Enterprise Agentic AI Implementation Guide (Claude Cowork Edition)

Claude Cowork isn't a chatbot — it's an AI agent that runs code on your employees' computers, reads their files, browses with their cookies, and executes tasks unattended. This 23-page implementation guide is written for the C-suite and operations leaders who need to deploy it safely. It covers vendor evaluation (Cowork vs. Copilot vs. Gemini), step-by-step setup, the five-element prompt framework, Green Zone/Red Zone workload classification, shadow AI prevention, enterprise administration, NIST-aligned security controls, cost modeling with ROI projections, and a 12-week implementation roadmap. Includes seven appendices with copy-paste-ready templates: AUP, managed settings JSON, context files, governance checklist, and pilot scorecard. If your organization is considering Claude Cowork, this guide is where you need to begin.
