For an AI-based predictive maintenance system, PMI-CPMAI–aligned practices emphasize that the fitness of the data for the AI task must be validated in terms of accuracy, resolution, and timeliness before committing to model development. In the context of sensor data, this means confirming that measurements are precise enough to detect early degradation, sampled at a sufficient frequency to capture relevant patterns (resolution), and delivered with low delay so predictions are actionable (latency). A data quality assessment focused on precision and latency directly addresses these concerns by examining how close sensor readings are to true values, how stable they are over time, and how quickly the data flows from the equipment into the AI pipeline.

PMI-CPMAI guidance on data readiness for AI systems stresses profiling and testing data for measurement error, noise levels, sampling intervals, and end-to-end delivery lag before deciding if data is suitable for predictive models. Activities like schema review or feature engineering are important but come after confirming that raw data quality (especially precision and latency) meets the minimum requirements. Implementing governance frameworks or adding more sources does not, on its own, validate whether the existing sensor data is accurate and timely enough. Therefore, the method that best addresses the stated requirements is performing a data quality assessment focusing on precision and latency.
