Your operation has been reducing Mean Time Between Failures (MTBF) and the Mean Time to Repair (MTTR) steadily for the past few years. Your operation is perhaps well down the road toward implementing preventive maintenance solutions and may even be starting to implement predictive maintenance methodologies. Given the effort it has taken, you are very proud of your planned maintenance schedules, your team's adherence to them, and you are experiencing less and less unplanned equipment downtime. Good.
It's now time to begin reducing or eliminating planned maintenance.
This is the attitude your maintenance department needs to have to sustain the uptime gains and continually improve your process reliability, as strange as it may sound at first.
All maintenance is essentially rework or is technically considered 'non-value added required' waste. Getting your equipment stabilized and performing better took a lot of effort, but now there is still problem solving that can be done to reduce or eliminate maintenance through better equipment design and further simplification. And now that your maintenance experts have more planned time, they could apply that expertise and natural proclivity for problem solving and troubleshooting to an innovation process and help develop the next generation of equipment. Could that give you a competitive technical advantage or even lead to a new line of business?
