The cost of transmitting data from machines to data repositories has also fallen. In the past, operational data generated by a machine was collected manually by a technician on the shop floor. Today, that data can be send wirelessly to the Internet via Bluetooth or Wi-Fi.

Not All Work Is Created Equal

Another problem facing traditional preventive maintenance scenarios is the assumption that every machine of a certain type will be operated under similar conditions or within similar parameters. Clifton Triplett is Managing Partner of SteelePointe Partners, a management consulting firm. He is also a former CIO at Baker Hughes, a $20 billion global oil field services business, and manufacturing process executive at General Motors. A West Point graduate, Triplett knows firsthand that equipment is often operated in situations and circumstances that can be unforeseen by the design engineer or manufacturer.

“It’s important to remember that not all work is created equal,” Triplett says. “If you run a tool within its designed operating constraints, it will require a certain level of maintenance. But if you run it outside, well under or over normal operating specifications, a different level of service is generally going to be optimal.”

For example, a truck designed primarily to deliver mineral ore in Canada will require a different level of service if it’s used to haul ore up and down mountains, on flat paved roads, or across dirt roads in a hot, dusty desert. In the oil and gas business, a drill bit primarily used in conventional “straight down” drilling operations will require different reliability parameters and service requirement when compared to a bit being utilized in more challenging unconventional horizontal drilling. Reliability is in part defined by design, but reusable equipment is highly dependent upon the maintenance services performed on it.

“In the military, we would run tools and equipment in as many different scenarios as possible to understand how they would perform and react to the different environments,” Triplett says:

We would test equipment at various altitudes, temperatures, and levels of humidity. We would test equipment to see whether freshwater or saltwater would affect its performance. You name it, we tried it and we assessed how we should adapt our maintenance schedule to adapt to the conditions we place our equipment.
