Before the advent of Industry 4.0, the service technicians used to drive to customers to maintain or repair machinery and equipment while often following a route that is dependent on a defined preventive maintenance schedule. 

The prevalence of Industry 4.0 in manufacturing and production could possibly change that as it allows setting up secure remote access to distributed assets. This can help machine and equipment manufacturers to effectively optimize maintenance while offering the best possible maintenance support. Instead of having to drive to the customer’s premises when after-sales services are required, the service technician can access the customer’s machinery remotely in order to diagnose the source of the problem or to support the customer during installation and maintenance. In both cases, the customer benefits from quicker response and completion times for services and problem solving.
