This document discusses horizontal and vertical integration in Industry 4.0. Horizontal integration refers to the exchange of data across all objects, departments, and companies within a network. Vertical integration ties together all logical layers within an organization from production to other business units. The benefits of integration include improved visibility, flexibility, productivity, and automation. Integration can occur both within a company and across the supply chain. Cloud-based integration using service-oriented platforms allows data to flow freely between all levels and business units.
