The value stream method has become a standard approach for the analysis and design of production areas in many companies. However, the conventional method is designed for high-volume production. We propose a new value stream analysis and design, tailored to the specific needs of make-to-order companies. While maintaining the paper-and-pencil approach for data collection, we set a focus on schedule reliability and the required manufacturing control methods. The new method is presented by the example of an industrial manufacturer of precision parts.

This thesis develops a value stream method for the analysis and improvement of logistic objectives in a make-to-order production. The central element is the on-site recording of schedule reliability, throughput time and work-in-process. Additionally, the current configuration of the manufacturing control system is inquired and the complete flow of material and information is then charted. The following value stream design contains production planning and production control tasks. Concrete methods for the tasks order release, sequencing and capacity control support this process.

Value stream mapping (VSM) is a widely proven method to optimize a production. The practical approach, the manageable effort and the target-oriented procedure are the factors of success of this method. However, the method is of limited use when applied to make-to-order (MTO) environments. This paper aims to describe the shortcomings of VSM with respect to an application in a MTO production. The paper concentrates on the different logistic targets VSM impacts, as well as the manufacturing control tasks VSM applies. To set the basis for an application of VSM in MTO companies, requirements are described both for the logistic targets of VSM and the related manufacturing control tasks.
