IoT ensures transparency in manufacturing too. Sensors attached to plant and machinery record measurements such as revolutions counter, temperature and/or pressure measurement and sound an alarm in cases of discrepancy. That provides machinery manufacturers with an entirely new business model opportunity. Instead of just selling the machine, they can offer their customers added value in the form of predictive maintenance. An as-a-service model of this kind generates continuous revenue and strengthens customer loyalty. The user benefits from lower costs if machines are only serviced when necessary. Predictive maintenance can shorten or entirely prevent outages of plant or machinery. And a machine leased or provided on an as-a-service basis means the customer no longer needs to invest heavily and makes costs easier to plan.
