Many manufacturers lack comprehensive and seamless management for the change processes occurring between planning and the shop floor – particularly when it comes to cross-location, cross-disciplinary, and cross-departmental planning. This paper describes the emergence of the PSI/VDA recommendation which addresses this challenge. It's Manufacturing Change Management (MCM) defines a reference sequence of steps for managing the changes between planning and the shop floor. To define this reference process, the recommendation first discusses how MCM fits into the business environment and identifies the main participants of the change processes. Next, the best possible structural steps involved in the processing of a change enquiry are detailed and the typical tasks and their extents are described. Leading on from the conceptual basis of the MCM process, its suitability for specific applications within companies is then discussed in reference to relevant use cases. Next, the recommendation shows how to work out a software-based support structure for the concept and implement as a prototype. The key element of the software-based implementation is to map the changes within a superordinate change list. Lastly, the solution provides an easy-to-use practical tool for initiating change enquiries. This can be deployed flexibly on mobile devices such as tablet PCs on the shop floor.
