There is a number of barriers for smaller companies when starting the journey toward Industry 4.0. When implementing new technology and processes, there are often strong mental barriers from people that have been doing the work in a certain manner over the years. In addition to technological challenges, organizational adaptations are required, and a change in mindsets. Using the case of one machining services company, the implementation scenario is described, with the steps necessary to ensure an effective implementation of new technology. The management of visibility is critical for the adoption and success of new systems. Neglecting the human factor will inevitably result in failure. Derived from the case, the chapter draws some conclusions for Industry 4.0 implementation in SMEs in a human-centered manner.
