)
- [ ] One-and-a-half-way door (reversible but with some cost)

### Related
- Related ADR: [ADR-00X]
- Scope: [Project/Platform/Enterprise]
