New information and communication technologies such as the atomization of demands have a continually stronger influence on business models and processes and force companies to integrate the value chain and open them for suppliers and customers. Modern information systems are a prerequisite for the interconnected digital world, the so called «Industry 4.0». For many years, the PlenarIT AG successfully utilizes the holistic consulting approach of a symbiosis of management consulting and information and communication technology (ICT) consulting. With this we ensure the business to IT alignment from day one. The fourth industrial revolution requires individually customized offers which will also be shaped by customers. Furthermore, the products have to contain intelligence and be connected with services. The new information and communication technologies are a crucial lever to this. The information system 4.0 has to connect all information of facilities, machines and components in real time to optimize the planning and control of the entire value chain, from the supplier and the production to the customer.
