What are the challenges in predictive maintenance?

Predictive Maintenance Challenges

By collecting and monitoring data about intricate aspects of equipment processes — small changes in vibration, temperature and equipment sounds — a system is able to determine that maintenance is required, well before the equipment fails.

Why does predictive maintenance fail?

There are many causes for this, ranging from a failure to commit adequate personnel, lack of proper training, loss of skilled personnel, change in program direction/technology, failure to adequately define the program at the start and, finally, the lack of a consistent model to monitor the efficacy of the program over …
