Value Stream Mapping

What is Value Stream Mapping?

Value Stream Mapping (VSM) is a method used to visualize and optimize production and business processes, focusing on identifying value creation and waste throughout the entire production flow. Originating from Lean Management and the Toyota Production System, Value Stream Mapping looks at the production process as a whole, from raw material procurement to the finished product, in order to identify improvement opportunities.

Goals and Benefits of Value Stream Mapping

1. Identifying Waste: One of the primary goals of VSM is to identify non-value-adding activities (e.g., waiting times, overproduction, unnecessary movements) and eliminate or reduce them.

2. Process Optimization: By visualizing the current state of a production process, bottlenecks and inefficiencies can be identified, providing a foundation for informed process optimization.

3. Increasing Efficiency: Analyzing and improving processes increases productivity and reduces costs. Resources are used more efficiently, and lead times are shortened.

4. Improving Value Creation: A clearer overview of the entire production process allows companies to take targeted actions to increase value creation while improving quality and customer satisfaction.

Phases of Value Stream Mapping

1. Mapping the Current State: In this phase, the current value stream is recorded. All steps required to produce a product are documented, including material flow, information flow, and time spent.

2. Designing the Future State: After visualizing the current state, a future state map is developed to show how the process should ideally operate, minimizing waste and maximizing efficiency.

3. Planning Improvements: Specific actions are defined to address bottlenecks and optimize the production process in order to achieve the future state.

4. Implementation and Monitoring: The planned actions are implemented and regularly monitored to ensure that they achieve the desired effect and drive continuous improvement.

Connection to OEE

Value Stream Mapping is a valuable tool for improving Overall Equipment Effectiveness (OEE) by helping increase the efficiency of machines and production processes. By reducing losses such as downtime, waiting times, and defects, companies can significantly improve their equipment effectiveness. Combining Value Stream Mapping with OEE optimization allows for sustainable improvements in production performance and strengthens competitiveness.
