Enterprise AI at Forterro (ERP group, 2,500+ staff): I built a two-agent Microsoft Copilot Studio system for Sales — a Cloud Sales Assistant plus a Sales Coach sub-agent — and tested it against a 2,600+ page Cloud knowledge base on source citations, hallucination, FAQ approval flow and sales usability. Basis of my B.Eng. thesis (2026): a comparative analysis of AI assistance systems in the enterprise, productivity and cost-benefit potential. Finding: no single approach leads on every dimension — enablement decides.
