Every organization is different. Just as there might be one person in a planner/scheduler role, there might also be only one Maintenance/Reliability Engineer. But, if we were to talk about the ideal org chart, it might be as described as follows (from Paul Barringer).
- The task of a Reliability Engineer is to prevent failures. This is a strategic task.
- The task of a Maintenance Engineer is to quickly restore the failure to an operable condition. This is a tactical task (often driven by adrenaline for timely restoration).
