értékáramtérkép

An értékáramtérkép, often translated as a value stream map (VSM), is a lean manufacturing tool used to visualize the flow of materials and information required to bring a product or service to a customer. It is a key element of lean thinking, aiming to identify and eliminate waste within a process.

A value stream map typically depicts all the steps in a process, both value-adding and non-value-adding. It includes information about lead times, processing times, inventory levels, and the flow of information between different stages. The map provides a holistic view of the entire value stream, from raw materials to the final customer.

The primary goal of creating an értékáramtérkép is to understand the current state of a process and then design a future state that is more efficient and less wasteful. By visually representing the flow, teams can pinpoint bottlenecks, areas of excessive inventory, long waiting times, and other forms of muda (waste).

The process of creating a VSM involves walking the actual process path, observing operations, collecting data, and then documenting it. This hands-on approach ensures accuracy and a deep understanding of the real-world challenges. Once the current state is mapped, the team brainstorms improvements and creates a future state map, outlining the desired optimized process.

VSMs are powerful tools for communication and collaboration, helping teams align on improvement initiatives and track progress towards lean objectives. They are applicable across various industries, not just manufacturing, and can be used for both products and services.
