"content": "## Workflow Overview: Supplier Churn Prediction & Retention Intelligence System\n\nThis workflow automates end-to-end supplier risk monitoring for procurement teams by analyzing supplier behavior data stored in Notion, generating AI-driven churn predictions, and producing actionable retention strategies. It continuously evaluates supplier performance using behavioral signals such as purchase order trends, delivery reliability, payment behavior, and engagement metrics. Based on these patterns, the system classifies suppliers into risk tiers (Low, Medium, High), generates key risk drivers and confidence scores, and recommends targeted retention actions such as renegotiation, payment term adjustments, and performance-based engagement strategies. High-risk suppliers trigger real-time Slack alerts, while all suppliers are updated in Notion to maintain a live supplier intelligence system.\n\n## How it works\n\nThe workflow runs on a weekly schedule and pulls supplier data from Notion. It converts raw procurement metrics into behavioral signals like PO trends, delivery issues, payment delays, and engagement scores. These signals are sent to an AI model that predicts each supplier\u2019s churn risk and explains the key reasons behind it.\nFor high-risk suppliers, a second AI step generates targeted retention strategies such as renegotiation suggestions, improved payment terms, and relationship actions. Finally, all suppliers are updated back into Notion with their risk scores and insights, while only high-risk cases trigger Slack alerts for immediate procurement attention.\n\n## Setup steps\n\n**Schedule Trigger** \u2014 Runs workflow on a weekly schedule. \n**Fetch Supplier Data (Notion)** \u2014 Retrieves all supplier records from database. \n**Feature Engineering (Code Node)** \u2014 Calculates behavioral metrics and risk signals. \n**AI Churn Prediction** \u2014 Predicts supplier risk level with reasoning and confidence. \n**Parse AI Output** \u2014 Structures AI response into standardized format. \n**Check High Risk Supplier** \u2014 Routes only high-risk suppliers for escalation. \n**AI Retention Strategy Generation** \u2014 Creates actionable retention plans for high-risk suppliers. \n**Parse Retention Output** \u2014 Structures retention recommendations. \n**Update Notion Database** \u2014 Stores churn scores, drivers, and retention insights for all suppliers. \n**Send Slack Alert** \u2014 Notifies procurement team for high-risk suppliers only."
