Which process model notation is used usually in lean manufacturing related process modeling?

Value Stream Mapping is widely recognized as a crucial process model notation in lean manufacturing. It provides a detailed visual representation of the flow of materials and information throughout the production process, allowing teams to identify waste, inefficiencies, and areas for improvement. This approach aligns with the principles of lean manufacturing, which emphasizes the elimination of non-value-adding activities and the enhancement of value delivery to the customer.

In Value Stream Mapping, specific symbols represent different elements such as processes, inventory, and information flow, thus providing clarity and insight into the entire operation. This method goes beyond simple mapping by facilitating an analysis of the current state and designing a future state that is more efficient.

While UML, BPMN, and flowcharting are valuable modeling techniques, they are typically utilized in various contexts outside of lean manufacturing. UML, for example, is largely used in software engineering for system modeling. BPMN is designed for business process modeling with a focus on business processes rather than manufacturing workflow. Flowcharting is a general-purpose tool that can depict various processes but lacks the specific focus on value and waste that is central to lean practices. Therefore, Value Stream Mapping emerges as the most suited option for lean manufacturing process modeling.
