The researchers of the Lean Aircraft Initiative developed a hypothesized leanimplementation model seeking to provide its members guidance on implementing leantransitions in factory operations of low volume/high complexity production systems. The modelfeatures four phases: (1) building a lean infrastructure to support lean behavior, (2)redesigning the flow of products in the factory, (3) revamping the operations management and(4) fostering process improvement. An order of implementation is discussed and each phasehas implementation steps as well. Following the development of the hypothesized leanimplementation model, twelve case studies were used to test the model. This report details themodel and analyzes the case studies using the model as a framework.
