We sit down for our weekly maintenance scheduling meeting and present our operations counterparts with a schedule that requires 4 hours of downtime in the middle of the week. They immediately start horse-trading and ask questions like “can you do it in 3 hours?” or “can’t we just skip it this week?” Why do they ask such questions? It is because they do not really believe that these proactive maintenance tasks are necessary; they don’t believe that they add any value.
