An introduction to Preventive Maintenance Group Schedules and Preventive Maintenance Routes using AssetOptics. In the PM Group Schedules lesson you will learn how to build a hierarchical preventive maintenance schedule whereby larger calendar interval PMs override shorter interval PMs. In the PM Routes lesson you will learn how to apply a single Work Task to multiple assets such that one parent (Route) work order can be used to plan maintenance on a series of like assets while still tracking maintenance history on each via a child (Route Stop) work order. This course supplements the more in-depth Quick Start Training Presentation (download). You should also complete the Quick Start Training Exercises for PM Group Schedules (download) and PM Routes (download) in your own training org.
