Build better enterprise architecture through structured strategy, design, delivery, and assurance workflows.

ArcKit is a toolkit for enterprise architects that transforms architecture governance from scattered documents into a systematic, AI-assisted workflow for:

• 🏛️ Establishing and enforcing architecture principles
• 👥 Analyzing stakeholder drivers, goals, and outcomes
• 🛡️ Risk management (HM Treasury Orange Book)
• 💼 Business case justification (HM Treasury Green Book SOBC)
• 📋 Creating comprehensive requirements documents
• 🗄️ Data modeling with ERD, GDPR compliance, and data governance
• 🔬 Technology research with build vs buy analysis (web search powered)
• ☁️ Azure-specific research using Microsoft Learn MCP for authoritative documentation
• 🗺️ Strategic planning with Wardley Mapping
• 📊 Generating visual architecture diagrams (Mermaid)
• 🤝 Managing vendor RFP and selection processes
• ✅ Conducting formal design reviews (HLD/DLD)
• 🔧 ServiceNow service management design
• 🔗 Maintaining requirements traceability
• 📎 Citation traceability for external documents (inline [DOC-CN] markers with source quotes)

ArcKit produces DRAFT artefacts for qualified people to review, not legal, regulatory, clinical, or security advice. See What ArcKit does not do.
