IoT & Predictive Maintenance Readiness Checklist

Is machine downtime/failure data recorded historically (at least 3 months)? Is there a PLC/SCADA with accessible data (Modbus/OPC-UA/etc)? Is network connectivity available at the machine/line location? Is there an internal OT/IT team supporting this project? Is there budget that can be allocated for a pilot project? Is there management support for this digitalization initiative? Is there a specific use case/problem already identified? Is there a data security policy for operational/OT data?
