Which process model notation is usually associated with lean manufacturing related process modeling?

Value Stream Mapping (VSM) is the process model notation specifically focused on lean manufacturing. It is designed to visualize the flow of materials and information as it relates to a product or service, thereby identifying waste and opportunities for improvement in the process. VSM emphasizes the value-adding steps in the process and highlights non-value-adding activities, which is crucial in lean methodologies aimed at maximizing efficiency and minimizing waste.

The strength of VSM lies in its ability to provide a comprehensive view of the entire process from start to finish, helping organizations identify bottlenecks, delays, and areas where improvements can be made. This aligns perfectly with the core principles of lean manufacturing, which seeks to streamline operations and optimize resources.

Other process model notations, like Gantt Charts and Flow Charts, although valuable in their own contexts, do not specifically focus on eliminating waste or improving efficiency in accordance with lean principles. Gantt Charts are primarily used for scheduling and managing timelines, whereas Flow Charts provide a general overview of processes but lack the specific emphasis on value stream analysis. Integrated DEFinition Methods (IDEF) are broader process modeling methodologies that encompass various aspects of systems but do not specifically target the principles of lean manufacturing.
