Works\nThis workflow automates engineering governance by deploying a multi-agent AI system that validates designs, checks compliance, optimises safety, and predicts maintenance needs. Designed for engineering teams, quality assurance officers, and operations managers in regulated industries, it eliminates manual review bottlenecks and ensures systemic risk issues are escalated promptly. A schedule trigger fetches design specifications and operational data, merges them, then routes to three parallel agent tracks: Design Validation (with Compliance Verification, Resource Coordination, and Testing Validation sub-agents), Safety Optimisation, and Predictive Maintenance. All outputs consolidate into a risk score calculator, which routes by risk level\u2014critical and high issues trigger Slack alerts immediately, while medium and low issues are logged for review.\n" }, "typeVersion": 1 }, { "id": "e28aa4e1-34ea-40d6-8b72-2418741d4fc2", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 768, -304 ], "parameters": { "width": 480, "height": 240, "content": "## Setup Steps\n1.
