A Process Development Execution System (PDES) is a system, which is used by companies to perform development activities for high-tech manufacturing processes. A PDES is similar to a Manufacturing Execution System (MES) in several aspects. The central distinguishing factor is that PDESs are tailored for steering the development of a manufacturing process while MES are tailored for executing the volume production using the developed process. Therefore the focus and the toolset of a PDES is more on lower volume but higher flexibility and experimentation freedom. The tools of a MES are more focused on less variance, higher volumes, tighter control, and logistics. Both types of application software have in common that they increase traceability, productivity, and quality (for PDES the quality o
