This document contains Mermaid diagrams for all 5 ArcKit workflow paths based on the Dependency Structure Matrix.
Legend:
- Blue boxes = Foundation commands (Tier 0-1)
- Green boxes = Core workflow (Tier 2-7)
- Orange boxes = Design & Implementation (Tier 8-9)
- Purple boxes = Quality & Operations (Tier 11-12)
- Red boxes = Compliance (Tier 13)
- Gold boxes = Project Story & Reporting (Tier 14)
- Solid arrows (→) = Mandatory sequential flow
- Dotted arrows (-.->) = Recommended dependencies or optional inputs
For private sector and non-UK government projects without AI components.

The Wardley Mapping suite provides a focused strategic analysis pipeline. Value chain decomposition feeds into map creation, which then branches into three parallel analysis tracks.

azure-researchandaws-researchare alternatives toresearchfor cloud-specific projects. Each requires its respective MCP server. datascout discovers external data sources (APIs, datasets, open data portals) and feeds into data-model and research. †gov-reuse,gov-code-search, andgov-landscapeuse the govreposcrape MCP server (no API key required) to search 24,500+ UK government repositories.
