Phase 1: Assess Data Readiness andd Infrastructure

Before jumping to analytics, audit yourr curt CAM environment. Do your machines have thee necessary sensors andd connectivity? Is there a data historian or edge gateway in place? If not, invess in retrofitting older machines with ioT adaptors (e.g., using OPC DA to OPC UA gateways). Also assess network bandwidth and latency recondifficients.
