Almost 20 years ago, the introduction of computer-driven automation brought fundamental change to the manufacturing industry. Today, with the advent of the Internet of Things (IoT), manufacturing is changing again. The traditional factory floor already accustomed to interconnected production means along a predefined hierarchy, with every asset working together to achieve efficient production at optimal costs. With SIM-enabled IoT, new “smart factories” are envisioning a hyper-connectivity that maintains constant data flows along every link of the value and supply chain to close information and inventory gaps, increase operational efficiency, and lower overall manufacturing costs. This new level of connectivity, backed by IoT and SIM technology, has led some to declare SIM IoT manufacturing as the fourth industrial revolution, or Industry 4.0.
