Predictive, or condition-based, maintenance is a shining goal for industrial customers and the Industrie 4.0 initiative. Supplementing, or even replacing, inefficient schedule-based maintenance with software promises to reduce equipment failures and unplanned downtime, improve safety and ultimately help the bottom line in an era of unstable prices and uncertain budgets. Predictive maintenance might be taking longer than expected, but in the next five years you might see it move faster than expected.
