Production Yield Analysis (PYA) is a structured system approach to optimize the production yield of production processes. The paper outlines the developed method and the 10 basic steps of the PYA. The PYA-method makes it possible to calculate the Yield Index of a process. This dimensionless figure can be used in balanced scorecards; it visualises the true raw material efficiency of the production process and enables fact-based management, which is the key for yield improvement, cost cutting, waste reduction and saving raw materials.
