At what frequency do you calculate the schedule compliance metric? Is it weekly, daily, or hourly? Depending on who you ask, you might come up with a different answer. For me, it depends on several factors. The first one is the level of Maintenance organization reactivity. That is followed by how long the organization has been producing next week’s schedule. It might surprise you but a number of organizations still don’t produce a formal schedule for next week. Another factor is the partnership between Maintenance and Operations.
